  1. Hi Yashwant Naik sir.

    I have 4 inch flowerhorn and my tank size is 19 inches by 9 inch, i have only power filter and heater in tank.

    My problem is we are totally depended on borewell water, can u suggest a solution to keep my fish happy and healthy in the water available in our area.

    Awaiting your valuable reply.

    1. Hello Mohammed Hussain,

      Well some flowerhorn adjust with Borewell. I would recommend to you that :
      1) Before changing water of tank always store water in bucket or drum for 48 hours. You can add 1 table spoon Rock Salt (raw salt) in same bucket.
      2) Avoid frequent change in water
      3) Check for pH level of water before adding to tank
      4) Never change 100% water
      5) Weekly change or clean the filter sponge.

      For any further query you can reply to this.

      Thank you,

      Yashwant Naik

    1. Hello Akshay,

      Deworming Process is not so mandatory. Deworming process includes cleaning of stomach and bad bacteria.

      Their are many process are use for deworming fish.

      Actually it is not important to do so.

So before he gets white poop disease or bloated stomach what precaution should i take and even after precaution if he gets then at earlier stage what should i do…. What medicine should i use and how can u use…… Can u explain it briefly

        1. Hello Akshay Gharat,

          Bloated Stomach and White Poops are very dangerous diseases.
          The main reason for this is –
          1) Over Feeding
          2) Feeding Flesh, Meat or Live Fish
          3) Bad water condition in tank
          4) Wrong filtration
          5) No maintenance of tank

          Paraclear is only solution to get rid of that disease, but no preventing medicine available in market.

          TO keep fish healthy you need to follow some steps , so let me know if you want to know them

          Thank you,

          Yashwant Naik

    Thank you

    1. Hello Akshay.

      If you’re using Ocean Free Product than I recommend you should not use any other medicine, as it may contradict to each other.

      To keep fish healthy you need to follow certain process. The Ocean Free Medicine you wont help to keep protected from Diseases.

      Please follow below process –

      1) Do 20% water change once in week but avoid frequent water change in Monsoon. Increase gap of water change. During this gap you need to clean filter sponge and surface of tank.

      2) Use Ocean Free DeChlorinate Special as Anti Chlorine Solutions (can buy from here – ) instead of local anti chlorine

      3) Each time Use Ocean Free Gill Fungus Parasite Special

      4) Dont use Power filter as source of air, use separate pump with medium speed.

      5) Use Heater during night

      6) Use Filter few hours in day, if possible use Slow filter

      7) Dont use decoration

      8) Feed him on specific time – dont feed all time

      9) If possible avoid direct light on fish

      In case any issue or difficulties you can communicate via just commenting here.

      Thank you,

      Yashwant Naik

      1. thank you sir for your guidance…… I didnt use any decoration only 1 hiding decoration i have added and 1 sponge filter and air stone with bio filter with ceramic rings

          1. Hello Shouib,

            Normal Tap water is best for flowerhorn. If you don’t have access for municipal water then you need to use water conditioner for water.

          1. Hi Bharath,

            You can use Aquaria Clear to remove algae.
            Water change is important task to do. So, if you do weekly water change than you no need to use such product.
            Also flowerhorn do lots of waste so aquaria clear wont work.

            So, you decide.

            Thank you,

    While changing the water why do we have to add two drop of OceanFree Gill Fungus and Parasite Special

    Because this will make the fish immune to fungus and parasite .

    But later when we will actually need this OceanFree Gill Fungus and Parasite Special and at that time there will be no effect and this will not work

    So instead of OceanFree Gill Fungus and Parasite Special why shouldnt we use Bacto-active ??

    Please we need some suggestion on this ??


    1. Hi Vinod,

      Thanks for commenting n asking query.

      We use Ocean free gill fungus parasites special while Changing water so it remains protected from bacterial infection.

      We use AntiChlorine which reduce the hardness of water and with chemical reaction clean water too. But every AntiChlorine do same..

      Even using AntiChlorine won’t reduce or fight to some bad Bacteria.

      Fish are very sensitive to water change and due to some bacteria leads to stress, White spot or other diseases.

      Using Ocean free gill fungus parasites special few drops can be helpful. So, we are protecting fish and not making use to it.

      So, you won’t face such fish dullness, sick or stress.

      I hope this will fullfil your doubt.

      Happy to help you.

      Thank you,

      Yashwant Naik

      1. Dear Yash,
        I really appreciate all your help and support
        I have one query-
        I took a bucket and poured the amount of water which had to be replaced and i kept a heater to match my tank water tempeature for entire night and then the next day 20 th august 2016 before replacing the water i poured Anti chloring and kept it for 20 minutes and after replacing 30 %water from 104 litre tank ie 25 gallon tank and the next day i saw the fish’s tale was slightly torn or eaten away

        So today ie 22nd august the very next day i desscided to add 2 spoon of aquarium salt and one cap ocean free fungus parasite spec with temprature 28 and air pump and external bio filter.

        Just to remind that after replacing the water i had not used the aquarium salt and ocean free fungus special
        I have not fed my fish since yesterday

        Need your advice here!!!


        1. Hi Vinod,

          Few mistakes you did while changing water.

          You no need to keep on heater whole night.

          This indicate you need faster heater.

          The rotten fin can be because of water change. A new water may contain heavy metal which cause to this.

          Please specify which AntiChlorine are you using?

          Yes, Vinod I always recommend to use :-
          1) AntiChlorine
          2) ocean free gill fungus parasites special
          3) Rock salt or Epsom salt

          on every water change.

          This will protect fish from side effects of water change.

          Thanks for commenting,

          1. Hi Yash,

            I had to use a normal anti chlorine white bottle 10 rs , because i had ordered RID All Anti chlorine which arrived today
            The salt which i usd is Lagoon Aqua Ocean free Treated aquarium salt.

            Now what shld i do ??

            I havent fed my fish !!

            Should i wait and change the water this coming sunday or change it now

            Will it effect the tail or should i quarantine the fish for treatment and treat the tank if yes then how should i do that ?

          2. Hi Vinod,

            Dont wait till Sunday for water change.

            Kindly Do 30% water change with Salt and Anti Chlorine.

            Please make note that you should not use Rid All and Oceanfree brand together.

            I personally trust Oceanfree for all type of treatment.

            Thank you,

    1. Hi Goutham,

      I suggest you get bigger tank atleast more than 3 feet.

      1. hello sir,
        I lived in utter Pradesh,Allahabad,India
        I have a 4 ft tank with gravels…withonly flower horn
        I changed 20% water every week
        now my flower horn sitting in the bottom for last 4 days with swollen stomach
        I used tummy wash but its not working
        pls give some suggestions to cure him
        thank you

  20. I have one flower horn aged near about one year & have no experience of flower horn though
    I am keeping different type of aquarium fish for last ten years. Now I have observed that my fish
    is not eating properly for few days after changing 30% water of my tank. My tank size is near about five feet. As per advice of my friend I have used one antibacterial tablet& did not give any food for one day still then I found not eating properly so I used another antibacterial tablet since capacity of tank water huge. No batter result I observed.Yesterday I observed white mucus type sticky jel in the stool. Then I tried to know in the internet in your side and came to know this is known as white popping and today morning I purchased your recommended medicine Oceanfree (Paraclear) & mixed half of the pack to tank water and stopped feeding for three day as you have recommend and then I shall repeat the process after three days.
    Now I want to know after three days shall I give the fish little amount of food. I use dry food (humpy head, Quicker, Platinum & Wild flower horn food).
    I shall be waiting for a line in reply.

    1. Hi Pradeep,

      It’s pleasure to know that you referring my blog information for Flowerhorn Treatment.

      For Paraclear treatment, it’s not recomemend to feed Flowerhorn during course of treatment.

      The Paraclear treatment need to follow till you don’t see WHITEPOOP discharging from Flowerhorn.

      Check Flowerhorn at third day, if he is recover from white poop than you no need to continue.

      But feed him one days gap. And dot deed live food for one month keep him at pallet.

      Thank you,

      Yashwant Naik

      1. Your reply is very helpful to me and also I am grateful to you. Now I find my flower horn is very hungry always indicating to feed him. I find no WHITEPOOP in the aquarium after I have cleaned on 15/7/16..As per your instruction whole day I shall watch then tomorrow morning I shall feed him.Now you tell me before feeding shall I reduce 30% water & clean the tank.Shall I start the power filter on or not. You also advise me what are the medicine required for emergence. Is there any expiry date of medicine for use.
        Reg. vegetable live food i.e. peas I want to know where shall I get. Is it available in a pouch. Just guide me.

        Thanking you,

        1. Hi Pradeep,

          It is nice your Flowerhorn recovering fast.

          Well change 30% water and fell fresh water o tNk

          The expire date for medicine are viable depending on medicine.

          You can feed him after two days.

          You can give him green pea.

          Also please take care while water change. Use water conditioner too.

          Thank you

  21. hi there, I am getting electric shock when I put hands in my FH tank…I get shock where I have got cut on my finger. Then I called an electrician, he took one copper wire. He inserted one end of wire in Fish tank water and other end to the ground outlet in standard 3-Pin plug. so I want to know is fish is getting shocked???

    and whatever that electrician did is correct??

    1. Good Evening Ganesh,

      This is totally worng method.

      You suppose to do house earthing instead of doing this.

      Also it won’t work as your home don’t have earthing outlet.

      Thank you,

    1. Hello Prabhu,

      Why it happening ? I guess your Tank is located near to window. You need to keep tank some where direct Sun light enter to Home or dark place where temperature remain same.

      Sudden change in Temperature can cause stress and irritation.

    1. Hi Vivek,

      Which fish you have with Flowerhorn.

      Ideally this won’t happen as aggressive Flowerhorn either eat them or kill them.

      Since it happened you need immediate action , they are –

      Note – take Flowerhorn from tank to Bucket with same Aquarium water.

      1) remove other fish from tank

      2) clean entire tank with warm water

      3) clean filter n oxygen stone

      4) now fill water to tank

      5) add heater and make it 28° , use only at night.

      6) put ten drops of Ocean free gill fungus parasites special.

      7) five drops of dechlorinate

      6) now add Flowerhorn to tank

      Every day you need to change 10% of water n add two drops of Medicine OCEAN FREE GILL FUNGUS AND PARASITE n dechlorinate.

      Keep me posted.

      Thank you

      Yashwant Naik

          2. Hi Vivek,

            We need Oceanfree Paraclear for treatment. I m not sure with paracure.

            Please get it ASAP.

            Thank you,

            Yashwant Naik

  26. Hi sir…my fh can’t eat well it eat 2-3 pellet remining are bite & spit & it like to eat dried foods only..previous sunday i partially change the water in aftrnoon…while changing i add stress heal (water conditioner and external parasites for prevention) the fh looks black colour & stay near to filter..whether i don’t the problem arise for water change in aftrnoon or due to new medicine added ( stress heal water conditioner).aftr changing water temp goes to 36¤…hlp me sir….tq

    1. Hello Vivek,

      The water change goes worng.

      The medicine was not work, I would like to know brand and name of Medicine.

      Now quickly do this,

      Do partial water change of 20%

      Clean water filter with warm water

      Add one spoon of sea salt.

      Once I understand the medicine I can suggest u more.

      Also reduce the heater temp to 28 and use only nights


      1. 1. Brand – stress heal.. thats for removing toxic gases and it contain aloevera.. first time using this medicine in previous water change..
        2. Brand – Ocean free T2…thats for external parasite..i use medicine more than two month for prevention & i can’t see any defects in this 2mnth..

        Water temp is in 36¤ how i decrease this..u told that to set heater at 28¤ if i set that the heater doesn’t on bcoz water temp is 36¤ na

        1. Vivek,

          Okay, I have no experience with those medicine.

          Instead of ocean free T2, I recommend to use OCEAN FREE GILL FUNGUS AND PARASITE SPECIAL. it have great result out come.

          also, you can’t use two medicine other than water conditioner. As water conditioner I recommend OCEAN FREE ANTICHLORINE.

          As for now you follow what I recommend in earlier comments.

          For heater stop using now.

          You can use heater at night

          Or don’t use it if room temperature is more.

          Where do you live ?



          1. Okay tq sir.. I’m from my question is how to reduce water temp..adding ice cubes is good to reduce temp

          2. Hello Vivek,

            No don’t add ice cube.

            You stop using heater.

            Fast air pump and keep ON power filter.

            Your Flowerhorn is not eating foods for that you have to do this trick –

            Keep in dry shrimp in your Flowerhorn food box. Slowly the smell of dry shrimp mjx with food and this will help to eating food.

            Thank you


    1. Rajan,

      Deworming is lenghty process, need expert supervision.

      Let me understand why you think so?

      What exactly happening to your Flowerhorn?

      After that I can suggest something best for you.

      Thank you,

      Yashwant Naik

      1. Few days he don’t eat well..when i feed he eat 2-3 pellet remaining pellet are bite & spit..suppose if i feed dried food like shirmp he eat superb… nthng defects in activity & appearance..

        1. Hi Rajan,


          Keep dry shrimp with pallet. It will eat.

          You don’t need deworming for Flowerhorn.
          Your Flowerhorn is fine enough.

          Thank you,


    1. Hello Rajan

      Don’t mix direct water conditioner with Medicine.

      Better first add water conditioner and after five mins add Medicine.

      Thank you,


  27. Hi frnd have fh…that can’t eat more a week & become too slim & standing back to filter..colour also gets black

    1. Hi Vivek,

    1. Hello Vivek,

      Your fish problem arise because of two reason –

      1) bad water
      2) live feeding parasites

      Every live feeding consist some bad bacteria which harm Flowerhorn.

      Also borewell water need to be conditioner before you use to Aquarium.

      Flowerhorn fish is very delicate and has low immunity.

      You need two medicine –

      1) grand fish clear water safe
      2) ocean free gill fungua parasites special

      You need to do 10% water change in five days and use 5 drops of this medicine.

      Install heater and turn to 30°

      Stop using power filter untill treatment.

      You can buy product from –

  34. hi sir I bought my flower horn 1 month ago he had a good head then.but stressed from the day I brought him and his head completely gone like bone head flower horn and dark lies at bottom rarely moves and hides when I go near him pls help sir I uses 7 in 1 fish Dr but dono wat to do I use UV water

    1. Hello Rahul,

      Sorry for late reply.

      Before I start with any treatment let me explain why this is happening.

      UV water or RO water can damage the Flowerhorn health. Flowerhorn needs fresh water so at cities tap water with chlorine is usable and ideal.

      But at same time chlorine is not good for Flowerhorn.

      So you need to use water conditioner such as –

      1) grand fish water safe for fresh water.

      2) while changing water – first make solution of this medicine. Take a water bucket and put Grand fish water safe and mix well and than put the water to tank.

      The head can be recover if you follow diet plan and hygiene water conditions.

      For now you get Grand Fish clear water safe for fresh water and start using.

      Do once a week 10% water change

      Add medicine


      Keep temperature balance.

      Thank you,

      Yashwant Naik

  38. Dear Sir,Read your article exactly the same back from my three day vacation came home today my Flowerhorn was dark,I added 3 spoon of Rock salt when I left,So I changed my water 30%..Now the colour lightened..But at present I am in Crisis..FH is settling at bottom,lethargic..Is it pH/temp problem?Kindly help me out..Can I add some salt

    1. Hello Sir,

      It’s seems your Flowerhorn because of change in water conditions due to course of time.

      A per your information your Flowerhorn turn dark which happened due to bad water.

      Water change reduce the stress but their is something in your tank n filter which causing problems.

      So you need water treatment liquid such as water care and general medicine like Ocean free Gill fungus parasites special.

      Cleaning process –

      Clean the filter n stones with warm water. Filter sponge n pipes need to be kept for Mins in warm water and the motor need to be clean with running water.

      Clear the tank glass with wiping sponge.

      Now add ten drops (3ft tank) of ocean free Gill fungus and parasites.

      After three days do 20% water and that time use water treatment liquid mention above.

      Do let me know if you need any further assistance.

      1. Hi Venkat,

        You need to do this –

        Use proper water
        Add tetracycline 150 mg for this.
        Turn heater 28.

        Also feed well you can see improvement in fish.

      1. thank u very much Sir,
        im feeding it with XO Humpy Head.
        how many times should I feed? for my 3″FH and how many pellets should I feed?
        he can eat 4 pellets at a same time.
        pls reply

          1. Hello Venkat,

            Yes, Thrice in day.

            Put that much pallet which he finished in less than mins.

            Also if you change the food than always mix the food so old food taste slowly change to new food.

            Thank you,

  45. Dear Yashwant ji, I bought a flower horn about two months ago. I was feeding her ” humpy head” 25 to 30 granules a day also was cleaning the entire aquarium in every 15 days, as the shop keeper suggested. The aquarium has some pebbles, one filter pump and one air pump. It was 4 inch and energetic when I bought.
    One month ago suddenly it stopped feeding and became lazy. I called the shop keeper, he suggested to put a aquarium heater on 28 degree also to give metrogyl tablet thrice a day. I did all. The heater is inside till then. Slowly I was seeing it is becoming more lazy and colour is fading. In the meantime almost 20 days ago I saw white spot on left eye. I ask the aquarium guy, he said nothing.almost 5 days back I saw that eye has become white and another eye also whitish. It was eating less and very slow. I became very sad full and bought a new one 3 days back and put in the same tank after putting a glass wall in the middle. The day I bought the second one I met a friend near by who has four big flower horn. I called him home and show the weak fish. He suggested to use a tetracycline 500 mg capsule. The aquarium water has become darker. That weak fish has not eaten anything today. I became worried.
    From the evening I was searching for flower horn fish disease and recovery and I come across your blog then FAQs. Could not stop myself, so I am writing this. Now tell me what happens to my first fish and will this tetracycline capsule effect the new one or what shall I do?


    1. Hi Mukti,

      Your Flowerhorn is suffering from several bacterial infection due to water. Also you put danger to another fish by occupying him with ill Flowerhorn.

      First of all you sperate them immediately in new tank. Other wise you loose both fish.

      To treatment Ill fish you need separate tank can be small or can use bucket. But this treatment goes for more than two week.

      Here are steps to do –

      Medicine –

      1) Ocean Free Gill Fungus and Parasite special
      2) water clear solutions

      Steps –

      1) clean your treatment tank with warm water
      2) clean air stone
      3) and filter sponge, we will not use filter while treatment
      4) now add water to tank
      5) five drop of water clear safe
      6) 10 drop of Ocean Free Gill Fungus and Parasite special
      7) turn on heater for 28′
      8) after 20 mins add fish to it.

      Don’t feed him while treatment.
      Never stair him
      Keep him in dark and keep observing

      You can get this product online –




      Thank you,


      1. Dear Yashwant ji , as I was worried very much also my family. I gave the weak fish to that neighbour who has another four flower horn, this morning.
        Now I have only the new one but in the same old tank in the same water. Please tell me what I have to do.

        1. HI Mukti,

          No problem than. You have to clean entire tank than as mention in Last comment.

          Also get those product to keep water clean and safe for FLower horn.

          Thank you,

          Yashwant Naik

  46. my flowerhorn has turned darker in colour…he is eating fine and head is also good…just the colour of body and fins have turned very dark…any solutions…it is from last one month…

    1. Hi Sumit,,

      It seems your Flowerhorn is affected because of bad water.

      I would suggest you to get the rock salt and put some on tank.

      Also clean you filter n air stone with warm water.

      Keep posting me about Flowerhorn.

      Also feed less. Never keep pallet lying in tank, if uneaten remove it.

      For precautions get good fungus liquid for safety.

      Thank you,

      Yashwant Naik

  47. hi,,,

    kindly advise….

    1. Hello Sachin,

      Don’t feed now as your fish is now suffering Parasite infection. You need to start treatment for white poop.

      But Ocean Free paraclear, from eBay or shop.

      Once you get do let me know.

      Thank you,


      1. but it is very rare .. when i do water change then only he is doing….
        currently occen free white spot is already there in tank….

        1. Hi Sachin,

          White poop is not visible when water is diluted..

          That’s why you see in fresh water.

          Please get Ocean Free white poop medicine and start it
          Thank you

  49. Sir

    My last flowerhorn which i bought 2 months ago died don’t know why her skin and an eye got white their were to many ants nxt morning on the tank fish was swimming one sided shopkeeper said that see might have eaten ants but she was not eating for more than 10 days i want to know the cause

    1. HI Srijan,

      Kindly accept my condolence for your pet.

      As you mention your Flower Horn skin and Eyes got white. This shows clearly problem with water. The bad cause several fungus and cloudy eyes (white eyes) problem for flower horn.

      Ant wont bite fish until it died. What your Aquarium Guy says is false.

      Also Flower horn can live without food for one month atleast.

      I can say your Flowerhorn died because of bad water condition of tank. Flowerhorn need clean and hygiene Aquarium.

      Keep reading my blog from more information about the Flower horn and its maintenance.

      Thank you,

      Yashwant Naik

  51. Hi Ashish,

    You need to change 10% water only every week.

    And you need to have heater and bio filter in tank.
    Bio filter need to clean when you do weekly water change.

    Use ocean free gill, fungus and parasite special while you do water change.

    Do let me know if you have any other issue.

    Thank you,

      And take bucket – add new 20% water in bucket and add dechlorinates drops.
      Add 1/3 of Paraclear.
      And keep for three days.

      And repeat in three days again if problem persists

      1. Gm sir,
        Tofay i have to change the watar how much water i should change.
        And how much time it will take to cure.


          1. Oh Sachin,

            Its dropsy. Very difficult to cure. But yes paraclear will cure it. But takes huge time.

            You need to take care few things –

            1) you cant change entire water, partial water change can do
            2) you can’t use multiple medicine, please consult before using
            3) you have to maintain temperature of tank, while partial water change you have to make sure you keep same temperature
            4) don’t stair Flowerhorn
            5) keep air pump on
            6) you can’t keep any decorative item in tank
            7) don’t panic just follow treatment

            In case any issue don’t forgot to inform me

            Thank you,

            Yashwant Naik

          2. should i feed him , cause i didnt feed him form last 3 days, and how much time it will take , from last 5 days its start happening, how much time will it take to cure.
            please suggest something.

          3. Sachin,

            As I told you earlier it wont it. And its stomach infection so not suggest to feed.
            Also it takes time to recover. This how the treatment goes.

            And flower horn can live without food for more than month.

            So please concentrate on treatment is important.

            Thank you,

            Yashwant Naik

  52. Hello sir! Its Ashwanie here. Sir I need help regarding the medications u suggest.they r not availbl at my city aquarium store.they normally sell RID ALLS medications. So plz can u suggest me some online sites so that I can buy them n use them in emergency cases. I only found ocean free gill fungus parasite special from amazon. M having 1 flowerhorn which I hav shared with u in our last chat. Thanks for ur useful n fast rplys.

    1. Hi Ashwanie,

      Rid All is common treatment for all disease. In my blog I have mention many different medicine as per the diseases and problems.
      You no need to buy all of them. The treatments are suggested as per the flower horn size and problems.

      You only buy those when is needed. Rid All can be preventing some of beginning diseases but not all.

      Keep informing about the your Flower Horn Fish so i can attain your query ASAP.

      Thanks for commenting,

      Thank you very much,

    1. Hi Aashna,

      You need to clean entire tank with warm water.

      Please buy Ocean free Gill, Fungus and Parasite special and once u cleaned tank u need to add five drop to it.

      If u have any decorative like pebbles or stones than remove it.

      And need full oxygen.

      Thanks for reading article and commenting.
