Oscar Fish Care and Tips

 

 

 

OSCAROscar is one of best and hard fish, although Oscar Fish is not much first choice for any fish pet lover, but handling Oscar is quite easy and comfortable as compare to Flowerhorn fish. In this post I am going to explain you about all Care, Maintenance and treatment for Oscar Fish unlike the Flowerhorn Care and Maintenance

Let’s Understand Type of Oscar –

Oscar is originally known as  Astronotus ocellatus, is scientific name. Oscar is from cichlid family. Oscar is very aggressive fish with territory lover. Oscar love is live in community tank, making pair with Oscar – any breed. Oscar has many names such as OSCAR, TIGER OSCAR, VELVET OSCAR, and MARBLE CICHILD. Oscar’s natural resident is South America, but due to its beauty fish lover love to have it in Tank. And now worldwide Oscar is kept in tank.

Oscar Breed –

After the discovery of Oscar and fish lovers find the important about the Oscar – many breed are generated by doing cross breeding or some chemical changes. Red Oscar, Albino Oscar, Long Finned Oscar and many more are the example of these.

Feeding Oscar –

Unlike other Cichlid Oscar too love to eat anything you feed. Oscar eats every eatable in tank – even plants too. But you have to take precaution about this eating habit. As most of time feeding wrong food can take life of the fish. So here are Guideline for Feeding Oscar –

Cryfish, Flies, Crickets, and Grasshoppers are most used food for Oscar, as in pallet also made from these insects. Feeding Live Fish may hurt Oscar digesting system. Flesh and Beef heart, can be great source of Vitamins but also contribute to Fatty Liver Disease.

Live feeder fish such as goldfish and rosy red feeder minnows should not be fed, those fish contain an enzyme (thiaminase) within their flesh which binds vitamin B1, leading to deficiency.

Oscar love to eat fruits like Melons, Orange and other fruits. My Oscar is love to eat corn, sometime Mangos too.

Fish Tank for Oscar –

55 Gallon Tank (48x12x21 inches) is sufficient for Oscar. You can add Tank Mate for Oscar for breeding and life to each other Oscar, although Oscar never make water bad. They always keep tank clean and love to be clean.

You have to clean tank twice a week. Also maintained nitrates at a safe level. Oscar is bit tough fish can live in any water. But this cause to loose in appetite, color and health of fish.

Also once in month clean entire tank with warm water.

Oscar and Planted or Decorative Tank –

Oscar and plant is Bad Idea. As Oscar is great digger. They love to dig, plunk plant and change the set up. Oscar can eat plant so NEVER keep Oscar in planted tank.

Gravel or sand is good idea to make tank decorative. But Oscar will make self place to live and clean tank gravel and sand to make place to live. They love digging and do digging continuously. Always has medium size gravel so Oscar can play with that and some little amount of small size stone. You will love to see him doing all these.

Oscar Tank Mate –

Oscar can live in community tank with other fish. Even cross breeding also possible most of time. But don’t forgot Oscar is aggressive fish so you need to choose some aggressive fish with him like catfish or any Cichild. Keep in mind that both fish has same size.

Also need big size of tank to make proper community tank as Oscar is territory lover. So, minimum 4ft tank with One to two small cichlids (between 3-5 inches) or one medium cichlid (between 6-8 inches) is acceptable. Following is list of tank mate you can keep with Oscar –

  1. Hi I just got two parrot fish and two Oscar and one convict cichlid. Oscar fish is not aggressive at all however chiclid is one attacking my Oscar and Oscar doesn’t even gives back. Infact one Oscar was attack by this fish and injured badly even though the size of this fish is smaller than Oscar still Oscar is calm and not attacking any one in tank. What could that reason be.

    1. Hi Salim,

      Usually Oscar is settle with any other fish in community tank. If all fish is small in size than it take time to adjust but everyone is well grow than their is less chance to adjustment.
      I advice you to remove Chiclid and add another fish.

      Thank you,

      If other fish is eating and only one oscar is not eating means he is not happy with others.

  3. hi i have 1 pair of tiger oscars , can u tell me how many time should i suppose to feed my tiger oscars? size of my oscar fishis 3 inches. thanks in advance

    1. Hello Rahul More,

      Thanks for asking question here via comment. Their is no fix quantity to feed any fish. The condition to feed any fish is put pallet that fish can finish less than minutes. Follow this practice twice a day.

      You can observe that fish appetite getting increase day by day and eating food speed manner.

      Never let food remain on tank, that can pollute tank water. If fish is not eating within one minute than you need to redo process again they learn.

      Thank you,

    1. Hey Shashank,

      Extremely sorry for not replying on time.

      I guess the water is not suitable for Oscar. You need water conditioners for aquarium.

      You can use Oceanfree gill fungus parasites special to rid away whole in head.

      May be because of bad water condition non of them eating.

      Thank you,

    1. Hi Hari,

      The diseases you mentioned are indicating that water is not suitable for Oscar.

      You need oceanfree Gill fungus parasite Special for further treatment.

      First you need to either transfer Oscar to hospital tank or clean same tank.

      Now add two cap oceanfree Gill fungus parasite Special to tank.

      Install heater and increase the air speed. During course of treatment you should not use filter .

      Let me know if you have any further query.

      Thank You,

    1. Hello Sharook,

      By looking anal point you can identify gender of Oscar.

      Also two male won’t stay together. And it is difficult to identify the male female in small Oscar, Oscar need to be mature to identify this.

      Thank you,

      Yashwant Naik

    1. Hello Gokul,

      Well two feet is small because both fish can grow till more than five inch.

      So in future you may require big tank.

      Better you get it now.

      Thank you,

      Yashwant Naik

    1. Hi Any,

    1. Hi Manoj,

      Since now they are small than it can work but once they grow you need to buy new tank. Yeah Oscar is easily adjust with another partner buy make sure u have some female in team. As Oscar males are very egoistic. Can lead to fight.
