Hi , My flowerhorn is really unwell.  The local fish shop guys have given me various things to try on but nothing has helped.  She is getting worst by the day,  Have used rid all with absant salt for 3 to 5 days , go on to metronidazole tablets , and than to metrogyl and on and on ….  In btw I got feed up of giving him so much medication one after the other that I stopped stressing her.    – currently she is lying on the bottom of the tank , there is a layer on the eye … Which showed some improvement.. she was eating food only when feed close to mouth .. now has started eating a little and throwing out rest.  Tank is 20 – 21 inches – 18 inches …  Please I desperately need correct guidance.
