Fish/Popeye treament for my Flowerhorn.


Good day sir. I am Conrad and I own a Flowerhorn for 3 years. This last week my fish had 1 popeye. I immediately ask a flowerhorn expert and he told me that I should buy MELAFIX as treatment for the fish. His instruction was change 25% of water of my tank and to put 7 caps pf Melafix (API Dosing cap bottle with melafix on it) everyday for 7 days. Right now I'm on my 6th day of treatment and to my surprise tonight I saw my fish have 2 pop eyes already. I don't know what to do anymore. Please help me sir. I don't want to loose my flower horn. Hope you could help me.

Thank You.


Hi Conrad,
  Unfortunately there is not much I can offer.  Popeye is a serious disease and I have never had any success treating it. Sorry.

I am an expert on cichlid fishes, particularly New World cichlids. My broader expertise includes the behavior, ecology and reproduction of fishes in general. (I am NOT an expert on Goldfish). Please do not use abbreviations, such as "my GT has a swollen eye" because I don't know what a "GT" is. The more clearly you can explain your question, the better chance I have of understanding what it is that you seek. I keep fishes both as a scientist and as a hobbyist and I currently maintain about 140 aquariums.


I am an Associate Professor at the California State University, Sacramento in the Department of Biological Sciences, and I run a website, called the Cichlid Research Home Page . I also write for many popular aquarist magazines, and I was editor of Cichlid News magazine for several years. I am a scientist and I spend my time teaching fish biology, ecology, behavior and evolution and doing research on the reproductive biology of fishes, particularly cichlids. I do research in the laboratory and in Costa Rica, Nicaragua and Mexico. My main interest is understanding the evolution of parental care in fishes. I am interested in encouraging greater public awareness, understanding and participation in science.
