Hi Suraksha,
  The symptoms you describe can all be attributed to the ich infestation.  It takes a couple of weeks for ich to clear up even though it might appear to be gone sooner. It is important to keep doing regular water changes as often as you can.  Changing 25% every day would not be too much if at all possible.  Basically the situation with ich is this: it is a nasty disease but it is treatable if you get the medicine in there soon enough. Once the medicine is in there it takes several days for it to work (this is because the ich parasite goes through various stages, only one of which is vulnerable to the medicine).  During that time, the fish gets quite a bit weaker and so it is really a race to see if the fish can outlast the dying parasites.

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.
