I just lost most of the fish in my tank to ich, which had become very advanced before I understood what it was. There are only two fish remaining in my 20 gallon: a dalmation molly and a fancy guppy. This is the 10th day of treatment with medication, but their lesions look worse than ever. They are still spending lots of time on the bottom and top of the tank. Until yesterday, there were three survivors, rather than two- one of my glofish was found dead this morning. The glofish had been getting a large belly and I assumed it was from the parasites. Today I discovered fry in the tank! It seems the glofish was pregnant, although I was assured at the LFS that I was given all males. Now I have plenty of questions. Were these babes born with ich? Is the medication toxic to them? How about the toxicity of a tank in which the filter has not been running during the medication period? Does it seem that the other two fish are doomed? I do not have a proper hospital tank, and would like to keep the babies in the tank I have if the other two are not to survive. For the time being, the fry are segregated to keep them away from the guppy. I was in no way prepared for babies in a tank of "males".
