I ordered 5 hoplo catfish from lfs, maybe mistake number one. One looked like he had not eaten in a month..took the other 4. Now, two of them have ick, one has serious fin rot , one may be ok. I'm addressing ick problem mainly..I don't think I can save third with rot. But will take advice on that too. I have had success with Coppersafe with other fish, but I know catfish can(are) be sensitive to most medications. Ick showed up this morning, about two days after I brought them home. There is half dozen neon tetra, an angelfish, and a bristlenose pleco in 40 gallon breeder with two hoplos about 3/4 inch long. Don't know what to do. I do have metro crystal on hand.
