I have always used a little salt in the tank, as I have a "fresh water" moray eel in the tank with them. Also, a couple of days ago I found out that my son had turned the temp up on the tank. So in a round about way I have already done those things. I have looked pretty hard at the fish to see if I could see any white spots on the fish, the only thing I have seen was on the Texas, and it was more of a white patch by its tail fin. Do you think I could try a ick med or is it most likely something else, seeing as I have tried 90deg and always add 1 Tbl to 5gal at h2o changes? thank you for reply's.
