This is my sitatuation. I have a 55 gallon tank fowlr. The current inhabitant is a snowflake eel. He has been in there for roughly a year and shows no outward symptoms of ick. When I first set-up the tank I had a few other fish in there with him all of which contracted ick and died. After leaving the tank fallow (except the eel) for 12 weeks, I introduced another few fish and all contracted ick and died. I waited four monhs and a few days ago introduced a lionfish. Again, ick and deah. My conclusion is that the eel is carrying the parasite asymptomatically. What would you fellows suggest as a course of action? I know copper based products are potentially deadly to eels, and I don't feel confident that a hypo saliniy treatment would completely rid the tank of the ick. I have nowhere else to put the eel atm. Opinions on a course of action would be welcomed.
