I've had this fish for acouple weeks now and have gotten rid of most his body fungus patches, they were small and quickly disappeared with Maroxy and Maracyn.
But, he still has this bump on his side that looks like it's solid. I can't seem to get rid of it, though i've only tried 3 different types of medication on it (not at the same time of course). Maroxy, Maracyn and API Fungus Cure. I just started him on some Maracide today.
Previously he was in a 1 gallon QT with an undergravel filter. I was doing partial water changes every other day. Yesterday I put him in a 1 gallon Diamond QT with no undergravel filter but with an airstone to keep the water moving. I have him half a capfull of Maracide today.
He eats (though he's a picky eater) and swims around fine. He doesn't act like he itches or like anything is bothering him. I've had him for maybe 3 weeks now.
