Posted before I type in the info. When I got this fish at the end of April, his belly was a little sunken. I treated with 3 rounds of PraziPro, fed Metro, feed food with Epsom salt. Dosed three rounds of Levamisole. It got much better and belly was flat. However, it started to sunken again. Other fish in the tank are ok and no one bully him. No damage. He still eats buy not eagerly. Swims around and follows me around. Please help and tell me what else I can try.

Thanks in advance.

Feed some hex shield and redose levamisole.

Ok, do I redose the entire tank or isolate him only?
