Yeah, AQ salt can actually make bloating worse, but it's good to have for external problems such as what Larsa had listed.
Cute boys you have, Fishie will become beautiful once he is at full health.
The only thing that is concerning me some is that his belly is pine coning (Epsom will help that too), and it looks as if he is missing a lot of scales around his head area.. is it just his coloring, or is there no scales there? As well as he looks as if he is blind or partially blind.. notice him not seeing your finger or food sometimes? It might explain why he swims with that side to the glass, as he feels secure on that side with something constantly there, and he can see the inside of the tank with his good eye.. something to consider. If he is partially blind, he will still live a happy, healthy life once recovered.
