Last Summer while I was home from college, one of my fish had a serious case of SBD and nearly died. He made a complete recovery, except for the fact that he now seems prone to very mild cases, so I've had to be very careful with how much I feed him and his water temperature.
Yesterday I moved back home, and he almost immediately became very bloated again. I know we have different additives in the water here than at college, so I'm wondering if that could cause the problem? If it does, what should I do about that? Would finding a new brand of water conditioner make a difference? Or do I need to get him distilled water?
PS. Another thing- I noticed that after I set up the tanks last night, there were little bubbles sticking to the plastic plants and the heaters and all the toys. We're wondering if maybe because of the bubbles, he swallowed too much air and that's what's causing the bloating. Does that seem more likely?
