Hmmm in my 55 general community I seem to have something going on. A few days ago I had one black neon tetra with a large belly. I isolated him in a floating breeder for observation for a while. I never saw any poop but, through his skin, I saw an out of place whitish lump. That night he died. So I went to remove him (lifted the floating breeder cage) as I went to grab him out of the breeder I barley touched his belly and it burst. There was normal poop colored stuff and then there was this white mush. I've since cleaned the floating breeder. I noticed a rasbora was getting chunky so I fasted the tank a full day and cut their feedings from two normal feedings a day to one smallish one. and I'm going to fast again today. Its been probably 3 days since the first death and now I have two rasboras, one neon tetra and one more black neon with chubbier than normal bellies. Everyone else is normal...
