My rasbora died just today. His stomach was enlarged and he could not swim properly (swimming became an issue on the second day). I gave him peas as to help with digestion but he wouldn't eat. Later tonight I came upstairs to my room to see that he had died and my betta was eating his eyes. I fished him out. Upon further examination, I realized that the poor little guy's stomach had exploded. Naturally, I buried him after taking pictures for examination at a later time. Does anyone know if this was disease/parasite related or was he just bloated?
