I am sorry if these seems like a simple question :-/ I am pretty new to the betta world (or rather, the responsible, not putting them in a tiny fish bowl, betta world :) so I am trying to figure out what would cause bloat? I have been gone from Monday and returned today, and left a "7-day" betta food cube in the tank. My one fish, who does not like to eat pellets (unless he absolutely MUST) but will happily eat blood worms might have eaten a lot of the cube, or not, I can't be sure because it kind of disintegrates. I doubted that they ate anything, so I fed them about 5 pellets when I returned today and some blood worms. Later I noticed that one of the guys' stomach is larger than normal. Would this be because he ate so much food at once?? He is otherwise acting fine and swimming and flaring, etc., and when I put a couple of blood worms in again he gobbled them right up. Is there anything I should do/watch out for? The other guy, who ate almost as much, looks normal to me.
Thank you guys for your patience and help!
