This is a brand new fish and his stomach was bloated when he was added to the tank. The temp is always between 78-82 because I use the overhead light 10-12 hours per day. I did purchase a heater but never used it based on issues I have read about when using a heater on this small of a tank.
In any case, none of the tank conditions should be a factor since he was bloated straight from the store. And since I did't feed him anything other than a pea so far, the food isn't isn't any issue (but i appreciate the feeback on soaking free dried food).
The real question is, should a crown tail Betta have a stomach that looks like this or should I be concerned? And if I should be concerned, should I be doing something other than feeding peas?
