Janey is also eggy... So she becomes a balloon after being fed
Feeding well causes the fish to become more thick (no such thing as a fat betta)
Whereas you can see with my newest cambodian female, she is pretty thin... But her and a female crowntail I bought will thicken up with my heavy feeding schedule
Crowntails are notorious for having smaller stomachs. This guy, is proof
His belly is bigger than I would have wanted, but he'll be fine.
My super delta does not really show a belly. Would have helped if he stopped flaring at one of the male baby bettas and actually ate ALL his food.
My halfmoon shows a very small belly
Mickey always had a small belly, and shows it after eating.
