Recently, one of our phoenix rasboras (cousin of chili rasbora) is getting a little round in the belly. Is it pregnant (or the more technical term is gravid)?
We are not very sure, will ask in a forum soon afterwards. Possible alternative reasons is that it is bloated, overfed or even dropsy!
From our experience, it is better that the phoenix rasbora is fat rather than thin. A thin rasbora signals a possible internal parasite problem, which proves to be fatal for this small rasbora species in our experience.
