Thanks for the photo and answering Carlos' post. The information is quite helpful. In my opinion, there doesn't look like any indication of disease or injury. The body of the frog seems to be well-proportioned for a male. The biggest problem keeping this species is maintaining water quality. I don't see any husbandry problems.

From reading all the posts on this forum, bloating seems to be the most serious problem.

FYI - there are two kinds of bloat affecting ACFs. Hard bloat is caused by an internal bacterial infection. The skin on the frog becomes stiff as a board. This problem is nearly 100% fatal and treatment is difficult. Soft bloat is quite obvious, the frog taking on the appearance like the "Michelin man". This bloat is easier to cure using a combination of salt baths and antibiotics and the frog has a greater chance of survival.

At this moment in time, there is no need to worry. Keep up the good work. If your frog seems to be stressed out, cover the tank with brown wrapping paper for a few days and see if the frog settles down. Good luck
