I was sure that this was a male for a while now. But I'm having second thoughts. I saw it on the back of a 100% known male the other day, but I assumed it was fighting. This is the largest auratus in the tank of 3 individuals. You can see from the first pic its girth has changed a lot since I got it, and it was not very fat at first. That was much of why I figured it was male. This girth change has happened in the past 3 weeks. The bottom 2 pics show the frog as it is currently. Any thoughts on sex?
