Well, one of my axies is looking pretty fat these days. I don't know if it's male or female. His/her stomach is becoming wider than his/her head. It never used to be that fat, and I haven't been feeding it any more than usual. It's about 9 months old, and I have it in a tank with two others, one of the same size & age and one slightly smaller & a few months younger. I have no idea if it's eggs or what, but that's just my shot in the dark. It could be nothing, but I just want to check. I'm kind of a noob when it comes to these things. I mean, I know well enough how to take care of them and everything, but gender, breeding, and all that... not a clue.
