I have a RES approx. 6in. in length. I think it's a male. I've seen him pass small river rocks before with no problem. today I noticed he was at the bottom of the aquarimium and it looked like he was having a very big black bowel movement. It can out approx. a 1/2 in. and blossomed out but then went back in!! Is this his male organ or is he trying to pass a big rock? He hasn't ate today but otherwise seems fine. He's still doing his mating dance to my other slightly smaller RES. Does anybody know whats going on here? Please help!
