Can anyone sex my red claw crabs?
I apologize if this is super obvious, but I really can't tell what the crabs' underside should look like. I got these red claw crabs for my birthday and my friend didn't ask for their genders or anything, and I don't want to place two males together since I know they get really territorial, and I'm still in the process of setting up their larger tank (this was a big surprise and I wasn't prepared for it, haha).
Anyways, I've attached photos of both their undersides. If anyone is an expert or something, please help me out. Any input is appreciated honestly. I just want these crabs to be happy.
Also, I understand not to handle them this way, I was very gentle and only did so to snap a quick picture. They're fine now and just chilling out. :]
