What should I do?

[HermieLove19]

Mine like to push each other like wizkidsmom said. I think it has to do with the whole alpha crab thing.

Yea, usually when you introduce crabs, they have "feeler wars" to determine the "alpha" crab. Gilbert went straight for the climbing wall when I put him in so he didn't have a feeler war, so when GIlbert tried going into a cave of 2 sleeping crabs, Garth pushed him right out! So that got me a little worried, but now GIlbert has found his own space, when not climbing he rests on the branch between the vines peacefully.

I had the exact same problem. just let them bee, give them baths together.

There aren't any good places to get hermies here, so I won't be getting any more. But when I wanted to get another one, I would bring the ones that were up with me. I'd put the new one in the tank and if there were any problems (open claws, lunging, etc), the new one would go back. If they all ignored each other, than I got them.
