He's moving a bit but not really struggling or anything.

There's about a half inch of space between the mesh and the wall. I've seen the crabs climbing up and down on it without a problem.JTKermie wrote:Have you had this crab and this setup for some time?
I would think as long as he has access in/out, all is well and it looks like you've got plastic mesh for that. It's hard to tell from the pic, but I'd try to avoid having the plastic mesh flat against the pool wall. I try to keep them set like ramps for easier in/out.
