| so I was watching my hermits cleaning the tank this evening as they normally do, and I see a claw coming out from a hole in one of my rocks, I thought it was one of them out of its shell, but all 4 were in shells around the tank. After a bit more watching, it looks like I might have had a very small Emerald Crab as a hitchhiker. I'm waiting for the lights to go out to see if he comes out anymore. |
