Acro Crab - sure can hide

[MikeP]

Yeah I have at least 4 in my tank. Two of them have moved into different colonies from the ones they came in on. But yes they do hide quite well. The last colony I bought had one that I saw in the store but upon investigation before placing it in the tank I found there were two living in that colony.
