hitchhiker crab

[j_man]

It is nocturnal, about a cm across looks like a emerald but solid cream color. No visible eyes. hides in between my zoo polyps. when lights come on tries to bury himself in the polyps or moves under a very dark rock. anyone seen or heard of this?

It definitely sounds like a crab. Do you have a pic?

[josh_crosson]

i would try to get it out of there cause if i remember right they feed on zoos so do your best to remove it

It's always a good idea to remove unidentified crabs until you know exactly what your dealing with.
