The Spider Decorator Crab, Camposcia retusa, is a slow-moving scavenger that curiously attaches various anemones, sea flora, sponges, bryozoans, and coral polyps to its exoskelton in an attempt to camouflage itself. They are semi-aggressive and can harm smaller crabs or snails. Though generally stationary, it will move to eat and breed. The Decorator Crab is easy to maintain and thrives best in well-established reef tanks with a thick sandy bottom. 

This Crab/Spider is a very good thing I do recommend getting a lot of coral and placing a bunch of things into your tank though because this crab will take anything it can find and pickup then put it on the shell.

Very cool crab! Love watching him "decorate " himself. This crab will give you lots of pleasure as he crawls about your tank

The only reason I got this crab was because Saltwater Fish called to tell me the original crab I ordered wasn't "up to par" and was asked if I would like this type as a replacement. I'M SO GLAD I DID! This is the coolest crab! It looked like a big "blonde " tarantula. Then one day it suddenly looked like a skeleton! I thought it had died until it started moving. Was fun to watch it re-decorate itself. Highly recommend this guy
