Gall Crab

[rlcline76]

It appears that my new brain has a gall crab living where a polyp should be. Although very interesting, I am keeping an eye on it. I know wetwebmedia advises keeping 95% of all hitchhikers, but if this guy exhibits any further activity that I believe will have a deleterious effect onmy coral, his tookus will have to go. Anyone know how to safely extract one of these?

Gall crabs are often associated with acropora stony corals. They don't have any negative ramifications in living withi the corals skeletal and tissue structure.
