I was looking in the tank with a flash light and saw a small hairy yellowish green crab about the size of the dime. It was on some branch rock covered in green star polyps. It tore off a strip of green star polyps and was carrying it around. I immediately tried to catch it but was unable. Any ideas???

What color are the claws and are they pointy?

Could be a decorator crab of sorts because they like to put corals and similar items on themselves, they actually help the propagation of corals in the aquarium! I've been actually wanting a few!

I was unable to see the claws due to angle and it doesnt have the shape of a decorator crab of looked more along the lines of am emerald crab

If it is ripping off coral, it is probably bad.

Something has slowly killed off all xenia and daisy polyps over the last 2 months im now suspecting it was this crab
