crab eating my waving hands

[evojoe67]

i just noticed a crab in my tank, eating my waving han coral. he's not like the other crabs in my tank who put stuff all over thier shells for desquise. i think it's the same one that is aggressive towards my fish as i swim by. i want to remove him, but can't catch him. any ideas?

find where its hiding, and take it out of the tank. make a hypersalinity solution and dip the rock, it should come running out.
