Good Crab ,Bad Crab?

my 75gal reef tank has been running for 4 months now and last night i saw a bright red crab. What is it? Is it bad?

depending on what else you have in there.... try catching him and putting him in a seperate tank ..... he could be a killer!!! or when you get him bring him to the local fish dude and give him a new home!!!
