    Hi,

    Found this dude in a bunch of Live Rock we were scrubbing today.

    Any ideas on what it is?

    Reef safe?

    Thanks for looking. ImageUploadedByTapatalk1373308536.516988.jpg

    Its a black emerald crab. Very beneficial as a cleanup crew member! I have an even larger one in my frag tank. Ive had it for about 2 years, & its never eaten any corals or fish!

    Does he eat Detritus or just Algea?
    Are you not worried he would eat all the small beneficial encrusting worms, pods etc?

    Ive seen mine eat algae & detritus. Definitely not eating beneficial creatures as i have more than enough pods & worms in the tank with him!
