I believe that they are considered reef safe. I had one for a short while but it dissapeared (lol).

Like all crabs, they are an opportunistic feeder. If the opportunity presents itself, it will take full advantage of this. For example, if a snail flips over on it's back, an invertebrate molts, or a fish is sick but still clinging to life, it will begin to feed on this. It isn't often that it actually picks on corals and coral-like invertebrates. I would consider it Reef Safe with High Caution.
