    Hi guys

    I have recently moved into the world of keeping SPS but upon buying some new frags, I have noticed crabs resting between the coral. Should we leave these crabs or remove them?

    If they stay in the SPS day and night, then most likely they are beneficial. Baddies will hide away during the day in the rock work.

    But as they say, a picture says a thousand word.

    Do they have a black stripe from eye to eye?

    Maybe (Trapezia guttata) Spot-legged Coral Crab?

    You have to ask your self a question. Is the crab damaging the coral. Don't blame the crab for top up or bottom down STN.

    You have to observe the crab and what it is doing to a stable SPS environment. To often we see crabs being blamed for all sorts of things, when they are actually removing the algae and undesirables from the coral.

    I agree,i even take sps crabs from the wild to put in with my non crab corals to protect them and keep them clean of bacterial issues and fight off fish that have a go at the corals.
