    I finally got a picture of one of my crabs, seem like there are a few of them in my tank, I think they are all the same species.
    From what I have heard the problem with them is they eat the live rock.
    How much of a problem are they?

    Never trusted furry craps with sharp pincers, cool when they are small, but can cause havock in your aquarium as they grow bigger. Ask me I know.:(

    No keen on killing anything (except aiptasia) I would banish him to the sump. Be warned though, I had one in my first sump that grew large enough to chop right through skimmer pump cable=dead short = cant fix cable = R2000 for new pump....

    Itsa tough choice, but keeping them in tank could have them catching expensie fishy meals too.
