    Usually ok but some have been known to breed to pest numbers and nip corals

    I have a number of those and they are munching my zoas. I would not add them.

    I have seen a couple of them in my tank. I did not deliberately add them. I actually remove these two this morning.

    Jip, little hitchiker's. At one stage I had hundreds of them in my tank. They have a way of getting into he powerheads, chopping them up, yhen the bits grows into many more provided there are enough food for them. Apparently harlequin shrimp will eat them. I got mine under control by manual removal and algae comtrol
