    image.jpg So I occasionally check my tank at night, I generally just see stomatella snails, but this time I found a brittle star! No idea how he got in my tank, and I don't know much about these guys. So as the title states, is he good or bad? Thanks!

    I believe all brittle stars are fine. I bought mine. It's probably a foot across now if it stretched its legs all the way out.

    Got some 'micro' brittles as hitchhikers, and they are supposed to stay small and be a beneficial part of the CUC

    Beneficial. That's what's typically called a harlequin brittlestar there. They're micro brittles as William mentioned and they don't get very large. I have tens of them in the tank since I feed pretty heavy and they're decent general scavengers. I even have a couple of the large red brittles, on of which stretches an easy 6" across, and they're reef safe (unlike the green ones).
