I recently purchased an arrow crab to help with my bristle worm "infestation"...it's worked like a charm. However, the rascal just molted and as it's my first crab, I'm trying to decide what to do with it. I've read on here, and the general consensus seems to be to leave them in and allow other inhabitants eat it. As I only have two other fish, a yellow tang (4.5") and a percula clown (3"), do you guys still feel that's the best thing to do? I'm working on bringing my nitrates down (overfeeding from previous owner), and don't want to aggrivate the problem... perhaps that's a non-issue with the "molt"...?
These may be a silly questions to some, but I just don't know and need to ask!
