We’ve had one for at least six months. Only comes out at feeding time whether it’s dat or night. It hasn’t bothered anything and my snails breed like crazy. I wish it would eat the dangled bristle worms but it prefers the DIY “reef chili” we make fresh. I will say it’s scared of the fish or anything else that moves. I have a yellow kole eye tang that likes to hang out at the entrance of the lobster’s cave and the lobster is more afraid of the fish. It has grown a lot since we got it. I do wish it weren’t so reclusive because it’s pretty cool lookingThank you guys for the input. This was very helpful. We'll see if there's anyone who has conflicting experience, but if this is more or less the consensus on the thread, I'll be getting some clownfish soon. ^^
