I believe this pic. explains why my pipe coral isn't doing well :twised:

Time for crab concentration camp... or off to a healthy trigger tank me thinks :lol:.

He is basically the only crab I have in that tank (I call him big claw) and he is pretty large. I did put him in my fowlr tank for a few days but then felt bad for him as he was hiding in his shell a lot and getting picked on, so back into the reef tank he went. The pipe coral is pretty fragile so I think he's breaking it when he walks on it and that's why it's not doing too good. He doesn't seem to bother the other corals.
