I just got a LB today from saltwaterfish.com with some other fish and inverts. Been watching them closely. The LB has been hiding in this one spot and now I can't see him at all. Did a pretty thorough search a few times in the whole tank, no sign of him. Don't see him on the floor or behind the tank and the overflow is hard to check without removing the light fixture. So, are they jumpers at all?
