Thanks, He gets to stay then. Just spent the night changing the rock and taking out the niger trigger and damsel. The trigger tried to get the crab a couple times but that crab is fast. The trigger is heading for the LFS for a store credit. He was going to be risky anyways when I start putting corals in. The damsel was just plain mean. Attached the blue tang that was just added to the tank constantly. Thanks for the help everyone.
