I picked up a pink square anthias from my lfs 2 days ago he was active at the lfs but i have recently put him in the tank and he has been hiding in the rocks ever since. I have a brown clown and a porcelan crab in the tank and nothing else not sure whats going on. I have fed them mysis shrimp, bloodworms, marine flakes, and brine shrimp and still no movement.
