Just want some info on this fish, i've heard real good things about them. Anyone that has had one care to give any tips or info on it? I ordered one from this site last week and he should come on Tuesday. I have live rock with some nice holes/caves in them where he can hide. Does this fish hide most of the time? do they ever come out and swim around? What should I feed him first? maybe some brine? mysis? thanks for any info!
