Black wrasse
 

Hi all
Just a quick question, I purchased a black lepord wrasse on april 26th and have only seen it 4 times. My six line bosses the hell out of it when it comes and so it gos straight back under the sand. We found a piece of flesh with a vertebre attached so we figured it was the lepord wrasse. But just today who do i see? my leoprd wrasse flying around the tank looking pretty good. My question is how is he living? I've never seen him eat frozen so he must be eating pods at night i guess. I cant catch my 6 line so they have to work their problems out. My 6 line coexisted with a fairy, they was aggression at first but they settled down. I dont know exactly what to do.
thanks alot

oh and the vertebre turned out to be my watchman goby, have no clue how he died.
