Friday I added a yellow headed jawfish and it likes to hide. I don't have a agressive tank, just some agressive swimmers (Coral Beauty - Sleeper Gobie). I can't seem to get him to come out to eat. Do I just need to be patient and he'll come around? He might come out when I got to work but when I come home there's no sign of him except for some beady little eyes looking out from under his rock. I just hate knowing I have a fish in my tank that's not eating. Any Suggestions?
