My friend just gave up on the hobby and gave me a cool little fish,he said it was a yellow headed jawfish.Iput him in my refugium for now till i got some info from the forum.he seems pretty docile.he just makes a little cave under the lr and sits with his head poking out.once in a while he'll come out and take a little swim then goes home.he eats well and has excellent color.My q is will he be ok in my 55 reef.He wont bother none of the cleaners or shrimp?any inf will be helpful.Thanks guys!!
