good point. I've been target feeding & it does go after it. It is becoming a little more curious & is roaming a little farther this evening. I plan on finding a new home for the damsels because they are breeding & making a mess in my tank with the sand they stir-up....sand everywhere! the 2 OSFF & yellowtail blenny are in a separate tank connected to my main system. If things don't work-out for him or her in 300, I could relocate to the 60 gl. where the filefish & blenny are. I really believe it will be OK & settle in when I find a new home for those crazy damsels. my plan is to catch them at feeding time one evening...hopefully I can catch 2 or 3 at one time?
