It is! It's a juvenile Chrysurus... I have been looking for this fish ever since i got into the hobby years ago, and finally found this super healthy Juvi.
It was a real bummer to find out he was nipping the zoas... whats worse is he was fine up until introduced a colony of Utter Chaos and Rastas last night...
Not sure what happened, but after putting in the new Zoas, he went straight for the old existing colony!
I am on the fence... I am looking at FOWLR options now for him... i never see them for sale and don't want to give this guy up!
