No, mine is a regular Naso I "inherited" from my friend. It's the one I treated for ich with hypo for 4 weeks and now it's in my DT. It's always eaten a lot, just very picky on what it is. It won't touch formula 1 or 2 for example. But will eat mysis, emerald entree, angel formula and algae. Very weird that it has become best friends with my powder blue. Keeps following it around all over the tank and I was afraid they would fight.
