Same with my blonde naso....That is one weired fish - will not have another one.
Just recently had a nice one in a big reef with very few fish. Everything was good for 4 months and all of a sudden it started getting spooked (changing color) and hiding in the corners...and completely stopped eating. It died after a week. All the other fish are fine even to this day.
I hear the slight Canadian accent and I'm just sitting here waiting for you to say "Soowry" in classical, polite Canadian form. In the video I gave myself a slight sauthern. Draul. Just to be silly. In.michigan and UK they say eh too.
