Mine would but not much and frankly I do not feed flakes very often. When we bought this house I lucked out and bought a Refer they had in the basement (where all but 1 of my tanks are) so I choose to keep lots of frozen foods and find my fish seem happier eating the variety I offer. I do find tho when I do give some flake (Prime Reef mainly) the Angels and Butterfly and yes the Triggers seem to like it well enough. Alas most of my other fish are spoiled now and give me the evil eye when I try it.
