I believe all sizes eat FA. The little ones get big, and the big ones get bigger, on algae (and what fish food they can swipe from the fringes of the feeding area).

Every big Tilapia I have ever cleaned (I remove in mid-September onward) has had intestines full of FA. I have only cleaned a couple YOY; they were full of FA too.
