What to feed a tail spot blenny?

[Nicks0912]

Tried to feed him just now with fish food pellets but they were too big for the fish's mouth.
I notice him picking at the rocks constantly. Is there anything that I could feed him? Do I even need to feed him?

They require a lot of algae in their diet...I feed mine frozen formula 2, 2-3 times a week & he grazes on my LR for algae as well....

Mine chases after mysis that I feed my other fish, it will also pick at and scrape sinking pellets and wafers , otherwise it spends its time grazing on the on the rocks.
