What fish that will eat reef bugs?

[finless]

Is there such a fish?
I'm starting to see micro blue bug type things on the rock.
I have a bunch of sps I want to protect.
Any suggs. and something small.
Clingfish?

Sure they're not white bugs? The white ones are copepods, friendlies, that eat nuisance algae and phyto. Most fish will not turn one down, but scooter "blennies" and mandarins specialize in them.

I've got plenty of those.
These are like neon blue and so small I didnt know they were buggish until one moved.
Hope there not the killer nudibranch.
