What eats Coraline algae other than urchins?

[Delphinus]

There was one at J&L about a week ago. Not listed anymore though .. might be worth shooting off an email to them plus the usual local suspects too although I can't say that's ever worked for me (best way to ensure something never comes in is to ask for it.. at least in my universe )

had some chiton hitchhikers, never noticed them eating the coraline. If they were, wasn't to the bare rock like urchins.

There is some reef safe parrot fish. My LFS (raging reef) had a few of them in his SPS tank and they were constantly eating coralline algae.
