What eats this?

[Mohacks]

Is there any kind of critter that I can add to my tank to graze on Suction cup Caulerpa algae? It came in on some live rock when I set up the tank about 6 months ago and wasn't a problem until I upgraded my lighting to a T5 system and it is now exploding everywhere and is impossible to pick out.

36 gallon bow, 2 clowns, 2 pajama cardinals, 2 purple fire fish, numerous small hermits, 2 turbo snails, 2 fire shrimp and one very shy anenome.

You could try a tuxedo sea urchin. It'll at least pull the stuff up, if not eat it. They feel kind of like a stiff hairbrush, they really aren't spiny at all. Maximum size is slightly over 2" long in huge tanks, and they come in plenty of colors. They will pick small things up and haul them around, which can be slightly annoying with small coral frags.
