Copper band will eat them but he also like feather dusters and might nip at clams.mine did.

6 Line Wrasse will eat them pretty fast! Emerald Crabs work too but I have had Emerald Crabs eat the odd coral as well.

I have seen my banded shrimp eating them as well..

I saw my arrow crab eat a few. But a Bristle worm trap works really well. I have the green tube one. Just set it down where you see the worms. Then turn off the lights and in about 1hr you should have caught a few.
