Interesting, I've been under the impression, from material I've read, they are strictly herbivorous. Looks like I will be doing some extra homework tonight. I also keep nassarius snails so the oppurtunistic part doesn't worry me. Every fish, snail, crab, anemone, and coral are opportunistic to some degree and I've almost given up on stereotyping any creature.

I agree that stirring the bed is still warranted. Nothing beats good old fashioned "shoulders-deep in water" tank maintenance. However, I am still loving the fact that I'm stirring sand because I want to and not because I am looking at hideous brown algae LOL!
