Turbo snails eating coraline algae??

[XtremeFromHell]

ugh.. i think my turbo snails are eating coraline, my over flow box has a bunch of coraline and one of the turbos is on it and i noticed some areas missing coraline algae, also my other turbo has been grazing on one small rock since i bought him and has not moved from that rock and it kinda seems to me that the rock is a little whitish around where he is, can they actually eat off coraline?

No, their radulas aren't calcified, so they're softer than the coralline and useless in scraping it off. They can knock off bits that are otherwise loose, but that's about it.
