From what I have read it eats algea.. I dont know anyhting more than that.. I have never seen it eating algea. Just crawling around on the rock and glass mostly at night..
The ones in my tank range in sizes from a dime to a 50 cents piece.. They are very slow movers and I have no Idea if they do any dammage.. If anyone knows where I can find more info on the let me know..
Have to give most all credit to Richard Rendos... One of the wisest people I know when it comes to reef tanks and creatures in them...
check his site out..

Really cool guy..
is the thing yellow and have like a white helmet? if so, i have a couple of them in my tank also. they seem to be good algae cleaners and don't bother a thing. its cool to watch their snout just move back and forth cleaning.

looks like a stomatella varia to me

"It is a small reef-safe herbivore. A nice grazer that will reproduce readily and will consume diatoms with gusto."
these guys are completely reef safe. they are a common hitchiker and you can get them with detrivore kits thats where i got mine. its pretty cool but when the lights go out i found about 10 little ones out on the glass
yep, like i said above that is what i have. mine are more yellow, with a brighter white helmet thing. mine seem to be growing quickly also, so i must have alot of funk they enjoy in my tank
