ID Snail...is it safe for reef tank?

[CarolinaVT]

I recently switched from cc to sugar fine sand. I installed some old powerheads that have spounges to clean up the cloudiness. About 2 days later, I went to remove the powerheads and found this in the middle while cleaning.
Is it safe for a tank with colt coral, zoas, and some fish?
Thanks

Looks like a stomatella snail. They are harmless and good cleaners.

wetwedmedia.com is a good source of information for stuff like that. They have pictures you can compare to, descriptions and all that.
I think its a Stoma too.

Thanks, I think it is too. I recall seeing something similar fall off my zoas when I bought them 6 months ago. A sea flea was also with it so I figured it would become fish food (I was nervous than too).

Surprised it made it through the substrate change and has grown this big.
