Tiny snail ID Please

[elic173]

I saw this on my glass, it's tiny about 1mm

The pic is through a magnifying glass and the snail is in one droplet of water.

Anyone up for the ID Challenge?

Pretty hard to see. Based on the size I’m going to say collonista snail.

Wow that impressive. Good skips!! I googled them and this is them!

Do you know much about them? Are they reef safe? I watched it burrow into the sand.

They are reef safe but they can multiply quickly under the right conditions and that can be annoying.
