Mystery Slug

[KarlBob]

This slug hitchhiked into my tank approximately a month to six weeks ago. So far, I haven't caught it grazing on any of my zoanthids or corals, but I'd still like to know whether it's considered reef safe.

These pictures were taken in my tank.

These were taken in a 1 Cup measuring bowl.

Does this creature look familiar to anyone?

It's a stomatella with something growing on the shell. Oneof the most common hitch hikers and a beneficial grazer.

That's a beauty! I've never seen a red stomatella before.

I'm glad it's not a pest, because it is a fascinating critter. Next time I catch it, I'll try to figure out what's growing on its shell.
