Random slug type creature

[Zach Sonker]

Hello. In my 15 gal I randomly had this critter pop up... the tank has been running for a good 3 or 4 months now with minimal additions. I have 2 clowns a tiny scooter and a tiny Goby. All fish have been in for months as well as rocks and coral... so this critter has been living secretly in the tank for awhile. Anyone know what it is? I have 3 trocus snails also. But this looks nothing like them. Almost like a skinny slug or flat worm.

There may be a thin small plate like shell on it... it is very hard to see it's in the back corner behind my live rock where I like to let the pods stay with a little algae. It doesn't move much and this is the first time I've ever seen it.

It definitely has the same mouth facial features though

Stomatella, they're beneficial

If it's a stomatella I like them and they are welcome in all of my aquariums. The shell can be hard to see but if you get close to it the animal should withdraw into it.
