Weird slug snail nudi looking thing ID

[Thereefdoc]

A friend found these in the glass of her reef tank. She has seen a couple of them, also on the glass. The tank is empty, so no corals or fish inside. They did acquire this tank used and it was setup and running with LR fish and coral. Anyone have any idea what it could be?

Kinda hard to see. Are phots of the ones in the tank?

No they’re not in the tank. This is the best I could get her to send. Previous photos were much less clear.

I have some updated pics which are much better. It looks like some type of slug. I told her to observe it for a bit, see where it hangs and what it eats before deciding it’s fate.

Almoat looks like a faltworm or nudibranch. Most are bad. Does it have a shell?

I feel the same. Found these guys a few months ago. Apparently called chitons.

Yep chitons, good guys to have

Thank you everyone. I was leaning towards planaria as well. Her tank is fallow right now so it would be the perfect time to deal with them.
