Nudibranch ID help

[CMPS]

I've just purchased some coral and I found two of these hitchhikers. I'm hoping they are just reef-safe and algea eating nudibranches, but I'm not sure how likely that nice possibility is. Before I put the coral in my tank, what are these? Should I keep them or remove them?

@SlugSnorter @ISpeakForTheSeas, any help would be much appreciated! Thanks

It's a bit hard to see through the bag - do you have any top down shots of it not through a bag (preferably with somewhat brighter lighting)?

First thoughts from me without clearer pics would be either some kind of sea hare or sacoglossan slug (something like but not necessarily one of the following: Dolabrifera sp. or an Oxynoe sp. - both of which would be good).

Thanks for the reply, I'll take a clear shot as soon as I get home.

Here are the better shots from above

those are both beneficial…
but they’re not nudis, they’re stomatella snails.

Thanks for the identification! After a little further research, into the tank they go!

Agreed with ChiCity - those are stomatella snails.

looks like maybe a sea hare

edit: with second pics def stometella. Good cuc that can breed within your tank
