Help ID this nudibranch?

I found two of these in the tank yesterday. Both about 0.5cm long. Looks like lettuce nudibranch, but I'm not certain.

any chance you can get a better picture? Almost looks like an amphipod in that picture.

Do you think it came in on live rock? Where is the material that you think it came into the tank from?

It doesn't look like a nudibranch. It looks more like a sacoglossan, possibly Elysia (the same genus as lettuce slugs). You'll need to get a better picture to tell.

Looks to be an Elysia species, but I can't tell which one without a larger pic.

Cheers,

Lookup arminid nudibranch. If you have clove polyps in your tank, then it's most likely it. It's pretty common for these guys to sneak into systems attached to the cloves. Not a good hitchicker, diet consist of softies. Goodluck with the id

Not an arminid, not with a head like that and the parapodial bulge. Elysia was also my first thought when I saw the picture; my second was I need a better picture to be sure.

Picture was so far out, can't get to good a look. Here's a pic I took, blurry, but you should be able to compare some of the features.
