ID Help: pest or friendly slug/ nudibranch

[bice0004]

Ok need some help with this ID. I've seen a few in DT over last month. They are a slug like creature or nudibranch that is pink in color, with two little antenna and very small. About half the size of a grain of rice. I see them crawling over the live rock and not touching or bothering any corals so I think they are friendly. Anyone know what they are?

Elysia?

Maybe. I've never seen Elysia before so I couldn't say other than the link you sent. They are all pinkish with red dots. Also they are extremely small. 1mm max length. I had to use magnifying glass with iPhone zoomed all the way and then I cropped the image to get the pic.

Maybe the Vayssierea sp. in that same link?

Yeah that looks more like it. Thanks! Doesn't seem to be a bad pest then hopefully.

when im in doubt I kill it

I hear you but there isn't just one. I see them at different places in tank so I seriously doubt that I could find them all to kill them. Plus they are super small so hard to find them all.

If that's Elysia, it's a good thing.

I do think it is a nudibranch. Your photo is not clear enough to show which one and you don't show the face. Different nudibranchs eat different creatures--hydroids, sponges, anemones, other nudibranchs, jellyfish...can you post or email more photos and I can try to ID it for you? By the way, where did you find it--from which sea did it come?
