Nudibranch id please

I can't get a great picture but can anyone help with this one? It's super tiny maybe 1-2mm

Hmm i could be wrong but i would say,

Berghia Nudibranch - Aiptasia eater only

These will find and demolish Aiptasia's if you have any but they have a short lifespan either way. Was this a hitchhiker?

Later days,

Yeah it was a hitchhiker on LR from Gulf Live Rock.

I've had something like that come in. The closest match I found for species was a hydroid-eater.

Generally, a nudibranch with those projections on its back is one that eats some sort of stinging sessile invertebrate (corals, anemones, etc), and they tend to be fairly specialized. Like how you wouldn't find an orchid-eating caterpillar on an ivy plant, you aren't likely to find, say, a zoanthid-eating nudibranch on Gulf rock with no zoanthids.

It's probably not a concern.

I already sucked him out in a specimen container, haven't been able to get a better shot of him yet.

I would hate to have coral eating nudis, but then again where there's one there's probably more.

It's eating something that came in on your live rock. If that something is, say, hydroids, you're good; nudibranchs tend to be specialists. A hydroid-eating nudibranch won't touch our corals.
