[Anero]

I found this nudi tonight, any ideas if it is good or bad?

sorry for the bad picture still learning and I need new lenses

Looks like a Monti eating nudibrach.

I have no Monti or SPS at all, should i be worried about him??

He doesn't look like a monti eating nudi. I'm sorry I can't provide a better ID, but monti eating nudis are absolutely tiny.

It's an aeolid nudibranch of some type. They're almost all very similar in appearance, but getting a better ID is basically irrelevant because all are predators of cnidarians. Chances of it being a desirable inhabitant are very slim.

That's an assumption and it could be a predator of any number of things. From what I can make out it doesn't strike me as a typical zoanthid eating nudibranch and I'd lean toward an anemone or octocoral predator of some type. However, I certainly wouldn't rule out the possibility of it being an aeolid that favors zoanthids.

Anero, remove it and keep an eye out for others. Though if it has been traveling around the tank, odds are whatever it's favorite snack is, you don't have it. As for predators... Wrasses of the genus Halichoeres sp. will often seek out and eat aeolid nudibranchs.

when in doubt, i would remove....

I agree with both of the two postings above as well as with greenbean36191. Nudibranchs are specialized feeders; if you have what they eat, they will eat it until there is none and then perish.
