Anyone know what kind of nudi this is? :confused: Found it crawling across my front glass this morning. Its about 2-3mm long. Not sure where it came from, I haven't added any corals or rock recently. The only other nudi in the tank is a lettuce nudi. The other specs on the glass are copepods. I have had an explosion of them in my tank recently because my mandarin died. :(

Anyone? I know there has to be a nudibranch expert or two on here. :bounce3:

I'm not sure there's anyone on here expert enough to identify it for you. A lot of the aeolids look alike, and there are apparently plenty of them that don't have names, as well. Chances are they are feeding on one of your species of corals or zoanthids. If you search around for the area where they are concentrated, you should be able to narrow down the food source pretty quickly.

Here is a pic of the nudibranch with the MH's on. I haven't noticed any of the corals being eaten but this guy just showed up today so we will see. I was hoping that it was a beneficial species like the lettuce nudibranch that I have.

Does anyone have any pics of known :uzi: coral eating nudi's?

Here is a popular one that eats "corals."

I read some articles about this species of nudibranch and it does look very similar but they don't mention anything about them eating corals. Some websites are advertising them as aiptasia anemone control. I emailed a few pics to the Sea Slug Forum (Austrailian Museum) hoping that they can identify it. Thank you for your response.

I found this article on them: http://www.reefkeeping.com/issues/2004-01/ac/feature/index.php

Any new news on these guys? I have pulled several out of my tanks thinking they were the ones that chowed down on zoas.

The first set of photos appears that the nudibranch has algae chloroplasts within its tissue and the overall shape/size of the nudi has me guessing that it could be Placida dendritica. I have a few photos within the snail section (scroll down) of my hitch hiker pages (http://www.chucksaddiction.com/hitchhikers.html) if you wish to compare.

Sorry, I didn't have much time to post and didn't get my intended point across.

All I intended to convey was that they are numerous nudis that feed on coral. If you are interested in the food species of nudis, I suggest the following resource: http://people.ucsc.edu/~mcduck/nudifood.htm

Just an update: I ended up finding 3 of them in my tank and have removed all of them. I also found what I believe to be nudi eggs on a frag of Zoos that I also removed.

just found a bunch of these nudis eating my zoos. does any have any tips for getting rid of them. manually picking them all out doesn't really seem a good option for me since there are dozens.

I think there are a few animals that you can get that will eat them.

Perhaps one of these:

They are listed as eating the montipora eating nudibranches, perhaps they will eat the zoo eating ones also.

:sad2: Okay, this is a good example of poor identification by a LFS with bad consequences for the purchaser. The animal in the photo is a dorid nudibranch. Dorids are sponge eaters so it's diet is restricted to one or a few related sponge species. THIS is a true Navanax inermis http://seaslugforum.net/navainer.htm and it's an eastern Pacific temperate species. If you bought the one in the photo you'd be out $25 plus shipping and it wouldn't do a darn thing to help. It would just starve to death. The Navanax is a sand dweller and would concentrate on whatever sand-dwelling snails you have;it might not go up into your corals at all.

Sorry, I know very little about fish. Inverts are my thing. I was hoping someone else would add something about the fish. Maybe you could post in a fish forum & ask.
