Zoo eating nudibranch?

I think that this little may be a zoa eating nudibranch, looked at the pic from the sticky on this site. Wanted confirmation and to know if it is good or bad,and if bad, what I should do about it? Thank

 

a little more info, it seems to be acting like a snail and just slowly moving around my glass eating the alage. Looks like it has a mouth similar to a snail

 

Sounds like a NB, did you try googling it? Luna

 

yea, im doing that right now

 

If it is, GET IT OUT ASAP, if you love/have corals. Luna

 

I did, I just know that if there is one, then there are more, ill keep an eye out for them

 

Nudibranches eat more then just corals. They also usually turn the color of whatever they are eating. From the looks of your bubble coral, it might be eating on that. If you have one, you probally have hundreds of them. Ive dealt with all kinds of nudi's. Theres lots of dips that kill them, but not their eggs. Only one kills the eggs that I know of, but you seriously risk killing your corals too, and thats if you can get your hands on the stuff to do it.

 

Pretty sure it's a polyp eating nudibranch. If you have polyps also look for eggs and do a dip on all polyps. If you don't have polyps remove it anyway. There is a Bergia Nudibranch that look similar but eats aiptasia.

 

If you have zoanthids, if you see some polyps closed up, thats a good place to look. For that matter, if you any coral closed up or part of it, look it over.

 

From my experience, that doesnt look like a zoa eating nudi, looks more like a monti eating nudi. Hard to tell for sure in those pics. But like I said earlier, not all nudi's eat corals, some just eat algae. but like I say, when in doubt, pull it out!
