Hi guys, just wondering what this nudi is. Should I take him out. As for a size referance that is a monti polyp top right, and a tiny sponge to the left of him. I estimate him to be about 8mm long.. Any ideas?

With something like 235+ genus and goodness knows how many species, you want us to identify a nudibranch :rolleyes

 

[brendore]

Yes, yes I know:rolleyes , but I was thinking if maybe someone has had one like this they could shed a little light on it.. I know there are some that are not good in a reef tank, but so far (knock on wood) this one hasn't seemed to have caused any problems. And he is quite a good looking thing if I do say so :D

If you don't want him I'll have him, he can tackle my apistia

I'd like to keep him that's for sure! :D I only get to see him about twice a month :(

My best guess would be Hypselodoris obscura (Obscure Nudibranch). THis species feeds on sponges and retains toxins within their tissue as a defense (thus their colouration).

Thanks doc, looks very similar to the one I have. Lucky I have a tonne of self propagating sponges :)

 

[mscott]

from what I've heard elsewhere its quite hard to get any of them in aus, you should feel lucky lol, it would be cool to see how this guy goes :cool:

 

[Dr. Schell]

Nudies are notoriously difficult to keep alive for any length of time in Aquariums. Up here (QLD) they are very common on mud-flats and on rocky shores. At certian times of year (during the mating period), they are one of the most obvious and abundant invertebrates.

I'm guessing he's probably come in on some macro I've collected locally. My tank has been running for 9 months and I didn't see/notice him before I added the macro. I've seen a few nudi's that go to lfs' when I was working for CM, the most common being the fluro or toxic yellow ones (Notodorris gardineri), but nothing of this colour :) I'm hoping he does well!

 

[mscott]

thats rele cool, well if anyone can point one of the apistia eating ones in my direction i would be much obliged, and so would it haha :D

We get nudi explosions here as well, usually washed up on the beaches after any swell. The ones I've found are a very steely blue above and white below with large "wings" (I'm assuming they might be pelagic, or at that stage in their life cycle?)

Thorunna florens ??

It didn't help me much but this can be a good site to identify nudi's http://www.nudipixel.net/
