Nudibranch ID       11/3/18
Are you able to identify this Nudibranch that was found in a tank that has lps and Zoanthids and gorgonians
Thanks
<Mmm; black rhinophores, gills, spots, yellow margin, white body, flattish; small for now... this at least resembles the Heterobranch Felimare kempfi (Ev. Marcus, 1971); was/is there rock in this system from the tropical West Atlantic?
Unless I saw it eating something valuable, I'd leave/enjoy it. Bob Fenner>

Hi Robert
<Hey Otilia>
Thanks for the reply what would be the expected diet of this Nudibranchs so I can try to feed it adequately.
<Mmm; a tough one. Likely whatever it will accept is in your system, shipped with it. Many Nudibranchs eat types of Hydrozoans... but need to know what you have here exactly. My guess was just that; a guess>
It’s not in my main reef tank due to potential risk and trying to hunt it in a 6ft heavily coral stocked aquarium.
I would like to keep it and am happy to even give it frags
<Then I'd go ahead and place in your main display. Most nudibranchs don't consume/nibble on species aquarists keep.
Not at all likely to be problematical. Bob Fenner>

Sorry for a second email I just looked up that species. It says it is mainly from the northern hemisphere. I live in Australia.
<Ahh; not it then. The one mentioned is from off of the southern Caribbean on south>
We are not allowed to import live inverts including coral.
<Yes; am aware. Do take the long look on WWM re my pix of Nudis...
something similar look up the genus on the Net; Google, look at images. Bob Fenner>

Can you ID this?
<Mmm; appears to be a Tritoniopsis sp, may be T. elegans... soft coral eaters. Bob Fenner>

Hi,
<Tracy>
Found a dark Nudibranch with white tips on frills and antenna, came as a hitchhiker on red macro algae, less than 1/2 inch long when stretched out.
Would like to know what kind this might be and what it eats.
<My guess is on a Flabellina sp.; perhaps F. exoptata: http://www.wetwebmedia.com/nudibran9.htm
Most Flabellinids eat Hydroids>
So far a hermit crab tried to pinch it and the slug retracted, the hermit looks like it got stung or slimed and backed off cleaning it's pincer arm. Slug moved up a rock and then floated off - drifted in the water current a bit (fortunately not getting sucked into the filter) and landed in back of the tank out of view. Hermit is doing ok now. Attached photo. Any insight to this critter is appreciated, thank you.
