Nudibranch eye candy

Here's some photos of Hermissenda crassicornis and Navanex sp., coldwater California nudibranchs. Navanex (the dark blue/green one) is about 6" long and feeds on Hermissenda. Very cool to watch it suck one in. The upper right side of Navanex is the head. Hermissenda feeds on coral polyps, I believe.

Hey, you didn't have to pick them up

 

[reefNewbie]

are you able to keep them alive in your tank for long periods?

reefnewbie, time to change your name. I just realized how close I'm getting to squat... the new me will be Marsupial when I hit 999 posts a la 7E, OP, RG...

We can keep Navanax inermis alive for a pretty long time by feeding it Hermissenda that we collect. Hermissenda usually ends up withering away fairly quickly. It feeds voraciously on very small cnidarian polyps, and although we collect lots of polyp covered rocks, we can't keep up with their appetite. It's one of the most abundant Pacific Coast nudibranchs (It ranges from Alaska to Baja), and we only collect a few. It's sad that we can't keep them alive, but hopefully the ends (educating 700 undergraduates by showing them a live nudibranch) justify the means (taking it out of the ocean to die).

Hello everyone! I'm new to this site.

I frequent another reef blog site, and one of the guys has an infestation of the monti-eating nudis. After googling around, I found that N. inermis is known to be a voracious eater of them.

In fact, I found this amazing video: http://www.life.uiuc.edu/slugcity/movies.html

I was just wondering if N. inermis is available anywhere in the hobby..? I realize they're a cold-water species; Can they survive in the warmer tanks?

I was just wondering what you know about it.

Thanks!
