First off, it's an opistobranch, not a nudibranch. Nudis lack shells completely. Second, since you found it on the Sea Slug Forum at http://www.seaslugforum.net/factsheet.cfm?base=bullline you should have read the accompanying info which said the only reported prey items are polychaetes. Third, you shouldn't post other people's pictures without permission or credit.

Shelly Beach, Manly, Sydney, New South Wales. October 1986. (Shell length 15mm). PHOTO: Bill Rudman.'
http://www.seaslugforum.net/factsheet.cfm?base=bullline

There now that is done, the fact sheet does not specify this question!

?


Thanks

I don't want to mess up your thread but I have the same question about a Nudibranch that is 100% black with tiny white tips on its antenni. I have no idea what it is....

I had a couple nudibraches that lived off the macro I had in my fuge that were golf ball size. It was a 10g fuge, 15g display, and a skimmer - it didn't hurt anything when they died a year later or when they very rarely inked.... but I'm sure it's different for different species.

If you had a slug that ate algae it wasn't a nudibranch. All of them are entirely carnivorous. If it produced ink it was a sea hare.

Most nudibranchs won't harm the tank when they die. There are a few families that can nuke a tank though. That's a fairly irrelevant question though since as Leslie pointed out, the animal in the picture isn't a nudibranch. I've yet to ever see the animal in the picture make its way into the hobby, so it's hard to give a definite answer, but it's very unlikely to be significantly toxic. It doesn't eat a very toxic food and most of its relatives aren't particularly dangerous.

Probably Dendrodoris nigra. They're predators of sponges and seem to be one of the only dorid nudibranchs that occasionally does well in reef tanks.

Oh, my mistake. I see that Sea Hares and Nudibranches are Sea Slugs but sea hares aren't nudibranches.

Thanks for adding the information. I know a lot of people think anything on the web is public domain but it's not. Reposting & hotlinking are practices that many photographers hate.

But on the other hand allot of people just want to share their work. I'd rather have a culture of sharing than ownership (non-commercial at least). If the photographer is anti-sharing and have the ability they can setup their server to give out a different image when the referer isn't from their site.
