need help with an ID

hi all

i got a yellow/green nudi said to eat algae but after 5 days of it running around looking for food and not finding anything i rang lfs they than said they only sell lettuce slug and blue dori

i dont think this is a lettuce slug can you help with ID and food but i think food will now be a long shot as the research i have done in the last 2-3 days say that all nudis are a real problem to get food for

 

sorry man, ive never seen that one before

 

Looks like a lettuce nudibranch to me.. Well aside from the cool bluish color and gold speckling, but body shape appears that way.

Inwall sure knows his inverts he'll tell you if I am right or if its something else.

If it is a lettuce sea slug they tend to eat diatoms, and also filamentious algae, well as long as its not to long.

 

hi guys found a nudi link elsewere to the sea slug forum and found this

The Sea Slug Forum - Ceratosoma sinuatum

so the little chap has gone back to the lfs with a copy of the page
i'm please to say that all were taken off sale and removed form the shop tanks

and placed i q-tanks but its ashame as i think thay will all die

thanks for you help all

 

Yes, that's it of course. It's a spectacular nudibranch, and a shame they are essentially impossible to keep in aquaria. Maybe a hundred years from now their food sponges will all be known and aquacultured (but the world probably needs a few dozen more sponge taxonomists for that to happen, I suppose).

Cheers,

ya thats definatley a lettuce sea slug most people think that they eat GHA but they only eat bryopsis which is similar in apperance a slug that gets rid of GHA is a Sea Hare

 

Not. It's a true nudibranch, and feeds only on sponges, probably only on one or a couple of species of dysideid sponges. "Lettuce Sea Slugs" don't have an external gill (nor blue spots).

Cheers,



Don

 

idk..... the only thign i would agree with you on is itsa nudibranch other than that im stickin by my original story go to liveaquaria and look under there nudibranch section and find the lettuce nudibranch and read what it eats

 

What? Lettuce sea slugs don't even eat bryopsis, at least with any regularity.

 

I was under the impression that there is no animal known that eats bryopsis.
