ID please

[jpndave]

Does anyone have an id for this guy and is he good or bad?

 

[pagojoe]

He may not have a name, but you'd probably consider him to be a bad guy anyway. He's a nudi, and probably eats zoa's or some species of soft coral. Similar species even feed on hard corals.

Cheers,



Don

Is that a Bergia?

No, but it looks vaguely similar because it's in the same group of nudibranchs. This one is an undescribed species of Cuthona, which feeds on zoanthids like Don said.

I was probably the one who first said it was an undescribed Cuthona. I got that from a tentative id in the Sea Slug Forum based on a drawing. This SSF thread however has photographs and the animal is called an unknown aeolid nudibranch:
http://www.seaslugforum.net/showall.cfm?base=palyfeed jpndave - those are very good images and I'm sure Bill Rudman, the man behind SSF would appreciate having them. You can submit them at http://www.seaslugforum.net/message.cfm?id=new when it's open again.

If you have zoa colonies time for some close inspection and possibly fresh water dipping. Hope you dont have more of thoe nasty little guys in your tank


Admittedly though, if I could have a species tank of nudis, they are extremely pretty but i don't think i could afford to feed them zoas all the time
