Anybody know what this is?

I spotted this in my buddy's tank today. Wondering what it is.

 

[uh.oh...]

So I take it it moves correct? Like a worm?

 

[JJ-MIK]

Yeah it was moving up the rock.. Looked like it has about 30 legs plus. And 4 feelers...... ??

Gotta be a nudibranch.
Not sure of the genus tho, soooo many.

Protaeolidiella perhaps.

What kind of corals does your buddy have? With arms like that it may eat torch corals. Just a guess tho.

I think it's a nudibranch. I think I stumbled apron a pic of it when I was searching from a nudie I found in my tank. Not 100% sure though

 

[JJ-MIK]

The closest I came on google was a walking cactus.. Same shape. But dif design...

 

[Ingy]

Considering that the Walking Cactus is long extinct, my money is still on some form of Nudi

 

[JJ-MIK]

I've been on google for 2 hours now and can't find it. Another close one is a dear slug. But those are hairy like. This one is solid. Like a stick...

 

[Ingy]

Yeah, I tried to google it as well. Came across a Nudi search page that had 21 pages of Genus' of Nudis. Some Genus had 9 sub-whatevers that all looked completely different. I gave up. I looked for corals that it looked like as they often look like what they eat (camo) and Gorgonians seemed the most likely. But that didn't help finding an exact match but Facelina annulicornis semed close in some photos (but not in others).
Has he had any corals mysteriously dying?

Marine Flatworms of the World!


I would email these guys....

 

[JJ-MIK]

He's had a few die. But that's because the copper banded is our of aptasias. Lol

 

[JJ-MIK]

Thanks X!!i will give it a shot

 

[mr_X]

Also email Chuck. He always got back to me when I had a nut I couldn't crack....

Closest I could find was the Flabellina. But most were bright colors. I'm tagging along for the answer! Looks like a walking stick. Lol.

 

[JJ-MIK]

That's what I thought! Haha I'm kind of hoping its a never before seen species!! I want to name it!! Lol

 

[JJ-MIK]

There are 9 of these in the tank now.. And there in the polyps. I think destroying them!

 

[JJ-MIK]

I finally found it on the net. But can't find much info on it.. Phyllodesmium briareum nudibranch .... Can anyone tell me if these are bad for a reef tank?

 

[Riverhawk]

Theres bookoos on the net..i googled it..eats sea fans but youll need to goohle it..

 

[JJ-MIK]

Seafans? I only thing I found was they hide in and eat zoas...

 

[mr_X]

Pretty close I.D. I would say it is correct. My link says it eats soft corals.
