Help identifying

[Jahnny]

This just appeared in my reef tank today. Haven't added anything in 3 weeks so not sure what it is. Looks to be a snail of sorts with the shape and style of foot. I looked up all kinds of nudibranch and didn't see anything like this. It obviously moves since it wasn't there this morning and when I got close to it, it seemed to flinch some but has been in the same spot for several hours now. Appears to be almost feathery in appearance. Greatly appreciate any help in identifying what this may be.

Can you try placing a small bit of seafood in the tentacles? First rule out that it's not an Anemone.

I will try that once I find it, seems to have moved outta sight over the night. What should I look for after placing food on it? I have some coral smoothie and marine snow. Or use brine or mysis shrimp?

Mysis shrimp. It needs to be a meaty piece of seafood. It the food is ignored or the food scares it then it could be some type of Nudibranch I've never seen.

 

[Jahnny]

K thanks. Still can't find it. Looked at hundreds of nudibranch pics last night and didn't c anything close.

If I had a clear picture that would help. Based on the little white dots in the tentacles I think it's an Anemone.

 

[Jahnny]

I will get more if I can. It was in the same spot last night for several hours and this am it was gone. Never had an anemone attach to the glass before. I'll add a new pic if I can find it and get a better angle.

 

[Jahnny]

Seemed to move around a little after getting some food on it. There's like 5 hermit crabs all around it now so can't get a better pic now

Not thinking anemone, it moved from the bottom of one side of the tank to the opposite side towards the top. Unless it's a fast moving one, I've seen them only move a few inches at a time and only within a few inches of where they initially are placed. It's in direct line with circulation pump and it's moves body moves like the GSP's n galaxia do in the current.

Finally came our where I can c it better. Looks to have the makeup of a snail with the antennae like it does.

 

[Jahnny]

Sure seems to have a foot like a snail

The picture in post #10 shows what appear to be antennae, which certainly indicates NB. The closest thing I've found is the frosted white nudibranch. It may be an undiscovered species, and you may have the only known creature in captivity... lol!

Nice! Thanks for your input on this.

No idea what it is but it sure is cool.

It's def cool. It moves quite fast when it wants to. And hides for days too. I will keep an eye on it to c if it's harmful to any of my corals or fish but so far seems peaceful n harmless. Thanks for the input
