Neon green worm

[scotty333]

Guys,
This is the second neon green worm I’ve caught in an acro
It’s 1 cm and fluorescent green but what is it?

Maybe @ISpeakForTheSeas can help with this one.

It’s out anyway

Unfortunately, I'd need to see this one extended in the water under white light for an ID - given the color, my first thoughts would be either a green ribbon worm (Nemertean) or a spoon worm (Echiuran) of some kind, but I can't say for sure.

Either way, just for future reference, I would not recommend picking up unknown marine worms with bare skin - a lot of marine worms secrete toxins through their skin, so I'd really suggest handling unknown worms with care (and a good pair of waterproof gloves).

Do you have any anemones in the tank?

 

[scotty333]

Yes 3

Could do with an id here I’ve caught 2 more today

Any in-tank pics?

I believe @Rjukan was asking about anemones because it could potentially be anemone tentacles that have fallen off (it has been known to happen) - I'll add asking if it looks like it could have come from a coral in your tank too.

No there definitely worms and not polyps

Looks like a worm known as a nemertine which eats microbes and snail eggs

Then clear, pics of them in saltwater would be helpful.

For comparison with the nem tentacle thing, though, see the OP's posts in the thread below:

What on earth? Does this need to come out?

this strange looking thing is underneath my condy anemone. It looked like my an enemy was trying to figure out if it could eat it… It also appears to be moving on its own… If it dropped a tentacle, does it shrink to 100th of its size? And keep moving? I’ve never seen anything like this before…...

Ok, they look like a piece of a rainbow bta, I see them around my tank from time to time and that's exactly what it looks like.
As @ISpeakForTheSeas mentioned, some more pics in the tank under white light would be helpful, also a description of how it moves would be good too. When you see another one, that is.

Thanks
My news are a rose not rainbows and the green of this “ unknown” ( although I’m leaning towards nemertine, thanks vetteguy) is truly flouro and I don’t have anything that matches it , torches, hammers nems anything plus it’s black on the underside
If I see another I’ll film it
Cheers

Kind of looks like it could be this guy, just not fully grown yet.

To clarify here, Nemertine (used to refer to worms from the phylum Nemertini or Nemertina) refers to Nemertean worms (A.K.A. Ribbon Worms); Nemertini and Nemertina are unaccepted taxonomic names for the phylum Nemertea.

These were hammer polyps after all , caught my torch sweepers tickling it ( a bit more than a tickle I guess)
