Eel/Fish hitchhiker?

[Lewis N Sophie]

A friend of mine has a fluval edge nano tank which pretty much has a fish and some liverock with a couple of small corals. Nothing new has been added since I gave him some xenia months ago.

He now has this:
YouTube - ‪What the hell is this??‬‏

Not something I've ever seen before.
Any thoughts?

Woa! No idea LOL! Looks like a Huge, High Speed, super Flat Worm (which it's not.. I don't think) but man it's cool looking. What does it eat?

 

[JoeG]

Woa! indeed. No clue here either... looks like some mutant over sized tadpole. Ill be checking back to see if this can be ID'd

 

[Lewis N Sophie]

Really weird huh? No idea what it eats although I was going to give him some cyclops or artemia and some nori to see which it has a go at first.
Pretty fast though and disappears for days before coming back. Seems diurnal but who really knows. I've only seen the video so far, if I see it in the flesh I'll try to catalogue it better.

 

[BigAl07]

Can you go over there soon? Like NOW? I Wanna know what it is.. and does it taste like chicken


It does look like a Tadpole on crack or something LOL

It almost looks like a marine flatworm that we saw a movie about in science class. That thing's fast though. Awesome!

 

[Boomer]

It swims like and looks like a Epitoke, which is a reproductive phase in polychaete marine worms, where the worm undergoes a transformation ( like metamorphism in insects) to an Epitoke.

Thanks for the ID Boomer! Here's a thread with a video of an epitoke in post #1 - the swimming action looks a lot like that in your video.

Great pic and link mack

 

[Reefmack]

Thanks Boomer. When I saw the video it reminded me of the other video I had seen.

 

[Funlad3]

Mystery solved I think!

 

[BigAl07]

Man that's some amazingly fast movements off of those cilia. Impressive!!

Way to go on the ID and the additional link

 

[QuentinB]

Holy crap... I kinda want an army of them little guys! I'll wreak havoc on public pools and beaches EVERYWHERE!!!

 

[Lewis N Sophie]

That's awesome guys, thanks for the quick ID. I have to be honest, it had me completely stumped, I was reading biology journals on line and all-sorts to try and find it. Should've known to just ask Mack!

Thanks again!

Actually Boomer is the best at these things!
