Something I can't ID.

[AcroNem]

So tonight I'm calling on you guys to help ID something for me. I've been doing this for almost 13 years and cannot for the life of me find what these are. I call them "slugs" in the video description but that's probably incorrect. This is in one of my propagation systems where I'm raising Epicystis crucifer anemones, you can see a couple babies in the video (and two Aptasia, forgive me). If you know what these are, please share I'm very curious. Best to watch with volume down, there's a lot of pump noise. I've only ever seen the pair of them and they're never far apart, so odd. Anyway thanks for any input you give. Looking forward to your ideas.

@Lionfish Lair they look like shelless snails.

They're strange, it's like a shell less snail, or a sea slug/nudibranch, or a Cucumber. The way they move was throwing me too.

+1 on the sea slug. That may be.

I think its a cucumber, but I cant find ANYTHING on it.

Do they have any antennas?

Looks like some kind of worm.. I'm not familiar with any cucumbers that are that quick.

 

[AcroNem]

Don't see any antennae, I'm flip flipping between those few possibilities.

I don't know about it being Cryptoplax, doesn't seem to look like anything I can find in those species.
