Any ideas?

Found this weird worm on my glass, any ideas?

Here's a youtube video incase the other one didn't work.

Any chance of closer pics of the worm? I can't see it well enough to offer a proper ID.

Either way, based on the small size and slow movement, I'd assume (possibly incorrectly) that it's harmless; but I obviously can't say for sure at this point.

Here you go

Don't know if you could see those pics because I can't here they

are again.

@ISpeakForTheSeas here's more

I still can't quite see it clearly enough, but I can tell it's quite an interesting little critter and not a typical worm. I don't suppose you have a microscope you could get pics with?

Ah, these ones are clear enough I may be able to work with them on my pc tomorrow.

Sadly not, the reef has drained all my money for one. Once silver prices go up I'll get one lol

What should I do with him in the meantime?

I'd keep it contained; it will probably be fine in that container overnight, but if you're concerned, I'd figure out a way to float the container in the tank/sump (to temperature regulate it) and add a tiny piece of fish food and a tiny piece of algae to see if it eats either.

Got it, thanks

Got it, thanks

So, taking a closer look today, I'm thinking a Runcina sp. headshield slug - if so, members of the genus reportedly feed on diatoms, so it would be a keeper.

If you do a Google Images search for "Runcina species" you should get a number of good images you can compare with; the (at least mostly) solid white and black stripes forming the collar there can be found a few different species in the genus, but I'm not familiar enough with the genus yet to know which species your specimen might be.

Wanted to come back and say thanks, these guys have multipled into a small fleet that comes out at night. They clean the sand, the glass, and the back panel. I've also seen them in the branches of gha patches, are they known to eat that?

Doing a little more reading on these and their close relatives, I wouldn't be surprised if they did, but I can't confirm it. All I've been able to find for sure is that they reportedly eat diatoms, algae, and "dead marine phanerogams" (dead seagrass).
