Some kinda worm?

[GillMeister]

I've seen plenty of various worms in my tanks over the years, but I see something I can't ID. I have seen several of these small white worms, about 5mm long. I don't see legs or bristles on these little guys and they can move fast. What is this?

I can't the video either. FWIW, I've had good luck uploading to Vimeo

It's hard to tell but it looks like some kind of marine nemotode. There are some that are fish parasites but most are not and I think I read that the white ones we find in our tanks are generally harmless. I could be very wrong, I can't make out any fine details on the critter in your video.

Planaria- net out or siphon out and discard. Look around tank for a few days- daily for presence of any eggs which are tiny. Should you find any- scrape off and discard

I think planaria are flat. Aren't they? These are like little slivers.

To be more specific - Turbellaria which is a type of planaria. If smaller may be a nematode

So, not a good guy? Will fenbendazole nuke them?

Should but net or siphon up without chemical
Most wrasses will eat them
