Worm ID

Gudhjem · Oct 4, 2022

Please help me ID this one. I spotted him slithering over my gonipora. Moved like a snake (See vid). Zooming in on the photo, I can see long fine legs. Tank has plenty of bristleworms, but this doesn't look like one. It's longer, thinner, not bushy, and moves differently.

Thanks in advance.

Honestly I would keep it, its just doing it's own thing

The fact it's got to this length without you noticing and unsure if you introduced purposely but I love it.

Others will help, I'm sure of it

It's definitely not your standard bristleworm, but the term technically applies to the whole taxonomic class, Polychaeta. My guess is this is some kind of Syllid worm, possibly the "Blue-tailed Syllid" as it is known in the hobby (I haven't been able to find a scientific name for them yet) - these guys are noted to be commonly found crawling over Gonis. These guys aren't known to be harmful, but they have been known to occasionally irritate corals they crawl over (likely because of their long chaetae).

goniopora receding (found a worm)

We have a goniopora thats slowly receding. Its not brown jelly & I have alveeohpora that was about 3" away & its thriving. We have been moving it with no results. Its receding rapidly & its looks healthy (whats left) & I spot feed. Today we were moving it again & found a worm, I have never seen...
