Bristle Worms

Snail ID?

LFS said it was an Aussie Rock Snail. Looks encrusted or like someone glued a frag on it. Moves slow, clumsy as hell, and has tube worms growing on it. Possibly more, but nothing soft. The large tube at the underside had a large bristle worm in it that eventually moved to the rockwork. Keeping them under control with a wrass for now, but can't find any info on this snail. Not sure if the bristle worm was symbiotic or just a hitchhiker.

This bristle worm was in my filter. I pulled it out, and it jumped onto my desk, literal nightmare fuel.

MONSTER bristleworm out tonight

I found this shrimp thing again and caught it, looks like a small boxer shrimp but idk, also found a bristle worm i dont know the species of, help would be appreciated, currently its in a seperate mini tank so i can observe it as polychaetes (if you couldnt tell) are my favorite animal

Bristleworm?

Does anyone know if arrow crabs will eat bristle worms much larger than themselves?

Bristleworm or fireworm? It was in my Aiptasia tank. Tried to feed it to my Aiptasia but the Aiptasia didn't like it.

I finally caught my first 2 Bristle worms with my DIY trap!!! Frozen Mysis worked excellently!

Hey everyone! Just looking for a second opinion on this, is this a fire worm? I think it is but I really have a hard time differentiating bristle worms and fire worms

Does anyone have spaghetti worms? How do you fight them? They are so ugly with the tentacles waxing in the flow. I’m 100 percent sure they’re spaghetti worms

What. Are. These.

I’m kinda freaked out by the fact that there are random worms living in my sand.. please help me id these. Are they bad for my tank? Will they hurt me or any tank mates? There’s so many ‼️😬

Anybody else have one of these guys?
