Hello,
I have these in my tank. I just removed three of them by hand. Unfortunately I ended up ungluing one of my frags. But I got the little suckers.
These send out web like tentacles and bother the corals and fish.

Any ideas what they are, and how I can get rid of the rest? I am unable to see the bodies of the others, but I do see the tentacles.

Many thanks!

To me that looks like a bristle worm, but you said tentacles? You don't have pics of them in the tank? Yuu could be seeing two different critters.

Hi @El_Guapo13.
Unfortunately no pictures of the worms in the tank. I can try to get pictures of the tentacles, but they are a bit tricky to even see. I'll see what I can get tonight.

Does it look like this? If so those are spaghetti worms. But the one in your original picture is definitely a bristle worm. Bristle worms are good CUC. Spaghetti worms are good diversity, but they don't make as much as a contribution to clean up as bristle worms. Both can reproduce fast, particularly bristle worms.

Agree.

Thanks gang!
Vermetid snail was one of my thoughts as well. I did get a couple of pics, not the best as it's rather difficult to get a picture with the tentacle flowing that shows in a pic.

Ideas on how to get rid of the vermetid snails? Any natural predators?

Small bristleworm. Although great sand/filter feeders, they’re not welcome in any of my tanks. If removing- DO NOT touch them with bare fingers

Thanks @vetteguy53081!
I try not to touch unknown stuff with bare hands if I can help it. The ones I took out I used long tweezers. I'm sure I have more worms, but nothing that is obvious at this time.
