These are at the base of a coral I dipped last week due to spionid worms. These look different but could the be spionid? The have some sort of tube structure, then a bunch of white flowing tentacles. The spionid worms just had two antennas which is why I think this is different. What should I do about them?

I dont know what they are, but i have them too. The reason I have them is my tank died last year and instead of quitting I decided to let it run and mature. Now I have a lot of them. My Diamond goby picks them up and stacks them into a pile and I scoop them up and throw them out.

I do not think they're harmful, but they can be annoying. I have not had any problems with them. They like to take shelter under frag plugs and rocks, but sometimes they will poke up right out of open sand.

I’m just worried it’s the same frag that had spionid worms and I don’t want them back. Not sure how they reproduce, but this looks different than spionid.

No, those worms kind of stick themselves together a tube out of sand and then stick up out of the sand and filter-feed. I have had no issues with any corals. Sometimes you'll find them around a frag plug if you had it stuck in the sand, but they are harmless and will not bore into coral. They live in the sand and stay there.
