What is this?

[Kolby’s Reef]

what are these little brown like clear worms? and are they good or bad? Sorry can’t really get good pictures they are tiny.

Could you get images under white light (ex. with a flashlight)? Also, does the "front" of the worm have tentacles coming out?

As stated, better pic needed.
*random thought -- look up spaghetti worm and see if it looks like that

+1
Also try “medusa worm” (the small ones).

Okay i will get better pic tomorrow are either of these bad?

Both are detritivores and will act as clean-up crew. However, medusa worms become very toxic when stressed (ex. if they get sucked into powerheads).

It looks like there are little tentacles coming out. I’m about to post more pics but couldn’t get any good ones they’re really small

Okay what would this come from? The only live thing i have put in there is sand. My rock was dry rock

Definitely a medusa worm, with the stubbier tentacles. These have not caused any issues in my macroalgae tank yet, however I still use carbon if I think I have stressed one out too much (ex. if I accidentally dislodge one and loose track of it in the water column). I also forgot to add that these are actually a type of sea cucumber:

They may have hitchhiked on frags if you have any. Mine came on macroalgae.

They expel toxins when stressed making them bad news and need to be removed although some favor them for clean up of detritus and waste. They also eat through tissue of crab, snails and some shrimp. They share habits of sea cucumbers and can grow large
Running carbon and a skimmer reduces ay effects of toxins

I run a skimmer no carbon

No frags just live sand and i did get some chaeto maybe came from that?

What do you mean by dislodge it and loose track in the water column? Also how do I run carbon and should I?

I have tried to suck up a few with a turkey baster, but sometimes they fall out of the baster and float away before I can suck them back up.

Also how do I run carbon and should I?

I personally used mine in a HOB filter since I have no reactors, though @vetteguy53081 would probably know better.
