I am pretty new to this. my tank in cycled ammonia, Nitrite, 0. and Nitrate 1-5. I had tiny black worms in my tank, they looked as if they were just sitting on the sand maybe dead. They were a bit thick and only about a 1/4 long. I am not sure what they were I just vacuumed them all out so I dont have a picture. Any idea what they are?

 
Really the description don't say much to can ID them, move a bit the sand surface and check can you see another one, take photo of it, and/or take it out and placed in some water take photo.
 
Sorry not without a pic...
some appeared over night

do you ever saw them to move? because it look on the photos a bit like a fish poo. Can be bristle worm, or parts from feather duster, spaghetti . Try new photo of it, with some zoom or with macro for better photo please.

Sorry, can't say what it look like to confirm, if you see bristles on it, check Bristle Worm in google photos. Try to match
 
Possibly baby bristleworm but pics are too red. Need pics with white lights

no bristles or anything. They just look like little worms. Some are really small and some are longer. but not really anything on them
 
I was going to say small bristles too if you are seeing them all over your rock.. possible a bunch ate something up and then died off when whatever the food source was disappeared.
 
how do I get rid of them? Should I just keep vacuuming them out?
They are a good thing usually, some people hate them, and some people would buy them if that is what they are. I would just leave them be if they are indeed bristles

they all seem to like their dead tho. i think they ran out of food after my cycle. I don't want them to decay in my tank. There in my rock too, so idk if i should take my rocks out since them in saltwater after a watch change.

Remove the dead ones if there are that many. You could use a turkey baster and blow the rocks out/off before pulling the dead ones out. I would assume you are already testing your water for ammonia etc . . if you were cycling recently so continue to keep an eye on things and/or do water change(s) if needed
 
Vacuuming is one method.
Arrow crab is a sure bet

Still hard to tell with the pics but I wouldn't be too concerned.
 
okay thank you! As easy as that would be they scare me a bit since they look like spider lol i saw coral banded shrimp also take care of them so I might get one of those
be careful, not all of the SP in that genus are completely reef safe. But I think like @vetteguy53081 say, Arrow crab is better bet against (read about the particular coral banded shrimp if you find any to buy)
