Worms in newly cycled tank

434 2
The tank has been running for about 3 weeks. Plants and a couple of fish have been added. Today I noticed a bunch of small worm/ larva looking thinks wriggling around. Can anyone identify and are they harmful?

thank you

They don't look like typical aquarium worms to me, more like the larval stage of an insect. Can you remove them to another container in a bit of water and take another pic or two?

It might be dragonfly or damselfly nymphs or it could be something that came with your plants.
