Are these some sort of parasites?

Found these in the corner of my breeder box lid this morning anyone know what they are and if they’re harmful to fish? Thanks in advance.

@modified lung anything you recognize?

I thought it was an easy ID at first, but zooming in and trying to see the detail it was more of a mite shape than what I thought it was.

If you can at all @Davidg try to get a macro shot or something with slightly more detail.  Welcome to the forums! Glad to have you here.

Could be collemboles. Aquatic springtails.  They come in on plants or leaf litter. http://www.wetwebmedia.com/AqInsect IDF.htm

I don't have personal experience with them, but just skimming a few articles - it seemed to indicate they are harmless, fish food for top-feeding fish.

@Biotope Biologist?
