Substrate bugs

I see tiny weeny bugs / insects zooming about the two aldabras in their closed chamber at night.

I’ve read up here and decided it’s nothing I worry about.

Tonight I saw they were in quite large number (nearly transparent and tiny), and they grouped a bit on one of the babies heads.

She’s gone to sleep and could care less it seems. Should I do anything?

See photos - bad quality - pulled from video. I could upload video somewhere? You could then see them zooming about all over them.

I think they are harmless...

To note: substrate is 80% coconut coir, there's hay in the photos that you see- that was a mistake- in the next substrate change it will end up 100% coconunt coir. No hay.

I have tiny bugs in my red foots cage. She is around 9 months old. They don’t do anything. They are like mites. I read somewhere that they actually help decompose the poop. Just make sure they tortoise eats good, and poop and pees regularly. They shouldn’t harm anything.
