Does anyone know what these are?

Hi, we have a tropical aquarium, we only have borneo suckers, neon tetras and a couple of Danios at the moment.

We have a patch of algae growing on the glass and have noticed these small white creatures this morning. They don't seem to be moving around the tank, they seem to be on the glass, specifically where the algae is and are moving around on the patch of algae.

I've done a water test this morning and it's all fine.

Any idea what these are?

Ostrocod seed shrimp . They’re harmless and indicative of a healthy aquarium .

Ah okay that's a relief thank you. My son was hoping they were borneo babies but I was worried they might be something harmful!
