I have all of a sudden noticed a large amount of white critters on my rock where there’s algae and on my glass when the lights have gone out.

I’ve dossed copepods before however they never looked like this ...

Any ideas many thanks.

please see images below tried to get best images in microscope as possible

While they can be a food source for certain fish, they do feed on microorganisms and organic debris and regarded as filter feeders BUT do know that some species may predators to smaller inverts
