Ostracods. They feed on algae and detritus, so completely harmless and actually an indicator of good water quality.

I wonder where they came from. I don't have anything new in the tank. the snails are 3 months old and the betta passed away last month from a swimming bladder problem.
I think that they are capable of producing resting eggs, so could remain dormant in the substrate for (very) long periods until conditions improve. If you have recently switched to RO or rainwater, this could have triggered them to hatch, but more probable is that they have hidden away in a corner until it was safe to come out.
