Those little 1 to 2 millimeter round ostracods are everywere. Their eggs
are really tiny and could have come in on any of the plants or on the
shells of the snails. I bet you had those little guys a long time before
you noticed them. Fish never seem to get them all. I am beginning to
suspect that Ostracod eggs are resistant to drying and bleach treatments,
and who knows what else. They probably couldn't survive autoclaving or a
direct nuclear hit, but that is only a hypothesis!
