Tiny white critters

So I let my tank run too long without fish or shrimp and let all sorts of tiny fauna get out of hand. My tank is overrun with tiny round white moving dots. And seed shrimp. Now that I finally have fish and shrimp, the fish (threadfin rainbowfish and pygmy cories) won't touch them. The threadfins will take the tiny white creatures into their mouth but spit them out instantly and aren't making a dent in the population. They're all over my glass and driftwood. What are the tiny white moving dots and what eats them? And what eats seed shrimp? They're quite large and constantly competing with my cherry shrimp for food.

I also have Threadfins in my tank. I found for the first cpl of weeks they are Very picky and then start eating everything but the food has to be tiny tiny. Give them a little longer and they may start eating the things you have in your tank

If they are quick moving, I'd guess they are probably cyclops. I'm astounded that your fish don't eat them. Ditto on the seed shrimp.

Cyclops aren't actually round, but they are white, and they're so small that you can't really tell what they are without really looking close.

I think the rainbows and pygmy cories MIGHT be eating some of the smaller seed shrimp since I now only see fully grown ones in my tank. But nothing is touching the tiny white dots ): They're covering my tank walls and look like white grains of sand or air bubbles. They are whitish-clear and slightly oval shaped and about half the size of a nerite egg. I can't really tell anything more without a microscope.

Are these your guys?



They are called limpets.

"Since freshwater limpets, Acroloxus lacustris, are so small and also move really slowly, it might be hard to identify them as snails. They are small and can't do much damage to plants, but since they are small, it's impossible to find and remove eggs and the baby snails. Harmless.

Something that looks a bit similar are Nerite eggs. They are singular, white, hard, round or oval shaped and about 1 - 2 mm in diameter."

I would kinda rather they were... these guys move around quite a bit and don't move slowly :/
Someone on another thread mentioned they might be white water mites and that fish don't eat them.
