Little white bugs in my tank(a lot of them) !!!!

Heh, I don't know of any fish that would pick at those seed shrimp and yet not eat baby shrimp. If they truly bug you then just clean your tank. Vacuum the substrate (if it's sandy then stir it with a stick and hold the siphon/pipette just over the substrate) do a substantial water change (might want to age the water, shrimp are sensitive) feed things like nori and veggies for a while which are not polluting, and you will see their numbers dwindle.
