i have these tiny little shrimp things in my tank that have suddenly appeared in the past 2 days and they are constantly at the top of the aquarium as soon as the lights go out. when the lights are on they just drift through the water or hang onto the glass.they are very tiny approx. 2-3 mm in length, and a clearish tan color. i think they are some kind of pod but i dont know. What exactly are they doing and why did they just suddenly appear?
