If you have a pair of any type of shrimp in your tank, that is likely exactly what you have, a big hatch of baby shrimp.

If you are lucky enough to catch it, it happens just after lights out, once or twice a month depending on how many shrimp you have in the tank.

Very cool event. I have only seen it once in my tank, but the corals and night feeders surely will be feasting.
