I just found a bunch of eggs in my tank. What do i do?

Not much you can do! Is the mother still in the tank if so she'll look after them. If not you'll need to occasionally send a gentle flow of water over and through the eggs, a turkey baster works well. Once they hatch...if they do.....you'll need to have a LOT of amphipods etc ready for dinner. And expect many of the squirts to die off or be eaten by sibs.
