Hi, I've got this little bugs living on the water surface of my
freshwater aquarium, and I have no idea what they are. I recently got
a whole bunch of plants from a friend who was thinning out his tanks,
and I am thinking they must have come in with them. They are extremely
tiny, light brown dots, and they jump around on the water surface like
fleas when disturbed. There are a lot of them. Any ideas? Can anyone
help me?
