Didn't quite know what forum to put this in so I figured the invert section would do. I was asked by a manager at one of the local stores to figure out what this is. They are swimming in all the tanks in the store. I don't know if the bugs are actually on the fish or plants. They are about 3-5 mm long and wide and about 1 mm tall (very compressed). They can swim very quickly forwards and backwards. Now you know all that I know. Anyone?
