i need some advice. i have these little green bugs in my aquarium. they're about the size of a gnat and they live on the surface. they sort of skip around on the surface and every time i open the lid a few fly out. i also find them on the underside of my lid. i believe they start off as these really tiny worm-like things (larvae maybe?) from there they turn into these little bug-like things that swim at the top of the tank, just below the surface, usually right next to the glass. from there they turn into the little green bugs that scoot along on the surface and bith my cat and pleco died mysteriously....?
