Ok, these things are too small to get a good photo of, but I'll try to describe as best as I can. They are small critters, about 1/32" approx in size and are watermellon/oval shaped. Some are bright blue and some are bright green in color. They motor all around on the surface of the substrate, and go all the way to the surface of the water. I can't see any legs either. I hope my verbal description is good enough for an ID. If I could see a really good close up photo, I could say if that's it or not. They are all over in my 10 gallon, heavily planted, and I only have cherry shimp in there and snails - no fish toeat these guys. I don't want to introduce fish as they might eat my cherry shrimp fry. Any ideas? Should I get rid of them and how? Thanks a bunch!
