I have a planted 20g high which has been going for 9 months now. Today when I was feeding my fish I thought i noticed some little bubbles popping on the waters surface. Well as more and more caught my eye I realized that it was really super ting bugs hopping around on the waters surface. It appears as if there may be a dozen or two of these little guys. I would say they are smaller than a pin head. If they are a problem I'd like to get rid of them, otherwise I don't really care. Can anybody tell from this pic what it is I've got?
