It's blue, about the size of my thumb, it has fins (I think there called that) from the top of its body and the bottom, and has two weird antenna like things sticking out of its front. I bought it at Meijer a little over a month ago and it's been living in my filtered 10 gallon tank ever since. Anyone have any clue as to what species of fish I have? I am curious because out of the 10 other fish I had in this tank over the past month, this is the only fish to have survived since day 1 when I first purchased my first fishes and the aquarium itself.
