I’m not sure if there’s a technical term for this type of guppy, but I’m calling them spike tails for now. These are really colorful, hardy and fast. I don’t think I’ve ever had this type of guppy get any type of disease. (None of that dreaded clamping disease here!) I believe they are a cross between a lower sword guppy and a ginga rubra guppy. They are still on the young side and small, and kind of look like a pimped up wild guppy. So what I got is a shorter and wider “sword,” and some of the ginga body pattern was masked out. It’s an interesting fish, though I’m not sure where I’m going with any of this.
