Funny how the sword is on top of the tail, not at the bottom. I've said it before but hey: nice fish. Really curious about how it turns out if it matures more.Semantic Drift said:Platys and swordtails (X. maculatus and X. hellerii), if kept together, can fairly easily interbreed. So it's probably a hybrid between a platy and a swordtail, would be my guess. They're different species, but they can still reproduce and make fertile offspring (like dogs and wolves, C. domesticus and C. rufus).
