Every spring, I put about a dozen feeder guppies into my pond for mosquito control. Around labor day, I net the population out and bring them indoors. This year, I found about two dozen strange fish. They look like stretched out guppies. The color is a powder blue covering both males and females. There are no markings on them at all. The males have a very long gonopodium. The weirdest thing is that their eyes glow like those on lampeye killies. I thought maybe H. Formosa, but the body is totally different. Can anyone identify these fish?
