Yes, I rescued some guppy fry several months ago. They were newborns in a tank of adults at a pet shop and I had room in my nursery at the time, so I had them grab all the little ones for me. He's the only survivor of the rescues, I THINK....I don't honestly know, I do know many did die, and I had a guppy give birth two days later, so it's hard to tell. lol All the adults in the tank I rescued them from were female neon yellows. Anywho, he's the only one in my tank like this, the rest look pure guppy. So is he a full Endler's, or possibly a mix of that and guppy?
