well, if no one else comes up with a better one, then guppy you can bring us the next contender. honestly, i don't have a positive id on this fish. I've corresponded with a few taxonomist and they have concluded that this is a new specie. I've had over 10 specimens all looked the same, so I don't think its a leucistic nandus nandus. Anyone else? If not, go ahead and move on!
