Who says? That first pic that the OP received looks awesome. I'd buy those in a minute. Not for $16 though.From what little I've read I though guppy/endlers were 'useless' as in you won't be able to sell them
Just because a mutt endler/guppy is no longer pure doesn't mean there is not a market for them. Look at Tiger Endlers. They are very popular and are crosses and sell for more money than the pure endler strain that created it.
