Re: bought as Oyapok but definately isnt
I've never seen an Oyapock or 'Pallid' tinc with any amount of yellow as an adult. Occasionally my froglets will morph out as a darker cream color, but they lose it quickly, and mature to become primarily white, or bluish white.
As the frog in question is almost certainly NOT what it was sold as, no real determination can be made to it's origin based strictly on its appearance.
Try to get some more info on it if you can from the previous owners, otherwise just enjoy it as a nice-looking mystery frog, not suitable for breeding.
