Picked up my hybrid Ansorgii from a small locally owned pet store. I asked about what Polypterus he could order and called up his distributer right than and ran down the list. He said he had a few 6"+ "Geniuas", which I knew it wasn't an upper jaw species and I don't know much about the lowers which I knew this had to be one, I figured maybe a Lap or something less common than the Endli and just took a chance.
