Thats's normal coloration, most albino oscars sold are actually lutino. There is a difference between the two, Albinism is the result of a genetic dysfunction/mutation that prevents the production of melanin pigment and Leucism is the result of a genetic dysfunction/mutation that results in a reduction of all skin pigment.
