Constantella ray are white rays from brazil just like xingu sp humerosa scobinas ect.. Thus the rarity in the hobby.
I'm think tiger ray is the rarest long term.i never seen breeders besides dws group. Nobody has any long term. Every body can get tigers on lists but does anybody actually have any longer than a few years
yup, Constellata. I can never see enough pictures of those rays which sucks because I have only seen like 1 or 2 pictures of them. Very cool ray and I would imagine very rare in the hobby considering I don't know anyone on here who has one.
