I am finding that my bar tank can only support rays up to about 12-14" in diameter. I was originally thinking to breed and then sell the mating pair and keeping the pups. The tank has no top lip and once the rays pass 12" they like to splash water over the rim and watch me clean it up 
I am wondering about purchasing a couple of black rays and growing them out for 1-2 years and then selling to a breeder. I know we do not know the future prices for black rays and in hind sight I could have bought a few and be selling them now for a mint. Money is not a big of a deal as the Wife Acceptance Factor. I cannot have any more large tanks (I really don't need or want any more.)
Any ideas or complications that you guys see? Also at what size do the Leo's turn jet black. All the pups are grey. If they don't turn black until 9-10" I may have only a few months with a black ray.
