I will let you know more on this thread when mine hit maturity. I have 1 male and 2 females. Mine are all captive breed and the parents were at my lfs and breed like rabbits. I am hoping to have the same luck. The female was always pregnant within months of having pups. Now my rays, the females are only 6 months old and the male is 1 month old so I have some time before they will be ready. But I will post updates. I am custom building a tank that will be 8' x 4' by probably 20" tall. I also will have a drip system and enough filtration for around a 1000 gallon tank. Water quality is a MUST. I will also be keeping their grow out tank (a 75 gallon with 300 gallon worth of filtration) up and running for a "time out" tank for the male or females if necessary or hopefully more so the pups!!
My main concern for water conditions are ammonia, nitrites, and nitrates. I am not as concerned with the rest of the water parameters because I have the exact same city water as my lfs. That is what the rays were in until they let me take them home. So they were already used to the ph level and the hardness and they did not us RO water so I figured I was safe there. I currently have 0 ammonia, 0 nitrites, and 20ppm nitrates. I do 20 percent water changes every other day as I do not have a drip system in this tank. I also use 2 aquaclear 100's and 2 50 gallon sponge filters on this tank. Like I said water quality is very important. Ray's actually urinate unlike fish and it is pretty much all ammonia. Hence all the filtration and filters.
Hopefully I have given some good insight. I am by now means a pro since this is my first attempt.
