Shouldn't be a problem as the others said. Really nice rays you got especially the black but then again I am biased toward black rays lol.
Got to ask though, how big is your tank? It looks a little small width ways in the 1st picture.. Probably fine but the wider the better if your intention is to breed.
I only have a 24" wide atm as it was for a mini marble male at about 12" disc, Looking for a 30-36" now i have the pearl/leo.
