First of all, they aren't being bred in captivity.
Some tangs like the regal are being captive raised after having collected the pelagic state in the ocean.
One naso needs a large tank, but two would need a VERY large one. A 125 is definitely not large enough for two.
I don't know who you would get to identify a male and a female. I doubt that there are too many people out there that could, if any.
