Scott, I'm not aware of any large commercial breeding operations that involve cardinal tetras. Neons yes, but cardinals are a whole other thing to try and breed, especially on a large-scale basis. It's always been this way and that's why cards continue to be taken mainly from the wild. Hopefully this will change and cards will become captive and commercially bred, but the cardinal has been in the hobby for some time and there still isn't a successful method designed for producing them commercially. I really doubt that there ever will be, but it would be very beneficial if the available cardinals were captive bred. In my opinion they are much better looking than neons.
