while we should protect the species we have in the hobby it is listed as Vulnerable not extinct and from what I hear getting the eggs to hatch is not an easy task so producing hybrids is pretty low on the list of fears. Dstuer has gotten eggs on multiple occasions but no fry that I am aware of. I think ciclasoman (Jose) has breed them. He has breed most Maddys so if you are looking for breeding info those would be 2 great sources.
Oh and Rare Dave has some in stock now I believe.
