Highly doubt it has ever been done, because...
1 - it wont happen in the wild because they are in different water basins.
2 - Captive breeding in fish farms is very unsuccessful (if at all) so I doubt anyone has bothered trying to breed two different species as that would be 10x harder then breeding 2 of the same species, which seems hard enough as it is.
So my guess is that it has never been done, but if you are asking if it ever will be...... then I guess only time will tell.
