The real problem is there is no incentive by either farmers or wholesalers to stop it. As long as they live long enough to die in the tanks of the end customers it's good. Sad but true. This holds true for many farmed fishes now. If a fish lives for say 10 years, you can sell more through inbreeding if they just live 5 or 3 or 2 years, and why stop there 1 year is more than enough. I've often warned about these issues, many fish are just a shade now in color and quality of what they used to be.
But you have a nice female specimen I would encourage you to try and breed quality dwarf gourami's, not with this male, not with another one out of a shop but try to get a male from a hobby breeder. You can breed good hardy wild dwarf gouramies again out of the best specimens.
