Ok so you are saying that they are taking a wild and reintroducing with a domestic one. I would think that it would be hardier than the wild one. IE more prone to except tank conditions vs wild conditions. But by mixing it with a wild it has made it so that it has genes that are less likely to have birth anomalies. (IE odd fins, etc).
SO in other words just fyi Usually:
wild = better genes, harder to keep in tanks. (IE needs water and food like it was living in.)
domesticated = Easier to raise in tanks. (IE hardier in the sense of likely will eat flake foods and other dry foods, and can tank a higher range of ph and hardness) but more prone to birth defects and obviously hybridization.
