It is impossible to breed a true "wild" strain from a hybrid strain, but it is possible to breed a fish that has the appearance of a wild strain. In some Countries where they fight betta smaragdina, they would cross the betta splendens into their betta smaragdinas to increase the stamina/power of their fighting strain and cross it back to their smaragdina strain to give it the appearance of a smaragdina yet having the stamina/power a splenden has.
Would that be just another fancy? It might be a far strech but would they consider it as a different species or sub-species ?
Also if you had no outer interference of a wild specimen would breeders be able to selectively breed (let's say a tri colored plakat) to look or be close to the original wild splendens fish that fancy strains started from?
Can this be done with the same fancy fish to get other species in the complex?
Sorry for all the qustions but this is really interesting for me for some odd reason.
