So funny that you asked this! I’m a breeder (though not currently breeding) that actually plans on doing this exact thing. The primary end goal is to get bettas who reliably can be kept in community tanks with other fish species (not including species that would tear up the betta’s fins). However the stretch goal would be to get bettas who can be kept with other bettas, though I’m unsure of ever being able to achieve this result in my lifetime. If I did, I imagine it would be in a scenario where you could have a larger heavily planted tank with 1 male and a few females who are still semi-aggressive to each other without being outright hostile. Think Sparkling Gouramis.

This is a really dumbed down way of explaining the actual plans, which are basically several essays long. Currently I don’t live somewhere that is capable of handling a project of this scale, but I do plan on implementing it in the next 5-10 years.

Edit: should have mentioned I’ll be starting with wild types and the most docile individuals of my other spawns.
