Most wild betta species will breed like rabbits if conditions are right, so you will likely find fry in your tank if neither fish eats the eggs or fry and there is enough cover for the fry to hide from the adults. If you have only a couple of fry and a plenty of microorganisms for them to graze on, they will often raise themselves to a size where they can take adult foods. However, for best results they will need supplementary feeding with foods such as freshly hatched brine shrimp, particularly if there are a large number of fry.
If you don't want your wild bettas to breed, I'd recommend just purchasing a single splendens complex male. There's a handful of species from this complex (a group of closely related species) to choose from, and they are all strikingly beautiful fish. The challenge can be in finding high-quality, pure stock. It seems like lately the market has been flooded with hybrids, and the labelling is not always clear and can be confusing if you don't know what to look for.
Feeding can be tricky. Some wild bettas will eat anything. Others will literally starve themselves to death rather than eat pellets or flake food. It's not necessarily a matter of wild-caught versus captive bred either. One of the fussiest fish I had was actually one I'd bred and raised right here in my fish room. Because of this, I do now try to wean young fish onto flake food as many hobbyists don't want to deal with the hassle of feeding live/frozen.
I do recommend at least feeding some frozen foods. I think you can tell a difference between fish that are only given dried foods, and fix that are fed live and frozen. Feeding frozen foods isn't difficult and I actually use it as a way to get shy fish comfortable with my presence.
My method is such. I have a pair of long tweezers that I use to pick up the thawed bloodworms, brine shrimp etc. with. I then gently tap on the tank, and place the food near the fish. Over time the fish associates the tap with food, and food with your presence, and eventually if you want your fish to come to the front of the tank, all you need to do is tap on the glass.
Another option is gel foods, such as those made by Repashy. I've been trying to get my wild bettas used to taking the Grub Pie variety, and they are actually taking to it better than I anticipated. At first they weren't keen, but I held it in my fingers and got them to nibble at it, and once they realised it was food they were right into it.
