Dark substrate, tannin stained water, plenty of plant cover, and dim lighting will give you the best behaviour and colouring in most species of wild betta (I believe some species do come from more clear water environments but these tend to be mouthbrooders).
Also the top of the tank should be completely covered. This means no spaces around cords or tubing, or holes for feeding. I use cling wrap for smaller wilds. I would have to say jumping is probably one of the leading causes of death for wild bettas in captivity.
I'm a purist, so dislike hybridisation. However, if you do hybridise your fish and sell them on, please specify as clearly as possible that they are hybrids. This is my biggest issue with hybrids. Some of these species are highly endangered in the wild, and you don't want a breeder accidentally introducing hybrid blood into an otherwise pure line.
