I would say no. There isn't much that is left to discover about them. Wild species maybe. But honestly, what would be the reason?
I could never have fish keeping as a job. It's a hobby to me. My teachers have told me to go into it being a profession but if I do I'll probably lose interest which is something I would hate to do. So for me, no I would actually hate keeping and researching bettas as a profession.
Who am I? Well I am a Junior Member of the International Betta Congress and a breeder of white HMPKs, red dragon HMPKs, black/red dragon HMPKs, metallic multi HMPKs, blue masked HMPKs, and now multi color HMs. Soon to add black HMs. I will be showing in New Breeder class in fall of 2012.
