Great. Rice paddies. Bettas live in rice paddies, too. But do you see any of US recommending that they be kept in tiny bowls with no filtration? Would any of US stick a male and a female together in a two gallon bowl when they could very easily be aggressive toward one another? No!
If you're already so hell-bent to do what you're trying to do, then why are you asking us about it? If you HAVE so much ruddy experience, why are you asking to talk to someone with experience and then immediately waving them off when they give you advice that's different than what you're wanting to do? In this situation, no one's going to give you a pat on the back if that's what you're looking for.
