I love the idea of a betta store! A place where people can come and can actually trust that the person working in the store knows what they are talking about and that the items they are buying won't kill their fish? There is a market for that. Definitely. You could build relationships with some of the breeders on here and maybe be able to order requested bettas for your customers.
I get the excitement in coming on here. I love my fish, my tanks, and learning new things about this hobby. I used to live with someone who also shared my interest in it. Now I don't, and it is nice to be able to come here and people get it.
I also understand how it feels to have people think you are a "crazy fish lady". Don't let it bother you. Everyone has things that they enjoy and it isn't going to be the same person to person. Some people have an obsession with shoes, or with cars, or with dolls... Don't let other people put a label on you and carry around the weight of it. If this makes you happy, then enjoy it. You aren't hurting anyone and you aren't making someones life worse.
Taking care of these fish is therapeutic in a lot of ways and can help you focus on good things, rather than bad. It is nothing to be embarrassed of. Create beautiful tanks and raise happy fish. Do it all regardless of what people say, and with a smile on your face. As long as you are enjoying it, the ones who love you should be happy for you.
Whew. That's my opinion. Take what you want from it. Know that you can always come on here and be understood.
My lovely bettas are: Dagger, Egg, Salsa, Marble, Augustus, Miles
Puddles, Oz, Nate, Monkey, Picasso, Feng, and Maui
