I live in Wichita, KS and I am having issues finding a good shop that actually knows something about bettas. Our old shop that was around before I got my little Jean-Luc was really good (my CA literally swears by it), and when I went exploring to find this rumored place I went right past it and then had to back-track only to find out that it was for sale

.
So, I am stuck using PetSmart that literally does not have a clue what it is talking about (except for the lady that helped me pick out my little Jean-Luc), and the aquarium store that only specializes in tropical fish but don't know anything about bettas (

Can absolutely anyone PLEASE recommend places for me to go that acutally know a thing about Bettas? This is my first time EVER having a fish and I really need experts who can help me so I don't have to continue to become completely overwhelmed everytime I walk into PetSmart looking for fish supplies.
Any advice is DEEPLY appreciated
