Do they have a good selection of betta fish?

Yes They Do I Remember seeing I good Variety of them on my last visit also they tend to have some of the fancy species as well.

I don't recall seeing a bunch of Betta fish. That being said, this is probably one of the most impressive stores I have ever seen for aquatics. Just because I didn't personally see it doesn't mean they don't have a nice selection. I went there for other things. I can say that every freshwater specialty fish I have wanted or considered they actually have here as opposed to being only able to find them online. They have anything and everything, and especially the hard to find things from specialty substrates to the rare almost never replaceable bio wheels. I remember seeing some Bettas in some of the community tanks. If you plan on going today there is a sweet girl that works on Sunday named Mariah, and she has purple hair. This chick will be able to tell you everything you want to and need to know as well as be able to show you where to find what you need, and she will give you all the time in the world. I hope this helps. If you haven't been I suggest atleast walking through the store!

Yes they have a decent selection of Betta Fish.
