That's where my school is as well. :) If you want an option other than petsmart to find fish locally you might check out Exotic Underworlds they don't carry special tail types but sometimes you can find nice bettas there (other times not so much).
Oh dear I may have to visit that place. Ohhhh they have reptiles too :) hmm... <3 oh excuse me, I must control myself! Ohhhhh no they have green tree pythons, oh I might just cry now. I'm very happy.
If I don't get a betta there, at least I might get a reptile or supplies when I get out of school if I choose to stay there.. :D
You should check it out. It is so cool and the guys are all very nice (despite the fact they know nothing about bettas). I love going in there to look at the fish and the reptiles.
