PetSmart definately rules out of PetSmart, PetCo, and LPS. I've never been to walmart, and have no desire to go. PetSmart has limited tail types, but usually has some nice colors. I saw a dalmation the other day, and I got my Yellow and Blue VT there. PetCo has many tail types, but the employees there were annoying me (they were telling me that bettas should live in small tanks,and they don't like heaters) , and the water was dirty. LPS lets you take orders (I comtemplated ordering a pure white halfmoon male, but I saw Louie, my blue and yellow VT at petsmart and bought him. =P) but the bettas are kept in glass jars smaller than petco's, and they don't have lids. One of the small containers has 6 peices of uneaten food in it. The poor betta wasn't looking too hot either.
