A place that stocks 65g

[Enigma]

Big Al's has a good selection of the Perfecto/Marineland tanks. I'd phone them first, though. They also have a nice selection of tanks with stands and hoods. Once again, phone them first (it could be a long and frustrating trip otherwise).

Pisces could have some too, but if you phone them be sure to ask what brand of tank it is if they have a 65. I personally won't purchase the tanks they have made for them by a local builder (which accounts for a lot of their stock).

Petland also sells tanks, not sure of their prices, but they do just sell tanks without lights and other equipment if that's all you are looking for.

Thanks for the advice everyone, time to start doing some digging around!
