I am completely new to the saltwater hobby. I was wondering what is the minumum size that you can use in this hobby. I bought a used oceanic hexagon tank, used from a friend of a friend. I don't know exactly how big it is but the tank is in great shape and the stand was included in the deal. Anybody also know anything about older oceanic tanks? Its a very heavy tank for its size, if I had to guess size I would assume slightly over 40 gallons. Any help is appreciated. Thanks!!
