You shouldn't start a sorority until you have a LOT of experience with Bettas. Also, John, you may want to rethink that having "more" is better. For example, having 6 goldfish in a 2.5 gallon container is WAY too much. Goldfish need at least 20 gallons EACH to reach adult size. Ask anyone on this site, they will tell you the same thing.
