I would not keep more than 2 bullfrogs in a 40 gallon. I would prefer a larger tank for more than one frog really. Both male and females display territorial behaviors. You treat the water in the tank like you would a fish aquarium. In regard to cycling, partial water changes and filtration.
If you keep more than one bullfrog they must be very close to the same size. They will try to eat anything they can get into their mouth. Even another bullfrog.
As for how expensive it is. Well an adult bullfrog can eat a lot. You can save money by buying a lot of crickets online. If buying from a pet shop it can become pretty expensive. Breeding your own feeders will make it much easier on your wallet though. I breed roaches. I used to breed crickets too but they stink, are noisy and I don't like keeping them.
A lot of people will feed mice to their bullfrogs. However a staple diet of mice is bad for them. It should only be a treat. I would also suggest prekilled mice. Personally I do not feed mice at all to my frogs.
