Hi, I'm looking into purchasing a Bearded Dragon for the first time. I have had a Green Anole, and had a 10 gallon tank for him. I know that a cage that size will not be big enough for a bearded dragon, but I'm wondering (in gallon tank sizes) which one would be the best for a Bearded Dragon. I keep seeing measurements on websites, but those are of no use to me. I need simple terms. Also, since it would be my first time owning one, I do not want to spend an exorbitant amount of money on a cage for one. I'm wondering which cage would be the best for a first time owner, but will not cost me a lot. I really don't want to spend more than $70 if possible. I know that might not be possible, but that's my goal.
