To set up my pacman frog's tank cheaply, I used a 10 gallon tank I had available, Eco-Earth, a long skinny rock I found outside he can sit on (he actually seems to enjoy it, weirdly enough), a glass food storage container for a pond (lined with little stones so he can hop out easily), and a bro...er...bromillead? However you spell that plant. He uses the plant as his hide by sitting under the leaves.
