Go buy a large rubbermaid tub (40+ Gallons) from Wally-World. They're like 8 or 9 bucks. Fill the tub about 2/3 full and add some flat rocks that come with in a few inches from the surface. Now you have 2 choices on filtration. Buy a cheap filter and do a 25-50% water change a day or buy a really good expensive canister filter and have less water changes to do. Get a submersible heater and keep the water around 78 degrees. For food feed it Reptimin, freeze-dried shrimp, shrimp pellets, crickets, small snails, frozen shrimp, fish fillets and earthworms. Don't bother feeding it live fish. If I lived closer I'd take the snapper off your hands.
