Just bought the tank new a few months ago for $60 but we got more fish and had to upgrade. Includes everything it came with: tank with lid, light with several different colors, and filter. I threw in two new filter pads but admittedly the filter leaks out the top a bit so I was using a different one, it could probably be patched with some silicone. Also included are a bunch of extras: rocks, decorations, heater, both betta and goldfish food, a few cleanings worth of water conditioner, as well as the extras that came with the 10 gallon tank I bought used. I was told everything worked but haven't verified as they need tubing: air pump for a sponge filter, and a water pump for changing out the water. Just add fish and you're good to go!!
