This comes with everything you need for a large, or several, reptiles: a HUGE tank (48in x 18in x 25in tall), heat rock, heat mat, heat lamp, substrate (new), hammock, fake boulder 2 thermometers, fake leaves, and a driftwood platform. My bearded dragon has been living in it for several years, but unfortunately I can't keep him anymore (dragon is listed separately for $0). It was originally a fish tank, but I can't guarantee water tightness and it's been several years since it held water.
