Abstract A terrarium/aquarium having a light-transparent shell forming a moisture-retaining enclosure about a region containing plant growth medium. Transparent jackets mounted on the shell form with exterior wall portions of the shell, water-bearing chambers for raising fish. Water in each chamber is separately circulated and filtered, with the circulated water flowing through a conduit extending through the medium to exchange heat therewith.
