Abstract
Disclosed herein is a modular aquarium apparatus generally comprising a watertight housing which suspends a glass thermometer safely therein. The housing includes a ballast chamber carrying a weight of predetermined characteristics sufficient to provide the housing with sufficient negative bouyancy such that the housing, without more, will float at the top of an aquarium with the lower portions of the housing submerged. With the addition of a special sinking sub-assembly carrying additional ballast the aforementioned thermometer housing may be converted into a sinkable housing for measuring temperatures at the bottom of the aquarium. Alternatively, the housing may be provided with a special cap and hanger arrangement for converting the housing into a hanging thermometer assembly adapted to be suspended from the upper wall portions of an aquarium tank.
