An aquatic device includes a support post including a first end and a second end, and a platform assembly secured to the support post for movement relative thereto. The platform assembly includes a platform member shaped and dimensioned to extend transversely to a longitudinal axis of the support post, a float member and a central support member to which both the platform member and the float member are secured. The central support member includes a passageway extending along a length of the central support member. The passageway is shaped and dimensioned to fit over the support post such that the platform assembly may freely move along the length of the support post. When the aquatic device is positioned within an aquarium with the support post extending toward an upper surface of water within the aquarium with the second end of the support post extending near or above the upper surface of water within the aquarium, buoyancy of the float member causes the float member to sit at the upper surface of water wit
