ABSTRACT:
A fish tank vacuum, for use with a fish tank having a fish tank interior and an intake pipe, for removing debris from the fish tank interior with a suction nozzle. An attachment assembly connects to the intake pipe for establishing water flow into the suction nozzle. The suction nozzle is attached to a filter housing that holds a filter disk. Swivel assemblies are connected to the attachment assembly and the filter housing. A flexible tube extends between the swivel assemblies and allows the suction nozzle to easily move around the fish tank interior for debris removal.
