Abstract
Abstract An aquarium tank having a bottom and four side walls is characterized by a transparent divider diagonally dividing the tank into two physically separate compartments, while maintaining the visual impression of a single compartment aquarium. The divider is vertical, rests on the bottom of the aquarium, and is of a height slightly greater than the level of water in the aquarium. The divider is clear and transparent throughout the major portion of the area thereof, and includes perforate areas adjacent its two ends for passage of water between the two compartments. Resilient mounting members at the two vertical ends of the divider provide a snug fit thereof into diagonally opposite corners of the aquarium. As a consequence of the physical separation of the compartments, newly born fry may be confined in one of the compartments safe from larger predatory fish in the other compartment.
