The Fish ‘N’ Flush is a 2.5 gallon aquarium that replaces your regular ceramic tank. It consists of two pieces: the actual fill tank, and the aquarium, which surrounds the fill tank for the “fish in your toilet” effect. This is great product for the pocket fishermen and people who can’t keep pet fish alive (as it comes conveniently located atop a fish cemetery). It was designed by Richard Quintana in 2005 and retails for $300.00.
