Aqua Farm - Self-cleaning fish tank that grows food. Fish waste feeds the plants. Plants clean the water. Includes everything you need to get started as well as organic seeds and a discount coupon for a Betta fish.
According to MarthaStewart.com, anubias can be fully submerged underwater. This plant keeps water algae free. Another opportunity to have a fish friend :) http://www.marthastewart.com/270708/indoor-water-gardens
