Precisely how not to keep a betta. Unheated, boring, too small. These fish are tropical, love to swim, and are intelligent and curious. They will do much better in a larger, heated aquarium with lots of plants to interact with.
Self Cleaning Betta Aquarium - Simply pour fresh water in, and dirty water is expelled through a tube and out of the tank while your fish swims happily within. There are no filters, batteries, or cords. by cecile
