Armored Catfish (Hoplosternum littorale) are $15 each, plus shipping, and are a good choice to stock into warm water ponds and aquariums. These catfish (~6-8″) are hardy and easy to keep, tolerating warm temperatures, crowding, low dissolved oxygen, and they are not picky about foods. I think these are one of the most interesting fish species I’ve kept. They show social behaviors with each other, slash at the surface when breeding and reproduce via building a temporary, floating, bubble nest. They can be stocked with other fish and are not aggressive towards other species. Contact us at email@example.com to order and arrange shipping.
