The Gar Pike (Belonesox belizanus), also known as the Pike Livebearer, is a long, predatory fish native to slow-moving freshwater and brackish habitats of Central America. Despite its name, it is not a true gar but a livebearing fish closely related to guppies and mollies. Growing up to 12 inches, it requires a spacious aquarium with open swimming space, a tight lid (as it may jump), and strong filtration to maintain pristine water. Gar Pikes are ambush predators and should not be housed with small tankmates, which will be eaten; instead, keep them either singly or with other large, robust fish. They are carnivorous, feeding primarily on live prey such as feeder fish, shrimp, and insects, though some may adapt to frozen foods with persistence. Breeding is possible in captivity, as they are livebearers, but fry survival is low without separation. Due to their size, predatory nature, and dietary needs, they are best suited for experienced aquarists.
