Cuban Gar

About

Cuban Gar (Atractosteus tristoechus) is one of those species that demands a frank conversation before anyone considers acquiring it. Native to western Cuba and Isla de la Juventud, where it inhabits rivers and lakes, this animal is known locally as 'manjuari' and carries genuine cultural significance in its home range. It also carries endangered conservation status, which alone puts it in a category that deserves serious thought. Gars as a group rank among the most ancient lineages of fish still swimming today, and this species exemplifies that heritage. It possesses a modified, vascularized swim bladder connected to the pharynx that allows it to gulp atmospheric air, much like a primitive lung. Adults are ambush predators that target other fish and reportedly even birds. Juveniles occasionally surface in the aquarium trade, and some public aquaria do maintain the species successfully over the long term, which is really where it belongs. The eventual size alone, we are talking about fish that can push past four feet, sometimes considerably more, rules out virtually any private setup. Temperament is broadly peaceful toward tankmates it cannot swallow, but the sheer scale of this animal, its lifespan, and its conservation status make it a species most hobbyists should admire from afar rather than in their living room.
