The Alligator Gar (Atractosteus spatula) is a large, freshwater fish native to the Southeastern United States, primarily found in the Mississippi River Basin, Gulf Coast, and parts of Mexico. Known for its unique and ancient appearance, this fish species has an elongated snout resembling that of an alligator. With fossils dating back over 100 million years, it is often referred to as a “living fossil.” This majestic and prehistoric fish species is coveted by advanced aquarium enthusiasts for its fascinating size, striking appearance, and incredible longevity.

Due to its large size, Alligator Gars require spacious tanks with appropriate water conditions. Juvenile Alligator Gar can be kept in a minimum 150-gallon tank, but as they grow, a larger, specialized tank (over 1000 gallons) will be needed. Alligator Gar is a carnivorous species and feeds on a variety of aquatic organisms, including fish and amphibians. With its robust health and longevity, it can live for decades when provided with the proper care.

Due to the size and specific needs of the Alligator Gar, this fish is not suitable for all aquariums. It is best kept in large, species-specific tanks or with other large, non-aggressive fish. If you are an advanced aquarist with the right space and resources, the Alligator Gar will make a truly magnificent addition to your aquarium.
