Care Guide
Diet
Florida Gars are obligate carnivores requiring a diet of live or frozen fish, shrimp, and other small aquatic prey. Feed juveniles small feeder fish 2-3 times weekly, while adults require larger prey items 2-3 times per week. They may eventually accept frozen foods but prefer live prey.
Behavior
Florida Gars are solitary, ambush predators that spend much of their time cruising slowly through the water column or resting near plants and structures. They are highly aggressive toward other fish and will consume anything small enough to fit in their mouths. These fish are relatively inactive but require ample swimming space.
Breeding
Breeding Florida Gars in captivity is extremely difficult and rarely successful in home aquariums. They require very large tanks, specific seasonal temperature fluctuations, and spawning substrates. Commercial breeding is limited, making captive-bred specimens rare.
