GAR you looking for a unique fish that is a blast from the past, almost a living fossil?! Why not consider a fish like the Gar?? Fish like Gar first appeared over 240 million years ago, and these prehistoric-looking fish are still going strong today!! These fish can grow to very large sizes, reaching upwards of 2.5-6.5 feet in length! These fish are active predators and will require live foods, as well as a tank or pond of appropriate size- approximately 4ft x 8ft to allow the Gar space to move and turn around as they are not very flexible fish!
