Gar

These fish are generally piscivorous in the wild, but will take a variety of meaty foods in captivity. Tehrefore, a strong filtration system must be ensured for a healthy gar tank.Housing a 6-inch gar may require at least a 50-gallon tank with width of 12 inches. As the gar grows, it must be moved to a larger tank. The tank length to house a sub-adult gar should be at least 72 inches, but longer is even better. The width of the tank should not be less than 36 inches. (otherwise, the gar may feel uncomfortable making turns while it swims) A minimum of 24 inches of water depth will suit the gar well. Gars are strong jumpers, hence the tank lid should be weighted down.
