However, just

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.

Gars are hardy fish. They have the ability to breathe atmosphere air by means of vascularised gas bladder that act as lung. They are generally peaceful, usually keeping to themselves and not disturbing others. Hence, if space allows, they can be kept in a group. Large gars are capable of inflictin
