I need advice. I am getting a new tank tomorrow and I considering getting a gar. I'm just not sure which type would be best for my tank. I'm purchasing a used tank for $150.00 and the measurements are 72"W X 18"D X 24"H. The guy said this is approx. 140 gallons, but I am not sure of this. Of course it will be a while before the tank is ready for any new additions, but I would like to be thinking about my options. While tank is in process of being set up and cycled I should have plenty of time to locate just the right fish. I will have to come up with a stand, lighting and filtration before I purchase any new fish. I am in Alabama and we have spotted and longnose gar in the Cahaba River locally. I have seen them several feet long, not far from my home. How feasible is it to catch a juvenile wild specimen and acclimate to tank?
