I will be getting tilapia in a week or so and the person I am getting them from lives about an hour away. I will get about 100 fish. Will a 32 gallon tub with a good aerator and top on it do the job? The fish will be about 2 inches long. What is the best way to get the water temperature in the tank to match the water in my big tank at home? Any information will be helpful. Thanks Ricky.
