Hi everyone. I've got a 20 gallon high aquarium sitting in my garage. It originally housed a gecko, but now it's empty. The tank measures 24x12x16. I know that tall tanks can't support as many fish as a wider tank of equal size, but if I was hoping to turn it into a small planted community. Could the tank support a school of cory cats and a school of emperor or black neon tetras. And if so, how many of each? Any advice or suggestions on how to get this tank going would be appreciated. Thank you
