I have a tank that is 125 gallons. It’s 72 inch by 18 inch by 24 inch. I have it running with a fx6 with a rose queen, red Texas and Florida far in it. Those fish will be moved to a different tank shortly and I was wondering what to stock the tank with. I wanted to do Arowna or peacock bass but I’m pretty sure the tank is to small. What should I put in the tank. I don’t want to do tropical fish though.
