So I have a 75 gallon aquarium with a 14 inch pleco in it. Basically what I'm wanting is to stock the tank with maybe 2 or 3 big fish, and then the rest small fish. Any suggestions? I love the look of huge fish but I understand that im limited by only having 75 gallons. So as big as possible for the big ones, and then on the small ones, I dont care, just need suggestions.
