Ok, thanks Jim. I knew that Muskie for the "home aquarium" advertising was just a little bit sketchy. I can construct a tank at just under 270 gallons (6'*2'*3*). How many full grown walleye do you think I could healthily hold in this tank? I am guessing I would also have to create a low light environment for the adults. Wow, this sounds hard. Maybe some largemouths would be better.
