What is the minimun and what would be the optimal size for a jaguar tank? I've done a few searches and nothing came up. I know they grow to be about 16-18 inches so the tank would atleats have to be 18 inches wide at the bare minimun but preferably 24. I have heard some people say 240 for one but that seems a bit big for a fish that grows to be less than 20 inches. Could someone please explain this to me? Cause i dont want to get this guy then run around trying to find a tank to upgrade him in i'd rather have the rite size tank from the begining so i have less headaches. Thanks
