Common, you have the extra money to build a moat around your house don't you? You can add a drawbridge while your at it. I mean at least build a 60,000 gallon heated pond for him outside... it's the least you can do!
I'm a carpenter , standard height for doors here 6'8" or 80" ,how wide do they get[ the fish that is ] ? pretty big fish WOW . How much would it weigh ? anyone know ? Don't blame you for wanting to return it ,ste , it's going to be a big dude, a man eater too , holy crapp .80" these days I like to keep my guys under 8" like 4" under 8" .
well, I'v got no idea how much it will weigh but If it can eat someone, i'd gues that it must have a pretty wide mouth. i'd guess at around 18" maybe a little more but it could open its mouth bigger to eat bigger prey such as people. Believe me, I'd love a moat round the house .
