This would make the tub larger then his tank :ROFLthe way i would do it is get a large tub about 4 ft long 3 to 4ft wide have a battery powerd air pump and have a blanket or over the top with the edges on the floor weighed down with bricks driving carefully and since the fish is 3ft your gunna need a tank way bigger then the 125 like a 400 8x3x2.5 or a 450 8x3x2 its already way to big for your 125 what is it 18 inches wide and the fish is 2 times that length it wont be able to turn around properly
ok guys listen to me ... i live in jordan middle east we DON'T have big tanks my 125 is one of the biggest tanks in the hole kingdom so NO ONE gonna buy this arowana cuz there is no good tanks for it so that the fish store make it price cheap i can't let this arowana gone of my hand it ****ing beautiful and i can house it good
and it can turn around in 15" wide i saw it turning perfectly in the store so it will not have any proplem with my tanks since my tank wild is about 20" so its ok
and to any body who say let it meybe someone can buy it who can house it in bigger tanks .. as i told before there is no bigger tank in my country
so thank you guys i'm gonna buy the half of it price and leave it in the store for ten days so i can fix my 5000leter filter
and i will move it in white bag ( a huge white bag )
If this is truely the case, then the best thing would be to put down the arowana humanely and outlaw the importing of arowana into your kingdom.
