Interesting... Are these common fish to have in a tank? I traded my fat clown knife for these two guys and a 10" bala shark I hope I got a good deal....
They get pretty big and eat just about anything you throw at them. You got an okay deal. The 10" bala is nice, the two golden sharks are common. You see them at pet stores small and within a couple months they are huge 10"+ fishes... I think the person you traded may have got the upper hand though. But if you like em who cares?
