Any fish should get as big in a display as it does in the wild. If it doesn't, you're doing it wrong. It's that simple.

yeah and temp,food,lake/river size plays a role in the sizeclassic-chassis;3390136; said:Did you get that from a thai fishing site?
In the mentioned lake the grow massive because they always have plenty of food. It's a big over stocked lake with many species of fish that breed. Some seasons you cannot catch them because they're not interested in the bait, they're too full on fry. They slap the water with their tails to stun smaller fish then eat them all. I think that is about 9 foot if you try to imagine the blond bloke laying down next to it he must be 6 foot tall.
