Like stated above its a debatable topic. That beibg said I had my corns in the same tank for the last 17 years. They were from the same clutch and stayed around the same size. I had a tank that was also very big 6 foot by 3 by 4. There was 4 hides in there with two diffrent hot spots.. yet they were always in the same hide together. The only time i seperated them was feedings. One died this spring so now the other is all alone now.
