The White Sturgeon, the largest freshwater carnivore in the world, with specimens maturing at over 10ft in length, and weighing in at an excess of 1,000 pounds, in captivity are raised on approx. 45% protein as juveniles, and 40% as adults. As a cold water species they require a high fat content in their feed (for energy requirements, and to spare protein use in that regards) , but even this majestic long lived carnivore does not require anywhere near the 60% protein level that some amateurs feed their flowerhorn, which at best, is an opportunistic omnivorous group of fish.
Unfortunately, as a good friend of mine explained to me years ago, you can't stop stupid.
