Is it normal for a flowerhorn to dominate a tank. I have 100g that he shares with Midas and Jaguar among others. He used to be shy when he was younger, but now he owns the tank. Aren't jags supposed to be more aggressive? They're still all pretty young. The flowerhorn's about 5 inches, Midas 4 in, and Jaguar about 3 in. Will the Flowerhorn always dominate or will this change in the next few months?
