No offense, but this statement is false. When the water temp hits a certain temp, usually between 58-62 degrees, the males sense that it is time for the females to spawn and a hormone is released, turning them a dark purple, almost black. This is why they are so agressive. Once the temp is right and the beds are ready, the females come in and spawn, then they quickly move back out to deeper water. They dont stick around long enough to get a "tan."
