Need help. I've got a great juvenile Imperial Angle. Great little guy. Swims everywhere eats good. And spends way too much time with the cleaner shrimp. In fact so much that his color seems to be faded. Like I said everything else is great. Eats, swims and no signs of illness other than obvious color faded. Could the cleaner have cleaned too many dead scales etc.? Everyone else in the tank is healthy and doing great. Water is good. Any ideas? I'm beginning to think he's like the sun tan lady up north. He's over doing it.
