I have one penguin tetra which has been acting a bit weird the last few days. It just stays in one place near the bottom of the tank an its marking are a lot more dull than the others. Of particular notice the black part on the tail is a lot more faded compared to the others but doesn't appear to be rotting nor do I see white spots. Any ideas whats wrong with it?
