I guess I was wrong, the longer he is in the tank the darker he is becoming... he is nearly completely black... or a very dark slate gray color. Maybe this is the dark black variant after all? I just got some juvenile peacock bass, once they hit the 5 inch mark or so I will place them in a more aggressive tank. I had 2 before but they didn’t last long, they were smaller and seemed to waste away. These seem much more stable.
