I have an orange parrot and I gotr him, my other fish, and fish tank this week. I just noticed he seems to be getting black marks. I just saw them today. It’s on its lips, more what looks like dirt on its back, like 2 small black spots under its belly, and blay streaks on its fins. He’s seems to be the more aggressive or dominate one of the grope so far. Do the dominant parrots turn black or something? I would appisheat any help...thanks!
