Yesterday, I came back from a 2 day trip. When I came back, all 3 of my KK parrots were hiding in the corner. In the begining they would hide and not eat. But 10 min later they started to eat. Also, I noticed that one of the smaller KK parrot fish was losing its orangish colour. I thought it was sick but then I looked at the bigger one and he was not that orangish. Then, today, I saw that the fish is more orange. Is it natural, or are they sick.
