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. Also, they are always scared of the bubbles and my dad left the bubbles on so did they get traumatized from the bubbles or was it somthing from growth. This isn't that regent but I just want to ask. Thanks for the help. I really apreciate!!
