i see color in all of them. my caribe lost all his color due to stress when transporting him. he was all white and had his black dot. put him in a hospital tank and a few hrs later the red came back, 2 days later and he is fully colored. maybe its just stress.One of my nats has lost most of its color while i was on a 4 day vacation. There is nothing wrong with its eating or attitudes. It is intreseting that only one of the 35 nat.s has lost its color. I am awaiting for your feeds.
