Huh, so this is weird. My boyfriend is just getting into fish keeping and for his first fish he got a four or five itty bitty feeder comet goldfish. One was calico..up until two days ago. He had black and dark orange splotches on his orange body, and then suddenly the other morning he is now just orange with a creamy white belly like always, but his black and brown is completely gone. I have never, never seen anything like that happen before. I am not worried, just curious. Anyone have any ideas?
