Hi! I have had my red cap oranda goldfish for just over a year now. I used to have him in a 10 gallon tank (I know, way too small) but I upgraded him last month to a 25 gallon tank when I moved to my new apartment. I also have a 50 gallon filter. I know that orandas begin developing their wen between 1-2 years of age. However, my oranda has shown no signs of his wen developing. In fact, the orange (red) coloring on his head has almost completely turned white. It doesn't look like a bacterial infection or anything and he seems healthy. Also, I had my water tested recently at PetSmart and they said that all the levels are fine. Is this color change normal? Will it go back to orange (red) and will he begin developing a wen? I just want to make sure that he is growing healthy. Thanks!
