I am not happy with the color of most of the fish. I have found with Phil recommendation better food than the Otohime. I have ordered them and will start feed them with this new food as soon as it arrive. Will see if it improve the color. There are some deformities. I will need to do more water change and will try only to raise a small number of fish at a time. I think this will correct the problem. This is my first try at this. It is a very steep learing curve.
