I have 1 comet and 1 shubunkin in a 5 gallon tank (dont worry im upgrading to a 10) and whenever it comes time to feed them, the shubunkin always gobbles up all the food, leaving the comet hungry. I had my Comet on his own for a long time before I got my shubunkin, and hes always been an interesting eater. He never really did well going to the surface to eat. Id put flake food on the surface and hed do this wierd thing were hed swim up there, find a flake to eat, and pounce on it really fast and swim away as if the flakes where animals. So, id usually touch the flakes so they would float to the bottom, then hed eat them. Well, now the Shubunkin is eating EVERYTHING. Im afraid my Comet (who is bigger than my shubinkin) may be a hungry fish
