I have a very young ryukin about an inch long and it has no hump yet. It has very nice color and when it gets bigger I think it might win some competitions some day,but it can't if it looks like it's sick!! See my goldfish has a red face on it and the gills,there regular. I don't use any water softeners or ati stress fluids. My goldfish always is just hanging on the top of the tank trying to eat the bubbles or something. I use an airator that very sufficiently supplies oxygen. There are no chemicals in the gravel I have and he only has two other tank mates. There all in a ten gallon tank. I change only about 30% of the water at a time and I do it adleast 1 time a week. His other tankmates are so lively so I'm pretty sure its not the water quality beacause then theyed all be affected ,right? Now,some parts of his body are loosing it's color and turning pink. I feed them a liitle food twice a day,but the problem goldfish isn't really that exicited about eating. What am I doing wrong?
