While color change is perfectly normal with goldfish, black usually isn't one of the colors since it is a very unstable color. How long has the tank been setup? Is it cycled? Check your water params, high levels of ammonia can burn the fishes skin and when those burns heal they turn black, kind of like a bruise on us. When the burns heal it means that the ammonia isn't as high but in a cycling tank after the ammonia starts to lower the nitrites go up and they are just as deadly as ammonia. In a cycled tank both the ammonia and nitrite should always be zero and the nitrate shouldn't be more then 20.

Nothing is wrong with your goldfish. Most reds, whites, and goldens end up turning into black. Your gold fish must be changing colors as he matures and that just reflects the quality of his breed (the less black the finer - unless he is a moore or a shubunkin) so don't worry. Enjoy your goldfish and look forward to what he ends up looking like eventually.

the black moor isn't rubbing off on your goldfish -- it could have black spot disease which will go away by itself if you keep the water clean. it could also be growing up. goldfish change a lot as they grow. it might be what they call a calico or spotted goldfish and it was just plain before.

It could be possible that your fish has got some kind of disease on it. I would go to the pet shop and ask for a solution to put in the water to help it.

Check your ammonia levels in the tank. They should be 0 ppm. Could be just changing colors as well.

If it's acting OK otherwise,it's probably just changing color.Goldfish do that all the time.It's weird,but it happens.
