First off, no bowl is nice. No fish should be kept in a bowl, but most of all, not goldfish. Goldfish require a minimum of 10 gallons of water per fish, with filtration and proper water changes and cleaning. You haven't mentioned what this "black" looks like. Does it look like something "on" the skin, or does it look like something "in" the skin? If it looks like it is "in" the skin and the skin otherwise looks healthy, it is probably just doing some color changes, which goldfish almost always will do and there is nothing to worry about. If it looks like there is something "on" the skin and if the skin looks damaged, then it is probably ammonia poisoning or some other disease, such as melanophore migration, but it is difficult to say without more information. And treating the wrong disease with the wrong medication will do no good. If it is still acting healthy and eating, maybe it is just a color change. If it is a disease, then the happy and eating is a good sign as well. You need to look more closely at the "black." If the skin looks damaged, try adding a little aquarium salt to start with. Do not use table salt. Do not add it directly to the water, pre-mix and do not use too much. Add it according to directions. This will kill the disease, if any, repair the slime coat and relieve stress. In the meantime, you must get a minimum of a 20 gallon tank for your 2 goldies. And remember, when it grows to over 4 inches, it is time to think about getting them a 40 gallon tank. Also, you need to learn how to test the water for ammonia, nitrites and nitrates, because the black could be a sign of ammonia poisoning which could kill your fish if you don't learn how to get it under control. Good luck to you and your goldies!

Sounds like he was in water with very high ammonia and it burned his tail and is now healing. I really hope that bowl is at least 20 gallons big with a very good filter otherwise you are overstocked and are killing your fish. Please learn the correct way to care for your fish if you plan on keeping them alive. Unlike what most people think that can't survive in a bowl, no fish can. Here is a great website with loads of info, you can even join the message board if you still need help with something, http://kokosgoldfish.com/
Ick is a parasite that looks like the fish was sprinkled with salt. No fish can have too much water. And yes goldfish can and often do change color but black is very unstable and fish normally don't turn black.

That's not ick and if you add iodine to the water it will kill the fish. Goldfish need 10 gallons per 3 inches of fish because they release toxins into the water. What you are describing is ammonia burns. You need to get this fish some new water. You should change 100% daily until you get a bigger tank.

likely, from all you defined, something aggravated him which led to the spazzing and the black. Black spots or marks like that are elementary indicators of ammonia burns on fish. The black is relatively the healing point however. i could first examine your water high quality, make valuable ammonia and nitrites are at 0 ppm. i be attentive to the Jungle Labs form of water dechlorinator is named start up ideal. i've got used it formerly, no longer my popular, yet could be high-quality and should no longer be an argument. so a techniques as i be attentive to, this is the sole product they make that eliminates chlorine/chloramines. Is that the type you have? i'm valuable they make different stuff as nicely for different issues, are you valuable you probably did no longer by danger grab something that wasn't a water dechlorinator? because of the fact chlorine/chloramine poisoning will additionally do an identical which you defined. He could be high-quality however.

It's natural. my goldfish had some dark orange marks on its head then they dissapeared. No need to worry if it acts normal or if the black isnt bumpy.
