The gold fish turning black could be due to many reasons, such as over feeding, too much ammonia, poor water environment or parasites. Make sure you change your water and get special salt to your water as well which will kill the parasites.

There are some fish that change colour over time like cichlids, but it is common in goldfish as well. Test your water and look at the pH levels to see if everything is kosher. If youre uber concerned, talk to a "pet care specialist" at Petsmart. Good luck to your <")))><!

Your water has extremely high ammonia content. Their scales are being burnt. If it starts to burn their gills, they'll die a horrible death. Although goldfish are quite hardy, they cannot survive this type of water condition long. You need to reduce the number of fish in your tank or increase the size of you're tank. Change 15% of the water immediately. Get a pump that is for a tank at least 10 gallons greater than yours, add ammonia chips to the activated charcoal in the filter or put some in a old nylon, tie the end closed and put it where the pump redeposits the cleaned water back into the tank and also add some salt to the water - even for fresh water fish/goldfish. For a 30 gallon yank, add a teaspoon every other day for 4 days. It'll help then build up a slime coat so the ammonia won't burn them. Go light on the salt - maybe split it in half and put it in twice a day - their burned scales have to be painful. Salt isn't going to be nice at first but as their slime coat builds up will be a huge relief

Change some of the water to warmer water. If you have a heater bump it up to 75' degrees.

@stars_in_the_sky NO do not use a heater, gold fish are not tropical fish and do not need a heater, it will just make them more sick
