What s wrong with my goldfish? He has black spots?
I have two goldfish, one orange and one yellow. They have been living in the aquarium for 2 months now, but suddenly i noticed some black spots appearing on the yellow one. It's strange though the orange one has none. I changed the water, the filter , food and all stuff needed, but it's getting worse. The orange one seems to be normal.
the behaviour of the fish didn't change, just the colour of the skin.

Black is down to Ammonia so the black is the healing part Ammonia has been burning your fish alive .
2 Fancy Goldfish need to be in 30-40 gallons with Double filtration and a cycled tank .
2 Common Goldfish can start in a 55 gallon but will then need a 100 gallon then 150 gallons plus .With double filtration and a cycled tank .

maximum probable that is from an ammonia surge, fairly if the tank is newly set up. Black spots displaying up is a demonstration of ammonia burns, and the black is definitely the therapeutic area. The spots could be flat on the fish as nicely. i could recommend checking your water high quality, make constructive ammonia and nitrites are at 0 ppm,nitrates under 20 ppm. there is likewise a parasite which could happen as small black spots on a fish, i believe they're raised as nicely. yet, this is plenty greater probable to happen in pond form of fish, because of the fact the existence span of the parasite is somewhat complicated, concerning birds and snails, or perhaps then it is not that undemanding.
