Why are my goldfish fins turning yellow?

Why are my goldfish turning black?

  • I went and bought some simple goldfish that were sold as feeders from petco a couple weeks ago and when i got them they started getting bacterial infections... I treated them with aquarium salt and they did great and are now healed completely but no i have another problem, they are starting to turn black!.. black patches keep showing up more and more almost if they were going through a color change there is only 1 outta 4 that is not doing this and it might just be because he is goldish black in the first place idk... i need some help...they aren't acting sick at-all they are spunky and are happier then when i got them but they just keep turning black.. first on the fins then now two have it on there foreheads..

Test your water - black marks are generally a sign of ammonia, likely with extremely messy Goldfish. Ammonia is toxic, the black is ammonia burns, it will aggravate them, it may make them seem "spunky" when in fact they're panicking! They may begin to gasp at the surface as ammonia basically dissolves their gill tissue, ultimately they suffocate to death. What is your set up? Common Goldfish are fast growing, very messy fish. They need large, over-filtered (canister filtered), fully cycled tanks, or a very large mature pond. They are quite the opposite of simple to keep! Very expensive to keep properly and live twice as long as dog or cat.
