My GoldFish started changing colors?

Question

It of course started out that orangy color and now it's starting to get black/brown spots all over it. Are they supposed to do so or is there something wrong with our tank?

Answer 1

This is perfectly natural. My chocolate fan tails (which I loved their copper color) turned silver white in the outside pond. Lighting on gold fish, as well as breeding plays a large roll in color (especially in their first two years). If gold fish are kept in a deep pond where very little ambient daylight reach, they will revert to a white or light color.
Select breeding makes different colors possiable. Since all gold fish are of the same "species" breeding especially in an outside pond can lead to many varieties of color. Some gold fish, like the chocolates are bread strickly for color. comets and shabunkins are also bread this way. Tail types etc. However, diet light and size can change these colors and the fish can resort back to the color of one or more of the parents.

The goldfish, Carassius auratus, was one of the earliest fish to be domesticated, and is still one of the most commonly kept aquarium fish. A relatively small member of the carp family (which also includes the koi carp and the crucian carp), the goldfish is a domesticated version of a dark-gray/olive/brown carp native to east Asia (first domesticated in China) that was introduced to Europe in the late 17th century. The mutation that gave rise to the goldfish is also known from other cyprinid species, such as common carp and tench.

To make these hearty pond fish more appealing to the eye color breeding was also introduced in the late 17th century.

HOWEVER:

Examine your fish carefully. Gold fish are prone to Melanophore Migration It starts often with a paling of the skin followed by black patches on body, usually on back or sides of fish.

There is also black spot disease
Shows up as black spots or patches. This is a prasitic disease
, it is possible to reduce the incidence of the parasite by removing or reducing the intermediate hosts such as snails. This will disrupt the life cycle of this parasite. Copper Sulfate (CuSO4) applied to correct this disease. If you have snails remove them before treating the tank. Copper sulfate can kill snails.

Just keep an eye on your fish for the next couple of days. Gold fish usually don't turn black, however if the goldfish was raised or hatched in a pond with shubunkins or comets, this is possiable since both are often black spotted.

Answer 2

Goldfish can bypass by countless shade variations of their lives. i've got faith the colour variations are genetically controlled, nonetheless i might wager environmental components might have some result. I in basic terms can’t make it easier to be attentive to what result. If the fish seems in any different case healthful, then it relatively is in all probability a classic incidence for that fish.

Answer 3

That's not unusual at all. It's very common for goldfish to change color as they age. No one can predict for sure what colors will be involved, when they will change, how much they will change etc. Only time will tell.

No worries, just have fun betting on how much he will change and enjoy the cool thing tha's going on.
