Answer 1

It might just be natural. I had a completely black goldfish, but a couple months later he started turning reddish. Now, its completely orange. It might be the food or maybe even some bacteria in the water.

Answer 2

Purple is not a color for goldfish.  If it's the ends of the fins it's probably ammonia burns.  A goldfish requires a minimum of a 20 gallon tank with excellent filtration.  If ammonia builds up in the tank/bowl it can burn the fins on the fish as well as the gills.

Answer 3

since your goldfish is indoors some do change in colors if you want put it in an outdoor pond in a week its colors will be back.

Answer 4

This could be happening for a couple different reasons.

A. Young goldfish change colours for the first year or two normally, and you have nothing to worry about.

B. Your goldfish has been through a stressful or traumatic experience recently, such as moving to a new tank or adding new tank mates and its fins are temporarily turning blackish.
