Why did my Goldfish change color from black to gold after five years ?

Question

It's about 2.5 inches long, and is a fancy goldfish.

Answer 1

The colour black is unstable genetically in goldfish and they will change colour. Stress can also cause this.

A 5 year old fancy goldfish should be 6"-8" long, if yours is 2.5" it's horrendously stunted and probably suffering.

Answer 2

Cant tell you why, but goldfish have some pretty weird genetic traights, and changing color at random seems to be one of them.

Most goldfish start out silver/grey as babies, and get their true colour later... maybe yours was just much later.

Anyway, it's not your care that caused the change, its a genetic thing. Maybe if more people could keep their goldfish alive for 5 years it might be more common.

But enjoy you new 'Gold' fish  :-)
