I have a fish which is changing colour?

Question

Ive had a fish tank now for 2 years and i know goldfish change colour,but i have got 2 black moors and 1 of them is turning orange is this normal.Ive had them for a year now and its the 1st time this has happened.

thanks copperhead,she looks exactly like that other fish

Answer 1

It can be normal. Black is one of the hardest colors to maintain in a goldfish, so if it had any amount of orange or broze color on it originally, it will most likely change to orange or yellow (or bicolor) over time. Some fish take the change all the way to white. (it most likely will stay the lighter color, not revert back)

Here's a link to a color change documented in photos: http://thegab.org/Articles/ColorChange.html

Answer 2

Copperhead is exactly right and the pictures are great. Goldfishes' color genetics are about the most unstable of just about any animal there is. But, having said that, a true, well-bred moor is the most stable goldfish there is and is just about as stable as any animal can and should be, and a true, well-bred moor should never vary from solid black. That's why saying "Black Moor" is, or should be, redundant. Because true moors are always black. So, if a "black moor" ever changes in its colorings, it is because it was not well-bred and was bred with a non-moor goldfish, thus bringing back in a variety of colors other than black.

Answer 3

Some female fish can change colour when they are in labour!
Its so the fry can identify them!
Its normally under their belly!
