Fish Colors Change Before Our Eyes
A week or so ago, I noticed a pretty big goldie swimming around in the VF.
It was in the upper pond which tells me, it took a ride through the pump, so it must have been very small when it arrived. It's now about 4 inches long. Anyway, we rescued him/her yesterday as that part of the VF freezes solid every year. When we brought him in he was distinctly black colored, as he swam around in my SO's salad spinner. After letting the water warm a bit, I dumped him into the aquarium. I noticed however over a few hours he changed from distinctly black to a golden color. I don't know if he is a goldie, koi or koidlie as he seems to have features of all three. Either way, do goldies, koi or donkey koi/goldies change color over hours? BV. |

I can't say for sure about goldfish, but I've watched markings on many fish, including koi, appear out of nowhere. Black pigments seem to be particularly easy to turn on or off - though I'd normally expect the more pigmented form to be the less stressed (sick fish often look very washed out) but that seems to be the opposite of your case. -- derek |

Next day, when the lights come back on, he turns yellow again. Most likely a defensive adaptation. I've always believed that goldfish being black at birth and for a time afterward is a defensive adaptation. Many animals have this kind of adaptation. |

I have black goldie babes go gold, but I have never seen a fish change color in hours. I swear I am not imagining this. Anyway he/she/it is swimming around in the 55 gallon tank and the other fish seem to like he/she/it. BV. |

Just a thought and winter is yet to begin. |
