Mystery fish
Please could anyone identify the fish shown at
http://www.geocities.com/renes_smither/mypage.html We recently moved to a house with a pond which has 60+ black fish in it. I would like to know what they are. I suspect they are goldfish without the gold colour but I am not sure. Renes |

Mystery fish
The picture loaded too small for me to make a judgement on what the fish is,
it could be a goldfish but the shape doesn't seem quite right. "Renes Smither" wrote in message ...

Steve,
If you download the picture by right clicking on it it can then be opened in MS Paint or whatever JPG editor you have on your PC. The real image is quite large and hi-res, and is 440KB in size. I just put the site up in geocitees as my news provider does not host the binaries groups. I would be very interested in your opinion. Regards, Renes "Steve in 236" wrote in message rthlink.net...

Regards, Renes Renes, I viewed the picture with MS paint and I'm changing my mind. You've run headlong into a wonderful lesson on natural selection. What you have are nice, plump "brassies". Brassies are the common goldfish (Carrasius auratus) that have been born with a more natural brass coloration. A millenia or two ago, almost all goldfish were that color. The Chinese started the aquarium hobby by hand selecting the few brightly colored fish out of their food ponds and raising them in ceramic pots. At one time someone introduced ornamental goldfish to the pond and they spawned, and genetics being what they are this led to a mix of colors in the offspring. Obviously, being a flaming orange color is not the best tactic in the natural world. Predators have picked off all of the brightly colored goldfish in the pond, leaving the better camoflaged ones. This could easily happen in one generation. |

Also we have a visiting heron who has probably been the evolutionary driving factor. All the best, Renes |
