I went to the local fish store today to buy some blood worms and I stopped by their goldfish section. Usually they don't have anything that I'm interested in but today they had a tank with four comets in it. They said someone had brought them in from their pond about six weeks ago and that they were going to a big aquarium at a local furniture store (Gallery Furniture). I said "too bad because I would love to have a black comet like that". I had never seen one that color in person before. Well, he went back to double check and the manager said they were tired of waiting for the other folks to come pick them up and I could buy them if I wanted. So I feel very lucky to have got this black comet. It's about thirteen inches from tip to tip. It's not really black but sort of olive/blue/black/?.
Here's a pic from the tank at the store:

And here are a few more after he got to my house:
