This past summer I caught two trout that were only 5"-6" long but they had a color pattern I have not seen before. The trout themselves had a black backs and the sides were grey rather then silver like most trout. Otherwise the trout looked like small rainbow trout. The trout were caught up in the Alpine Lake area in a small lake with a very dark bottom and old rock slides around most of the lake. I feel that the trout because of the dark bottom and lack of fallen trees or other places to hide well in, have adapted in this way to hide better from predators like hawks from above. If some one else knows otherwise or something else about this strange but pretty type of trout I would love to hear from you on it. I wish I had a photo of the fish but it was burried in my back pack at the time and I did not want the fish to be out of the water to long before they were released.
