In that case,
Here's Your Challenger:
SR-71 Blackbird (Yes, he's named after the famous Air Force jet.)
And these were taken with flash, since my awesomer and better camera is now broken. D:
But without flash, his dorsal fin is as green as is seen here, his tail color is blue like the metallic scales across his body, and his anal fin appears a darker red, almost black. His body seems black and shines blue only in the sunlight.
Also, he had a bit of fin rot on his tail. It's healing now, but the double-ray isn't obvious anymore. |D
