He's been growing RAPIDLY since I unknowingly rescued him from the LFS's fancy goldfish tank. He was VERY thin (like a skinny comet) this spring, but the lil' piglet's filling out nicely I think. And his fins/tail... they just keep getting longer and longer. He didn't even have many dark gray coloring when I got him really, nothing more than a couple "freckles," but over the last month or so they've grown/darkened... & he's also developed a couple dark gray streaks of color on his tail, and one across his dorsal fin.
A BUTTERFLY?! omgoodness! It's a shame he's missing a pectoral fin.

I bet he's gonna be BEAUTIFUL someday... and even more of a shame that I can't keep him. *sniffle*
Another riddle I've been pondering: If he has most of the main spine of his missing pectoral fin, but is missing the rays, and even uses that spine to maneuver himself at times... In your koi-ly educated opinion...
Do you think it was a congenital defect? Or something that may have happened while he was very small? Like... he was the victim of a nipping, or... maybe an infection/finrot? *trying to find a clear photo of his nub*
Thanks for your input, Larkin!
