Hello,
I noticed today that one of my younger Koi (Gary) had something on its tail/caudal fin. The rest of the body looks nice and healthy, and is eating well. I decided to net it to take a closer look. It appears to be a bit of loose skin or some kind of tissue. I am having trouble finding similar images (most I've found are much more dramatic, and round). Thank you for any help you can provide!
