Update
It looks like the sick fish is doing better. He's returned to normal size, and is feeding and moving about in a fashion similar to the other fish in the pond. We've returned him to his home, and will keep a close eye on him, and everyone else until the water warms up and we're back to known conditions.
Thanks for all the help, so far. I'm learning, and I'll post pics in the appropriate section of the forum, soon.
