Hi there. Cyclops is our one-eyed koi of about 15 years. He lost an eye early in life and has always had trouble eating because of a lack of depth perception. We've always rooted for him and tried to favor him when feeding. Regardless he has grown slower than the others and has always been on the thin side. He has about ten other koi/goldfish in the 2000 gallon-ish pond ranging in size from 6 to 15 inches. About 5 days ago I noticed the output from the bio filter decreased and checked the intake which is similar to a pool skimmer. Poor Cyclops was stuck inside. I'm guessing he may have been in there for a couple of weeks but am not really sure. I took him out and noticed that he seemed particularly emaciated, seems to have a bend in his spine and could not maintain equilibrium. I've been trying to hand feed him but he seems to regurgitate most of what I give him. I took a short video of his behavior with my phone but I am not having much luck making it small enough to upload. I did upload to Youtube and hope folks will be OK viewing there. The link is:

I am not too hopeful but am already surprised that he has survived for almost a week after his ordeal in the skimmer. Thanks much for any advice!
