I know that sounds crazy since it's December but we had a really warm Fall here in CA and I think the fish got confused. We are guessing it is about 3-4 months age and about 2" long. It seems to be a standard koi with the "ghost" markings on the head and metallic on head with orange and black spots on the body/tail. It must have been fertilized in August or September, kinda weird! If pic attached correctly you can see him :luxlove:
