No buds yet LuAnn, but I think his fins are starting to longer and more muscular.
Rocmon that fish does that all the time, the only thing I guess I do to incourage it is to sprinkle the fish pellets around everywhere in the pond. If I just throw the pellets in the open water that koi, because of his size and aggressive nature, will eat up the majority of pellets before all the other fish (and turtle) have a chance to get their fair share. Sprinkling the pellets all around the pond gives the others more of a chance to spread out and seek out all the small nooks and crannies looking for food, also I think it gives them more exercise.
