Oldest koi is around 25 years old, but pond is now 29 years old and we also
put 40 tiny baby Golden Orfe in several batches over the first two years and
we still have about a dozen of them (they are huge and it's not worth
putting any more koi in whilst they are there since the koi respond to the
adult orfe pheromones and now don't grow!!)


We have not added orfes. How did you learn about the pheromone
influence of orfes on koi?
