Ok, thanks for the update, that high elevation may make a difference and the experts (of which I'm not one) may be able to help in that aspect.
I remembered staying in an old hotel right in the middle of the city where we could see an old church to our left on the square from the balcony. They talked about everything being built on an old lake bed and that the church (large and all built of stone) had sunken something like 4 feet over the many years. Mexico City being built on an old lake bed (Azetc's I believe?) I made the incorrect assumption the elevation was low. But it is in fact pretty high. Plus you are looking down from the pond so the pond I assume is a fair amount higher?
I'm at a little under 1000 feet above sea level so have no experience with fish at that elevation. Interesting pond you are working with. Keep us posted.
