Newbie Question

Question
We have recently installed a pond in our back yard.  We did this with the intention of making it "the perfect" environment for fish.  We did a lot of research on the subject, learned everything we could and asked many people many questions before we put our fish in. We have encountered a few things however that we didn't expect. We have 3 Bangkok Koi and 6 goldfish.  One of the problems we are having is one of the koi eats all of the food before the others can get to it and I'm afraid that if I put more in, I will harm the "hungry" fish if it eats more of the food.  I have also read that we should only put in enough food that the fish will eat in 3-5 minutes.  How do I make sure that all of the fish are getting something to eat? I have been feeding the fish pellets and was told to put 5 pellets per fish in the water 4 times a day but the weather is still chilly and the fish are not real active.  I worry that too much food may not digest properly. All the the fish are relatively small.  The goldfish are 3 inches and the Koi are 5 inches long. Should I put more food in the water than suggested and just scoop out the remaining food after a few minutes? I have been feeding very little (about 2 pellets per fish) once day.  I live in Nova Scotia and the water is still fairly cool here, about 55 degrees. I have 6 water lettuce in the pond that I have seen all of the fish nibbling on. We were told that the fish will only eat this if they are hungry but have read that the Koi would eat it just because its there.  I would really appreciate any insight you can give on helping me make sure I am properly feeding these fish.

Answer
I believe the best solution to be feeding in two different spots at the same time.  Start at any random part of the pond.  The more aggressive fish, obviously being the best hunter, will surely find this feeding location.  Then, once it is preoccupied, feed the rest of the fish in a usual feeding spot.  You will most likely have to overfeed then remove the excess food, just to occupy the aggressive fish for long enough.  You may have to play around with your exact strategy to get the proper method.  Maybe even record a feeding journal for the first month.

On a side note, that very hungry fish may be more likely than normal to eat snacks out of your hand.
