Telion, if you want to get plants going on the bottom of your pond. I would suggest adding the plants soon and hold off on adding any large koi. Although, depending on how much you feed your small koi they could be large in short order.
This gives the plants a chance to take hold and get going. I have a lot of plants growing bare root, in pots or in pea gravel beds in the pond. I found the trick was to let them get well established before adding large koi. The koi still dig around in the root system, but they are so well established they never really do any damage. This works with marginals and lilies, submerged plants like anacharis and vallisneria, don’t bother that stuff is like all you can eat salad bar. My koi do leave hornwort alone, as far as submerged plants go.
Now I should also say my largest koi is about 18”, the herons seem to pick them off eventually before they get much bigger. Just lost three koi this past week while I was away. Fortunately, they keep reproducing, so the little guys eventually get big and the cycle continues.
