Send me also lay.... I'm always a sucker for good information.
After I read this post, one thing I never hear people mention is water condition/quality. Everyone seems to be focusing on the view, and how the koi get scare when people walk by....
Let me share my experience with you. I started my koi hobby with a FG tank (5ft x 2.5ft x 1.5ft). When I first started, just like any beginners, I overstocked my tank. Then I realized that the koi were very jumpy. They would dash whenever someone walked near them. When you threw in the food, some of them would just jump up and snap the food and run to hide. This had been going on for several months and became a vicious cycle. I had always tested my ammonia, nitrite, nitrate, ph, etc. and everything was ok.
Later on, I realized that everytime after I did partial water change (sometimes 50%), the fishes seem to be more energetic and they tend to swim up more and became more friendly. After that, I added more bio materials, added a TT, did more partial water change, things started to improve significantly. They were no longer shy and would sometimes cruise around on the surface.
Now that I have a new pond, the fish are like in heaven. Since the pond is exposed to 100% sunlight, they will hide in the day time, but will come cruising, waiting for food in the morning and night.
What I make out of this is the DOC (Dissolved Organic Compound) in the water or the dissolve oxygen level that makes the difference.
Instead of focusing on covering the tank with blanket, try to do some water change or relook at your filter system and see if it improves the situation. Also, take a look at the color of your fish, if they are happy, their color will be vibrant.
