Novice raising koi urgently needs your help thank you

　　
Dear fish friends, everyone, this is my first time fish farming, professional knowledge is very lacking, there are many questions I would like to ask everyone, here for your help!This tank fish is the second wave of fish I raised. The first wave raised six small goldfish, but the sand we bought faded, which may have a great impact on the fish. The six small goldfish went to heaven one after another.My husband and I re-turned the tank, washed the tank, basked, and brushed the stones. The water basked for half a month. Then I bought the fish the day before yesterday. It was six koi.I learned on the Internet that after the koi was bought back, I should let him adapt to this tank. I cant feed him for a week, but I am particularly worried about starving them, and I want everyone to give me some suggestions

The fish pond has become smaller. Yuyou said: the grass gold is super resistant, and it should be no problem to put stones. Feed less and keep the water quality.
