How many fish do you have?
Inside my house I have one tank with three Fancy Goldfish and in my pond outdoors I have two 4ft long Sterlet Sturgeons, 2 Japanese Koi and about 50 normal goldfish.
I am slowly converting the koipond into a Fancy Goldfish pond. I have liked the look of a bald pond, but it became pretty boring. It had no plants and you could only see the Japanese koi. I have added some waterlillies last year and other aquatic plants. It looks much better now and more beautiful. I even added a small waterfall for extra oxygen.
In the next few months I will add a light under the waterfall so you can see it in the evening.
