They have to eat every day
When we bought our home we noticed a pond in the back yard, and it was not real big. Someone built it to hold aquatic life and to be enjoyed on a hot day. There is even a small wading pool on one end, and a hot tub on the other end. In the middle they put the wildlife and water plants and they installed an automatic fish feeder for ponds behind the plants. They love it, and I do too or they would be really skinny if I had to do it. I can’t remember things in the house no less in the yard.
