My neighbor had several fish that looked like the one in today’s jigsaw puzzles. They were beautiful. She had them for over fifteen years.
Once when we went to Bali for a vacation years ago, we stayed at a hotel that had stepping stones in a koi pond on one side of the hotel. You could buy a handful of food from a gumball style vending machine to feed the fish for about a dime.
I thought you might like this one.
Enjoy!
