My Koi is a pond simulation where you create and care for koi. You can keep up to 18 fish in each of three ponds, customize their scale patterns and colors, and give each fish a name.
Feed your fish and observe them swim toward food, grow over time, and change in happiness. Growth and milestones unlock additional fish slots and varieties; you can also track each fish and view it underwater.
Arrange each pond with rocks, plants, substrate, and water color. The time of day can change as you play, affecting the light and sounds, or you can set a fixed time and use ambient mode.
Players often describe My Koi as a peaceful, low-effort experience, appreciating the fish’s realistic movement and the calm atmosphere it creates. Some enjoy customizing koi and watching them grow, while others value it more as an aquarium-like backdrop than a game. Recurring requests include more pond decorations and activities such as breeding.
