Make a little room in your day for life beneath the waves.
LumiAqua is a relaxing aquarium game where you feed fish, clean their home, and watch them grow at their own pace. Colorful underwater scenery, freely swimming fish, and gentle music create a peaceful place to take a break from your busy day.
Your first companion is a tiny clownfish. Tap an empty area of the aquarium to drop a piece of food and watch it slowly drift down through the water. Nearby fish swim over for a bite. When a fish is not completely full, feeding it earns you a heart. There is no limit to how often you can offer food, so take a moment to check on each fish and give it some care.
When the glass gets dirty, gently swipe across the screen to clean it. Wipe away the haze and algae to reveal the underwater view and restore cleanliness. Tap to feed, swipe to clean: looking after your aquarium is simple and hands-on.
Fullness and cleanliness help your fish grow. The higher both are, the faster growth progresses. If either reaches zero, growth pauses. Each fish starts at 15 mm and can grow to a maximum of 45 mm with daily care. Its visible size grows along with its recorded length, giving you a little reminder of the time you have spent together.
Tap a fish to see its length, fullness, hearts earned, and other details. Use the pencil icon to give it a name of your own. A familiar name makes every visit feel more personal. Get to know each fish as you watch it swim and grow.
Spend the hearts you collect in the shop to welcome new companions. Your aquarium can hold up to 10 fish. Choose who to bring home next and gradually build a lively underwater world at your own pace.
Your fish can continue growing while the app is closed, depending on their fullness and the aquarium's cleanliness. When you return, you can see how much they have grown while you were away. Progress is saved automatically, so you can pick up where you left off.
An interactive tutorial helps you learn by doing, from feeding and cleaning to checking on your fish. Switch between English and Japanese in Settings. No account registration is required.
Give your fish a little care, then sit back and enjoy the view.
Bring a small piece of the ocean into your everyday life with LumiAqua.
