Aquarium Haven 3D: Fish Tank

Real-looking tropical fish, goldfish and a coral reef glide through a 3D aquarium in your hand. Nothing to keep alive and no timers to chase: just a quiet tank to look at whenever you want a calm moment. Start free with the Coral Reef tank and 6 marine fish. One purchase unlocks everything. No ads. No subscription. THREE AQUARIUMS, 50 SPECIES - Coral Reef: clownfish, blue tang, yellow tang, royal gramma and more among corals and live rock - Planted Tropical: schools of neon tetras, discus, angelfish, guppies and bettas over green plants - Goldfish & Medaka: ryukin, oranda, ranchu, medaka and a small koi Each fish is a detailed 3D model that swims in schools, turns and drifts at its own pace. A TANK THAT FOLLOWS YOUR DAY - The light follows the time of day: bright mornings, warm evenings and soft moonlight at night - After dark, night creatures come out: a moray eel, a cleaner shrimp, glowing moon jellyfish, flashlight fish and an octopus - Gentle background music with the sound of water and bubbles (each can be turned off) MAKE IT YOURS - Plant corals on the sand and scatter food to watch the fish gather - Select a coral or rock to move it along the bottom, delete a coral you planted, or undo your last change - Hide the Glass (Underwater View) in Settings removes the tank frame, so you look out as if you were in the sea - Tap any fish to see its name and a short guide (Field Guide) - Tilt your phone and the water sways - Viewing mode hides every button so only the aquarium remains - A small clock on the tank (on by default, off in Settings) - Take photos of your tank and use one as your wallpaper - Home Screen and StandBy widgets show your aquarium ON A FOLDABLE IPHONE On iPhone Duo, fold it halfway: the top screen shows the aquarium from the front, and the bottom screen shows the reef from above, where you plant corals and feed. Open it and the tank light comes on. Turn it sideways for a desk aquarium with a clock. Close it and a small window on the outside screen keeps a favorite fish company. HOW TO ENJOY 1.
