Aquarium Simulator Pro

Available in English and Turkish. The game picks your device language on first launch, and you can switch at any time in Settings. Aquarium Simulator is about what it actually takes to set up and keep a real aquarium. The fish are not decoration — they react to water chemistry, temperature, their tank mates and how often you show up. THE TANK STARTS EMPTY You choose the dimensions, lay the substrate, fit a filter and heater, and fill it. Then you wait: adding fish before the bacterial colony is established is a disaster here, exactly as it is in real life. A REAL NITROGEN CYCLE Ammonia, nitrite and nitrate are simulated separately. Bacteria grow or die back with temperature and oxygen. pH, KH and GH are coupled; a catappa leaf genuinely acidifies and tints the water. Cycle the tank patiently and the game rewards you for it. THE FISH ARE ALIVE 17 species — guppy, betta, neon tetra, discus, angelfish, goldfish (common, oranda, telescope), molly, ram cichlid, Malawi cichlid, kuhli loach, pygmy corydoras, oscar, bristlenose pleco, nerite snail, Neocaridina shrimp. Each has its own temperature range, minimum volume, shoal size and temperament. Kuhli loaches hide by day and comb the substrate at night. Two male bettas will fight. A lone neon becomes stressed. Fish grow, go hungry, fall ill, and die under bad care. AN AQUARIUM YOU CAN TOUCH Tap a fish and it gives you a little greeting hop. Tap open water and a ripple spreads while a few curious fish swim over to look. Pinch to zoom in and watch a single fish up close. YOUR TANK EARNS FOR YOU Healthy fish leave small amounts of gold over time; tap the coin above a fish to collect it. Fry have to grow up first — a fish that has grown drops more. Heaters and filters can be upgraded in the shop, and the old one sold back. YOU MAKE THE DIAGNOSIS Ich, columnaris or velvet? You read the symptoms and choose the treatment. Every medication carries a real trade-off: raising temperature lowers oxygen, antibiotics kill your filter bacteria, copper is toxic to invertebrates. A wrong diagnosis kills the fish faster. MAINTENANCE NEVER ENDS Two feedings a day at most. Gravel vacuuming and water changes. Scrubbing algae off the glass. Filters foul up, plants consume nitrate, floating plants cut the light. BREEDING Get the conditions right and livebearers will breed. Fry grow quickly and inherit their parents' colour line. But the tank imposes its own limit: fry do not survive in an overstocked aquarium. COLLECT AND PROGRESS Every species and colour variant has a collection card, and completing one means keeping that fish HEALTHY over time. Achievements, mini-games and maintenance chores earn money for new species, decor and bigger tanks. Some variants are deliberately hard to reach. DESIGN IT · Build your own layout: driftwood, moss tree, java moss, Christmas moss, marimo moss ball, anubias, bacopa, catappa, floating plants. Plants can be placed at mid-water and near the surface, not only on the substrate. · The background colour is free to change — some fish look far better against black. · Time passes while the app is closed. You will not find the tank exactly as you left it. Contains ads. Optional in-app purchases; the whole game is playable without them.
