142 sea creatures and the new "Phantom Reef" premium gacha! Collect everything from rare reef fish to whales and grow your own pixel-art aquarium.
Welcome, aquarium director!
Aquariumulator is a cozy, pixel-art management sim where you build your very own aquarium from the ground up. Welcome marine favorites — from clownfish and dolphins to orcas and the mighty whale shark — display them in your tanks, and draw in crowds of visitors. Raise your creatures, manage water quality and temperature, and use the changing seasons to your advantage as you grow the greatest aquarium in the world.
■ Raise Marine Life
Creatures earn XP and level up while on display. They learn skills, perform tricks, and steadily boost each tank's appeal. Nurture a cast of charming sea animals, each with its own personality.
■ Run Your Aquarium
Tanks work on a rental contract: pay an upfront fee, then juggle the daily rent as you expand. Choose from basic tanks, coral reefs, the deep sea, the open ocean, and more.
■ Manage Water & Temperature
Leave the water alone and it turns murky — keep it clean with regular water changes. Each creature also prefers a certain water temperature, so matching it to the season is the key to a thriving aquarium.
■ Enjoy the Seasons
Spring, summer, autumn, and winter cycle through. Different creatures and tanks shine each season, and visitor numbers and tips shift too. Watch for limited-time seasonal events!
■ Combos, Decor & Costumes
Pair compatible creatures and decorations to trigger combo bonuses! Decorate your tanks and dress your creatures in special costumes to bring out their full charm.
■ Missions & Ranking
Tackle a huge variety of missions and daily missions. Your aquarium climbs through ranks as your all-time visitor count grows, earning prize money at every rank-up and unlocking new tanks and creatures.
■ Gacha Collection
Spin the gacha to land surprise creatures and decorations, and fill out your collection.
With gentle pixel art and a bright, friendly look, Aquariumulator is easy to pick up and wonderfully easy to sink into. Start building your dream aquarium today!
