Build your dream aquarium
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Sell duplicates, automate with facilities, and track it all in the new Business Report. 155 sea creatures to collect in 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. Manage water quality and temperature, invest in facilities, and use the changing seasons to your advantage as you grow the greatest aquarium in the world.
■ Collect Marine Life
155 species to discover. Pull the gacha, place your creatures in tanks, and watch the crowds grow with each tank's appeal. Duplicates can be sold for a price based on their rarity, and filling in more of the catalog earns you collection rewards.
■ 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, a jellyfish hall, and more. Climb the ranks to lease even more tanks.
■ Build Facilities
Expand a tank to raise its creature and visitor capacity, install filters to slow water decay, and hire a keeper to handle water changes and refill feed for you — so you can spend more time simply watching the fish.
■ Manage Water & Temperature
Leave the water alone and it turns murky — keep it clean with regular water changes. Each tank also prefers a certain water temperature, so matching it to the season is the key to a thriving aquarium.
■ Read the Business Report
Today's income and expenses, recent trends, each tank's contribution, a satisfaction breakdown, and your progress toward the next rank — all in one place, so you can plan your next move.
■ Enjoy the Seasons
Spring, summer, autumn, and winter cycle through. Different creatures and tanks shine each season, and visitor numbers shift too. Watch for limited-time seasonal events!
■ Combos & Decorations
Pair compatible creatures and decorations to trigger combo bonuses! Decorate your tanks with over 110 decorations 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 visitors. Over 50 quirky visitor types are waiting to be discovered.
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!
