Raise fish, breed rare ones, sell to the market. A cozy pixel fish tank.
Aquarium: Fish Business Empire is a cozy pixel art fish tank that slowly turns into a fish business. Feed your fish, keep the water clean, breed the rare ones and sell them on a market that moves while you are away. It is a calm game to check in on a few times a day, not one that asks for hours.
YOUR TANK
Start with a desk tank and a few guppies. Tap where the food should fall and watch the fish come for it. Every species has its own swim, its own size and its own place in the water, from the guppies near the surface to the bottom dwellers on the sand. Decorate with plants, rocks and ornaments, and keep the glass clean with a scrub.
COLLECT
There are 52 species to find, from neon tetras and bettas to koi, reef sharks and the giants of the open sea. Each fish is one of a kind, with its own rarity, gender, age and family tree. The Aquapedia keeps every species you have met.
BREED
Put a male and a female together and they court, spawn and raise babies. Some species give live young and some lay eggs, and hungry tankmates will eat them if you are not careful. Breed Rare, Epic and Legendary fish, and with patience, an Awakened one that thinks out loud.
RUN THE BUSINESS
Sell your fish on a market that works like a stock app. Prices move day by day, every species has a chart, and buyer orders ask for exactly the fish they want. Sell into a glut and the price drops, so timing matters. Spend what you earn on bigger tanks, better gear and more fish.
GROW
Move from the Cozy Desk to the Living Room and the Sun Room, and finally out to the Open Ocean, a real sea bay where whales surface to breathe. Your tablet runs the whole operation: the shop, the market, breeding, messages, music and your daily tasks.
TAKE IT EASY
Fish live in real time and age over weeks. An auto-feeder hopper keeps them fed while you are out, and the tank earns while you are away. Daily tasks and a seven-day streak give you something small to do each visit.
