About this game
Build the Ultimate Aquarium
Omniquarium is a relaxing idle aquarium game where you collect and grow over 100 unique species of fish, sea creatures, and aquatic life across 10 beautifully crafted tanks — from a peaceful Nano Freshwater bowl all the way down to the haunting depths of the Twilight Mesopelagic zone.
Hatch. Grow. Sell.
Buy egg packs from the shop, watch them sink to the tank floor, and crack open to reveal random species. Feed your fish to grow them from tiny hatchlings to full-grown adults, then sell them for profit or keep your favorites locked away in your collection. Every fish has its own swimming style, speed, and personality.
10 Unique Tanks

Over 100 Species
From common goldfish and clownfish to rare deep-sea creatures like the Vampire Squid, Oarfish, and Leafy Sea Dragon — every tank has its own ecosystem of species to discover and collect. Track your progress in the Fishpedia and work toward completing every tank.
Upgrade and Expand
Improve your food quality to grow fish faster, unlock new tanks as your collection grows, and earn passive income from your fully grown fish. Rare shiny variants with unique coloring can hatch from any egg pack — worth 100x their normal value.
A Game for Everyone
Whether you have 5 minutes or 5 hours, Omniquarium is designed to be picked up and put down at any pace. No timers. No energy systems. Just you, your fish, and the sound of the water.
