CozyFish: Idle Aquarium

Welcome to your own cozy aquarium! CozyFish is a relaxing idle fish game where you breed fish, watch them grow and build the fish tank of your dreams.

Release tiny fry and watch them grow into adults, from a little guppy to a giant whale shark. Every grown fish earns coins. Sell fish, open new packs and discover rare species. The eldest fish of each species becomes a king and wears a crown.

🐠 BREED AND COLLECT FISH
• Hundreds of fish species, from common goldfish to legendary deep sea creatures
• Open fish packs and find rare, epic and legendary fish
• Raise a crowned king of every species
• Hang your best fish on a wooden trophy wall

🏝️ DECORATE YOUR FISH TANK
• Sunken shipwrecks, castles, pagodas and the ruins of Atlantis
• Fish swim around your decor, hide behind it and nap near the sand
• Many waters, sea floors and weathers: sunsets, snow, rain and northern lights

💰 IDLE TYCOON THAT PLAYS ITSELF
• Your aquarium earns coins even when you are offline
• Grow your fish farm, unlock new packs and build a bigger collection
• Watch out for predators and keep your peaceful fish safe

🎵 A CALM PLACE TO RELAX
• A record player with a collection of cozy vinyl music
• Soft underwater sounds and gentle animations
• No rush, no stress, play at your own pace

Fish in CozyFish have their own lives. They greet each other, chase food, hide from predators and rest at the bottom of the tank. Every aquarium you build feels alive.

Drop in for a couple of minutes, feed your fish, collect coins and relax. If you love aquarium games, fish tank simulators, idle tycoon games and cozy collection games, CozyFish is made for you.
