Buy My Cozy Aquarium PC key

My Cozy Aquarium is an idle game about caring for fish and building a collection across themed aquariums. You feed and raise fish, decorate tanks and maintain their living conditions, then sell matured fish to earn coins and expand your underwater spaces.

Aquariums and fish

Begin with one of four aquariums and unlock the other three over time. Each aquarium has its own theme, water environment and fish to discover. The aquariums are Emerald Ripple, Coralspire Reef, Frozen, Abyss and Magic Cove. Their fish packages are inspired by real-life fish with a magical twist, and the game features over 320 fish species to collect.

You can buy surprise packs containing fish companions and nurture them from tiny swimmers into adults. Relaxing mini-games let you care for them as they grow.

Caring for your fish

Keep fish healthy by feeding them, maintaining the water temperature, cleaning air filters and scrubbing the aquarium walls. You can also upgrade fish food and add colorful decorations to customize your tanks.
