About
Store description and overview from Steam.
Cozy Littlequarium is a relaxing game that sits at the bottom of your screen, fitting perfectly into your daily routine, whether you're working, studying, or having fun with other tasks. Have your own aquarium always available at the bottom of your screen. Take care of it at your own pace, no rush, no worries, and enjoy the company of your new little fish.
Purchase a wide variety of fish to populate your aquarium. From colorful tropical species to peaceful freshwater dwellers, you can add them all to your tank. But remember, they need your care! Feed them regularly and keep an eye out for any signs of illness—it's up to you to ensure they stay healthy and happy.
In Cozy Littlequarium, your aquarium is your personal masterpiece. Choose from a variety of decorations to create the perfect underwater world, from calming stones and plants to colorful corals and unique items. You can also change the floor texture to suit your style, and even adjust the color and opacity of the water to set the mood. Whether you want a peaceful, natural look or a vibrant, magical environment, the choice is yours—design your dream aquarium and make it truly yours!
Combine different fish to breed new and exciting species! As your fish reproduce, you’ll unlock a range of unique and rare breeds. Experiment with different pairings to discover and collect all the amazing species the game has to offer.
Collect every fish species in the game! In Cozy Littlequarium, your journey to discover and collect fish is tracked in an interactive Compendium. This vibrant collection features all the fish species you've encountered, organized by color and type. Each new discovery is added to your Compendium, creating a beautiful, colorful record of your aquatic adventures.
Whether you’re hunting for a specific fish or just enjoying the thrill of discovering new species, the Compendium will be your trusted guide and a rewarding reminder of your accomplishments.
