Fishlets is a cute, cozy fish-collecting aquarium game!
Care for adorable pixel fish and design charming aquatic environments for your pets to call home. Collect rare fish and color variants as you relax and nurture your underwater friends. Feed your fish, manage their happiness levels, keep your tanks clean, and fight off invaders who threaten to upset the tranquility. Progress through the game's Adventure mode to unlock fish, critters, and decoration items, then dive into the virtual tanks mode for a more chill and relaxing experience.
Try out the two game modes to see which one you enjoy most. Adventure mode offers active play and by completing levels, you'll unlock fish, critters, and decoration objects to add to your virtual tanks. Idle mode is more of a chill, casual game mode where you can sit back, relax, and collect rare fish and their many color variants.
Visit the shops and browse the diverse selection of fish that you can add to your tanks! Every fish has a chance to spawn color variants that vary in rarity, along with ultra rare "unique" variants that look much different from their typical counterparts. Collect them all, or just your favorite ones!
The fish selection isn't the only impressive thing. Visit the Critter shop to add snails, shrimp, and even axolotls to your tanks. Stop by the Decoration shop and decide whether the driftwood or pineapple house would make a better centerpiece in your tank. Don't forget to visit the Plant shop to add some flowy greenery to your pets' homes.
Once you have your fish tanks just how you want them, let the game run on your second monitor while you study or sleep and watch your fish idle, swim, and school together. Every fish species has its own hand-drawn swimming animations and smooth movement system. The sound design has been carefully crafted to sound relaxing and peaceful, as any fish tank should be!
