Aquaidle
Aquaidle is a free-to-play, idle-based aquarium management game on Steam where you build, customize, and run up to 100 aquariums. Enjoy a relaxing experience as your fish generate income automatically, or engage actively by feeding them to boost profits. The game adapts to your playstyle—whether you prefer a laid-back idle mode or a more hands-on clicker approach. You can unlock new tanks, expand their size, and apply upgrades to maximize earnings. With over 2,400 unique fish species—including 160 base types, 5 variations each, and 3 size categories—discovery and collection are at the heart of the fun. Decorate and personalize each aquarium to reflect your style, from tranquil landscapes to vibrant coral reefs. Aquaidle also features Steam Inventory-based daily and weekly drops, letting you collect rare fish, decorations, and exclusive items just by playing regularly. Plus, a player-driven trading economy lets you buy, sell, or trade fish with others, making the experience dynamic and social. Aquaidle blends.
