About the game
Fantasy Aquarium is a relaxed simulation in which players raise a range of tiny fish, each with distinct traits, and build their own fantasy underwater world from the ground up. The game layers fantasy elements and open-ended aquarium design on top of traditional fish-keeping. MOON SCAPE developed the game, and Gamersky Games published it in 2024.
