Monster Aquarium

Step into Monster Aquarium as Director of a deep-sea research oceanarium. Ancient biomes cracked open after the quake — start with one lagoon, a curious egg, and a laboratory waiting to expand.

Hatch, feed, and raise creatures through every growth stage from egg to alpha. Tune each reservoir with temperature, lighting, salinity, depth, plants, and current. Place décor, watch tank mood, and move inhabitants so neighbors stay compatible.

Build across six biomes — tropical lagoons, deep abyss, crystal caves, frozen seas, lava basins, and ancient temples. Fill the Monster Encyclopedia with species lore, favorite foods, and discovery XP as you study the living deep.

Run the Research Board for daily lab assignments that reward credits and codex progress. Unlock the Genetics Lab to attempt hybrid breeding with known recipes. Host visitors in the Guest Pulse hall — match exhibits to families, scientists, and tourists, collect tips, and grow aquarium popularity.

Upgrade your wings with incubators, feeders, tunnels, and more. Progress stays on your device — open the laboratory and expand the abyss at your pace.
