Reefkeeper: Aquarium Tycoon

A thriving habitat starts with small, thoughtful decisions. Reefkeeper is a calm aquarium management game: build habitats for seven groups of sea life, keep their water clean and warm enough, and make room for visitors to discover a world beneath the surface.

Every species group has its own ideal water temperature. Filtration, oxygen, food and cover decide how well each habitat thrives, and the residents' wellbeing earns science for your research. Set the feeding policy and the climate, price the tickets, study the species you care for, and look after the coastal dolphin and offshore whale reserves on the management map. Between days, rearrange anything.
