Tanks that work like wet puzzles
You design, decorate and populate each tank from almost 100 marine species, each with its own care needs around water quality, temperature, food and tankmates. Keeping one species per tank wastes space and staff time, so you slot compatible fish, crustaceans, corals and others together to make every tank pull its weight. You place filters, chillers, heaters and pumps, and decide between a central equipment hub or spread-out zones.
Staff, research and the bottom line
You hire staff for skill and future potential, then train generalists or focused experts to feed animals, fix equipment and run talks. Guest visits earn points you assign to new livestock and equipment, working up toward prestigious animals.
Campaign school, then your own aquarium
The 10-level campaign teaches designing and managing step by step, with each level setting its own conditions and objectives. Then sandbox mode opens up with custom settings and a random challenge generator for near-endless building. Guests need food, drinks, seating and toilets, and you route them past the gift shop on the way out. Plan staff talks by subject, time and frequency to earn extra points.
What else should you know?
Can you theme and decorate your aquarium?
Yes. There is a full theming and decoration system with paint, decorations, doors, gates, food and drink dispensers and balloon stands, plus over 100 placeable objects, so you can shape how each hall and tank looks for guests.
How do staff talks work?
Well-placed talks bring in extra points on top of normal guest visits, which helps you unlock new livestock and equipment faster.
Does it support mods?
Yes, it is moddable with Workshop support. Mods add more species and single-tile decorations, which is useful if you finish the campaign and want fresh livestock combinations in sandbox mode.
