Stocking tanks like a wet puzzle

You start with a few basic tanks and work up to sharks, corals, jellyfish, and almost 100 species in all. Each animal has its own care needs for water, food, and tankmates, so much of the game is finding combinations that live well together in the fewest tanks.

You group animals by food type or water quality, place filters, chillers, and heaters, and adjust until the whole room hums along. It is calm, methodical work, and watching a tricky mix settle feels earned.

Staff, research, and the bottom line

Guests bring in points as they enjoy your displays, and you spend those points to unlock new livestock and equipment. Money matters too: fussy eaters need costly food, big tanks cost plenty, and new hires add to the wage bill.

You choose staff for skill and potential, then train generalists or sharp specialists, schedule their talks by subject and time, and lay out pumps and equipment so keepers can reach everything. You set the pace, and the numbers tick upward while you plan the next display.

A bright aquarium to shape and stroll through

You decorate tanks, paint walls, add seating, food and drink stands, toilets, balloon stands, and a gift shop by the exit. The look is cute, colorful, and family friendly, with an isometric view that makes a full house of guests and busy keepers easy to read.

The 10-level campaign teaches the systems step by step with its own goals and conditions. Then sandbox mode opens up with custom settings and a random challenge generator, so you can keep building themed halls from tropics to cold water just for the pleasure of it.

Good to know before you build?

Do you run the whole aquarium yourself?

Yes. You design exhibits, choose livestock, hire and train staff, research equipment, handle money, and look after guests with seating, snacks, toilets, and a gift shop. Keepers feed animals and maintain tanks, but every layout and hiring choice is yours.

How do you unlock new fish and gear?

Guests earn you points as they view displays, and you assign those points to new animals and technology. It rewards placing popular, well-kept exhibits where visitors can easily find them, then spending the income on the next upgrade.

Can you play at your own pace?

Yes. There is no combat, and the campaign gives one clear goal per level without mid-level surprises. You can pause, rearrange tanks, retrain staff, and let points build while you decorate, which suits long, low-pressure sessions.

What happens if fish are unhappy?

Animals with the wrong water, food, or tankmates do poorly, so you move them, improve filtration or heating, or change the mix. The game gives you the care details for all 97 species, and learning good combinations is much of the fun.
