Friends, rivals, and the occasional scuffle.
Fish build relationships, swim together, greet one another, and argue over territory. A confident explorer and a shy homebody won’t live the same way.

GET TO KNOW YOUR RESIDENTS
Fish with minds
of their own.
They decide when to explore, play, rest, or spend time with a neighbour. Hunger, health, personality, and what’s happening around them all affect what they do next.
Give them something to do.
Watch them pop bubbles, chase a wind-up submarine, swim through hoops, or play tug with a kelp ribbon. Some join in; others watch for a while or move on.
Personality changes the way they live.
66 possible traits affect appetite, sleep, confidence, sociability, and more. Discover rare colours and species abilities, then help a fish complete its lifetime dream to earn an extra trait.
01 / BUILD
A tank you’ve made your own.
Arrange plants, rocks, ruins, homes, and ornaments from a catalog of over 100 decorations. Move, rotate, resize, mirror, and layer them to create your layout.
Choose a tropical lagoon, frozen fjord, volcanic caldera, glowing grotto, or the midnight trench. Different backgrounds bring their own scenery and distant visitors.
02 / COLLECT & BREED
There’s always another fish to meet.
Discover 40 species, from familiar swimmers to legendary and mythic residents. Their abilities can help neighbours, uncover treasure, or even slow nearby fish’s ageing.
Breed compatible residents, hatch eggs, and discover inherited traits and rare colour variants. More species are being added as development continues.
03 / AQUARIUM TECH
Build a little help into the tank.
Set up filters, feeding towers, lights, and temperature regulators. Send a utility drone out to clean or hunt for treasure, and add an incubator when you’re ready to breed.
Placement matters: devices have their own coverage, and your fish’s preferences affect how comfortable they are around them.
04 / PROGRESS
Plenty to work towards.
Earn over 1,100 achievement milestones through care, collecting, breeding, toys, and discoveries. Work through your fish’s daily, weekly, and lifetime dreams.
Unlock new residents and scenery, collect rewards and trophy ornaments, and expand your aquarium as you go.
Still in development. More fish, features, and places to explore are on the way.
