Build your aquarium.
Get to know who's in it.

This is Pip. (Say hi.)

Someone might come say hello.

WHY WE'RE MAKING IT

The fish are the point.

We're working to make the most intelligent pixel fish we can. Fish you get to know by how they act.

PERSONALITY

You'll know
this one.

66 possible traits, up to four per new fish. Eating, sleeping, exploring, playing: their personalities show up in what they do.

RELATIONSHIPS

They have
a social life.

Shared swims. Nose boops. Best friends, rivals and jealous streaks. Different species can become besties, too.

TERRITORY

That is
somebody's cave.

Territorial fish defend their space. Trusted friends get a little more leeway. The neighbour? Depends on the neighbour.

DECOR THAT MATTERS

They live in
what you build.

Plants, shelters and swimming room affect comfort and happiness. Different fish have different ideas about a nice home.

EVERYDAY FISH BUSINESS

A little more
to get to know.

Favourite foods, thought bubbles, daily and weekly wishes. Feed them, try their toys, and see what makes each fish happy.

ROOM TO DISCOVER

See who
turns up.

Breed fish with inherited traits and rare colours. Discover species abilities, and build across eight aquarium environments.

TWITCH IN DEVELOPMENT

Let chat
into the tank.

Feed the fish. Play with their toys. Give Relay questionable directions. You're still in charge.

  • Pilot Relay. Steer, head home, or dance.
  • Feed and play. Free commands use unlocked food and placed toys.
  • A little thank-you. Subs, resubs, gifts and qualifying Bits bring celebrations, without buying fish, currency or upgrades.
  • …Was that a shark? Optional Channel Points for food, toys, piloting and a harmless click-away shark.

Your permissions, toggles and cooldowns. Broadcasters and moderators can stop the action.

Live Twitch sign-in and rewards still need testing before this is ready for players.

DISCORD IN THE PLAYTEST

Currently:
fish.

Optional activity sharing shows your environment, fish count and what you're doing. Fish and tank names stay private.

Playtester help and feedback live here, too.

STEAM + MOBILE IN DEVELOPMENT

Same tank.
Different screen.

We're working towards cross-save between PC on Steam and mobile. Your fish would come with you.

The current playtest is Windows only. Steam, mobile and cross-save are in development, with no release date set.
