AquaCozy: A Tiny Pixel Aquarium on Your Desk
AquaCozy is a calm pixel-art aquarium built for a minute or two at a time. Feed your fish, keep the glass clean, and watch them grow, pair up and hatch fry you've never seen before. The tank waits for you when you're busy.
Breed fish nobody else has
- 72 species to collect, 44 of them hybrids you breed yourself across three generations
- Real genetics: every fish carries eight genes, fry inherit from both parents, and mutations turn up now and then
- About one fry in a hundred hatches shiny
- Fill your Fishdex by working out the hybrid recipes
- On a full moon night, a rare visitor may drift in
Decorate a tank that feels like yours
- 48 tank decorations, 4 substrates and 11 lights, including a UV blacklight that makes some fish glow
- 21 wall and desk pieces to decorate the room around the tank
- Four tank sizes, from Desktop Bowl to Show Tank
- Landscape mode fills the screen with nothing but fish
- Room themes from a quiet desk to Neon Nights
- Photo mode with a shareable card carrying your keeper name
Gentle care, real stakes
Feed, scrub algae with a sponge and keep the water clear. Set your sleep hours and the tank rests at night, so sleeping never costs you anything. A neglected fish can be lost, but only after days of clear warnings, and a free Second Chance brings it back for a whole day afterwards. Remember the ones who are gone in the Reef of Memories.
Something new every visit
- Daily chest, care streaks with streak freezes, milestone rewards
- Reef Pass seasons: 40 tiers every 28 days
- Google Play Games achievements and leaderboards
- Lo-fi radio stations and Reef FM
