Everything About The The Latest App Auto Aquarium

Auto Aquarium is a cozy little auto-battler that lives in a fish tank.

Draft a team of fish, arrange them across three lanes, and watch them battle on their own — no
twitch reflexes, no timers, just calm, satisfying strategy you can dip into for a few minutes at a
time. Lost a round? No big deal. It's the kind of game you open to unwind.

🐟 BUILD YOUR SCHOOL
Buy fish from a rotating shop and drop three matching ones together to merge them into a bigger,
stronger fish. Mix three families — Schoolers, Predators, and Tanks — to trigger synergies, then
send your team in.

⚔️ AUTO-BATTLE, ZERO STRESS
Each round your tank faces a new opponent and fights automatically. Watch the chaos play out at
1×, 2×, or 4× speed, or skip straight to the result. Survive eight rounds for a "Clean Tank".

🎣 RELAX AND REPLAY
Every run is different — procedural opponents, unique combinations team-building, and a gentle
difficulty curve. Cozy Mode eases things up after a rough streak so it never feels punishing.

🐠 MAKE IT YOURS
Earn pearls just by playing and spend them on cosmetics: rich water backgrounds, color tints,
fish palettes, and decorations like seaweed, coral, and treasure chests. Save up rare golden
pearls for prestige looks.

✨ COZY BY DESIGN
- One-handed, pick-up-and-play sessions
- Soothing underwater visuals, music, and ambient bubbles
- No account, no sign-up — your tank lives on your device
- Optional, opt-in rewarded ads only (never forced)
- No in-app purchases

Dive in, build your tank, and relax.
