Pocket Reef: Cozy Aquarium

Pocket Reef is a cozy aquarium game about breeding fish and discovering what comes out.

Pair two fish and wait for the egg to hatch. Every fish carries a real genome — species, pattern, colour and face are inherited separately, so a pairing can surprise you. Thousands of distinct combinations exist, and the Aqua-dex tracks every one you have found, grouped by pattern so you can see exactly what is still missing.

Nothing in Pocket Reef punishes you. Fish never die. Timers finish while you are away, and a notification lets you know when an egg is ready. Put the game down for a week and your reef will be exactly as you left it.

WHAT YOU CAN DO

• Breed for traits — chase a specific colour or pattern, or pair at random and see what surfaces • Fill the Aqua-dex — every combination is catalogued, with completion shown per group • Complete the Order Board — neighbours request a fish by its traits each day. Hand one over for coins, with a streak bonus for keeping it up. A close match still pays, so there is always something you can fill • Collect sets — colours, patterns, fins and faces each form a checklist with rewards • Decorate your tanks — earn and place decorations, and choose a backdrop for each tank • Play without an account — no sign-up, no login, and your reef is ready the moment you open the app

Pocket Reef is free to play. It includes optional ads and optional in-app purchases; neither is required to see everything in the game.
