New to Aquarium Quest? This guide walks you through everything you need to know — picking a biome, placing decorations, harvesting resources, managing energy, and growing your tank into a full farming operation. Use the menu on the left to jump around.
Getting Started
01 Choose your first tank biome
Start by picking your first bowl biome — either Freshwater or Saltwater. Fish can only live in their matching biome.
Brackish fish are special: they're compatible with both Freshwater and Saltwater tanks, which makes them flexible early picks.
💡
Your tank has limits for fish slots, decoration slots, and stored resources. You can increase all of these from the Upgrade tab.
02 Place decorations — fish need them to farm
Fish don't generate resources on their own. They need decorations placed in the tank to harvest from. Each decoration produces specific resource types:
Plant
Creature
Essence
Mineral
Treasure
Plant
Creature
Essence
Mineral
Treasure
⚠️
Match your fish to your decorations. Every fish can only harvest certain resource types. If a fish can't harvest a resource type produced by a decoration, that resource simply won't be generated. Always check the fish's harvest types before placing.
Harvesting & Energy
03 How harvesting cycles work
Harvesting runs in cycles. Each cycle consumes energy — roughly 15 energy at the start of the game. You can upgrade the cycle duration from the Upgrade tab to make each cycle more efficient over time.
Energy regenerates passively at 1 per minute. It's also spent on crafting, cooking meals, and hatching eggs, so managing it carefully is key to efficient progression.

✨
Free full energy restore: visit Explore → Seabed Temple to fully restore your energy. There's a cooldown after each restore, so use it when you're fully out.
Resources, Crafting & Cooking
04 What to do with resources
Resources gathered from harvesting can be used in several ways:
🍳 Cook meals — Restores energy, which keeps your harvesting going. Prioritise this early to maintain a steady loop.
⚒️ Craft materials — Required for upgrading your tank capacity (fish slots, decoration slots, resource storage limits). Materials can also be used to upgrade the tank directly.
🔄 Trade with NPCs — Exchange resources or fish for $Coral, the premium currency. NPC trades refresh regularly — resource trades roughly every hour, fish trades every few hours.

Currency & Fish
05 Bubbles & $Coral
Bubbles are the main in-game currency, generated passively by all fish. Most crafting recipes cost Bubbles. Bubbles are off-chain — they exist only within the game.
$Coral is the premium currency. You can earn it by levelling up or trading resources and fish with NPCs. Use Coral to obtain better fish, decorations, and other upgrades.

06 Eggs & getting new fish
Eggs can be obtained from the shop or as levelling rewards. Hatching an egg costs Bubbles + Coral and takes time — anywhere from minutes for a Common Egg to 2.5 days for a Mysterious Egg.
Each egg has its own rarity distribution: Common Eggs always hatch a common fish, Suspicious Eggs mostly hatch rares, Dubious Eggs usually hatch epics, and Mysterious Eggs hatch epic or legendary fish. Higher rarity fish generally have better Harvest Power and stats.

Full hatch chances, costs, and shop prices are on the Shop page.
07 The shop & feeding fish
Beyond eggs and decorations, the in-game shop sells fish food. Foods restore Hunger and also boost Health, Mood, and Growth — keep your fish well-fed and they'll harvest more efficiently.
Foods have diet types (omnivore, carnivore, herbivore) and a per-day purchase limit per shop slot. Cheap options like Fish Flakes use Bubbles; high-end foods like Corn and Ocean Hunter Mix cost Coral but give much bigger boosts.

Fish Passives
08 Passive abilities
Many fish come with a passive ability — a built-in bonus that is always active as long as the fish is in your tank. You don't need to trigger them manually.
Passives vary widely. Some boost your own fish — increasing harvest power, reducing energy cost per cycle, or speeding up crafting. Others are combat-focused, affecting battle stats like attack or defence. A few passives interact with the whole tank, buffing every fish inside rather than just the one carrying the passive.

You can see a fish's passive on the Fish Database page — hover the purple tag on any fish to read the full description. Building a team with complementary passives can significantly improve your farming efficiency.
09 Trinkets — pouches, tools & tablets
Trinkets are craftable accessories that boost your tank in different ways. They come in three families:
👜 Pouches — Increase storage caps for a specific resource type (Bubble, Creature, Plant, Mineral, Treasure, Essence). Available in Small (Lv 5), Medium (Lv 10), and Large (Lv 15) sizes.
🔧 Tools — Pickaxes, Hooks, Shears, and Looking Glasses in Copper (Lv 5), Iron (Lv 10), and Steel (Lv 15) tiers. Each tool boosts a specific harvest type.
💊 Tablets — Fizzy, Bubbling, and Effervescent tablets give consumable buffs. Effervescent uses a Rainbow Fragment so save them for late-game.

Progression
10 Expanding to multiple bowls
As you progress, you'll unlock additional bowls. Multiple tanks let you specialise — dedicate one to creatures, another to plants, another to essences — so you can farm exactly what you need without compromises.
Eventually you'll farm essences and craft higher-tier materials like rainbow items, which are the late-game progression milestones.

🌀
Essences require the right combination of biome, decoration rarity, and an essence fish in the tank. Check the Essence Guide when you get there.
11 Efficiency summary
To progress efficiently, keep these four things in mind at all times:
🐟 Match fish harvest types with the resources your decorations produce — mismatches mean wasted decoration slots.
⚡ Manage energy carefully — cook meals regularly, use the Seabed Temple restore on cooldown, and don't burn energy on low-value actions.
🏗️ Upgrade tank capacity when possible — more fish and decoration slots means more resources per cycle.
🔄 Trade excess resources for Coral — use Coral to obtain better fish and decorations that accelerate your loop.
