📖 Beginner's Guide

Start by picking your first bowl biome — either Freshwater or Saltwater. Fish can only live in their matching biome tank. Brackish fish are special — they are compatible with both Freshwater and Saltwater tanks, making them flexible picks early on.

Fish don't generate resources on their own. They need decorations placed in the tank to harvest from. Each decoration produces specific resource types:

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.

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.

Bubbles are the main in-game currency, generated passively by all fish. Most crafting recipes cost Bubbles. Note that 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.

Eggs can be obtained from the shop or as levelling rewards. Hatching an egg costs energy and rewards you with a new fish of varying rarity.

Higher rarity fish generally have better Harvest Power and stats, improving your farming efficiency over time. Build towards rarer fish as you progress.

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.

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.

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.
