❓ Frequently Asked Questions

Aquarium Quest is a cozy blockchain-based aquarium game on the Ronin Network. You collect and manage fish across three biomes — Freshwater, Saltwater, and Brackish — harvest resources from them, craft items, place decorations, and grow your aquarium. It combines idle gameplay with strategic tank-building and a play-to-earn economy.

Connect your Discord account and a Ronin wallet, then claim your starter tank. Place fish into a matching biome tank (Freshwater, Saltwater, or Brackish), start harvesting resources, craft materials, and place decorations to grow your aquarium. Use the Tools page to plan your tank setup.

Aquarium Quest is built on the Ronin Network, a fast and low-fee blockchain optimized for games. The Founders Pass NFT collection is available on both OpenSea and the Ronin Marketplace.

The three biomes are Freshwater, Saltwater, and Brackish. Each fish belongs to one biome. Placing a fish in its correct biome maximizes its Harvest Power. Brackish fish can adapt to both Freshwater and Saltwater tanks. The game currently has 25 Freshwater, 25 Saltwater, and 22 Brackish fish.

Rarity determines how powerful a fish is and how hard it is to obtain. The four tiers are Common → Rare → Epic → Legendary. Higher rarity fish generally have stronger battle stats, better harvest power, and more impactful passives. Currently the game has 21 Common, 19 Rare, 17 Epic, and 15 Legendary fish.

Harvest Power is how many resources a fish generates per harvest cycle. Capacity is how many tank slots that fish occupies — it ranges from 15 (small common fish) to 140 (large legendaries). Your tank has a total capacity limit, so higher-capacity fish leave less room for others. Use the Tank Builder to find the best balance of harvest power per capacity slot.

Every fish harvests one or more of five resource types: Creature (zooplankton, shrimp, shells etc.), Plant (kelp, seaweed, wood etc.), Mineral (limestone, gravel, ore etc.), Treasure (doubloons, diamonds, pearls etc.), and Essence (rare magical essences). Check each fish's harvest slots on the Fish page.

Passives are special traits that affect your tank or the fish itself during harvesting. For example, Schooling gives +15% Harvest Power per additional fish of the same species. Tranquil boosts mood of all tankmates by 2/tick. Apex Predator has a 33% chance to attack a random tankmate while harvesting. Most passives stack up to a limit — check the full list on the Fish page.

Yes. Passives like Predator, Apex Predator, Territorial, and Venomous can damage or debuff tankmates. To counter these, pair aggressive fish with ones that have Elusive (50% chance to ignore negative effects), Oblivious (immune to mood penalties), Keratin Shell (50% health penalty resistance), or Guardian (reduces health penalties for all tankmates by 15%).

Each fish has one or more battle roles: ⚔️ DPS (deals high damage), 🛡️ Tank (absorbs damage, protects the team), and 💚 Support (heals or buffs allies). Building a team with all three roles covered generally performs best in combat.

Hunger Delta shows how fast a fish's hunger decreases per tick. A higher value means the fish gets hungry faster and needs feeding more often. Fish with the Photosynthesis passive are special — their hunger cannot drop below 50%, making them much lower maintenance.

Decorations serve two purposes: they generate additional resources that your fish alone can't produce, and they affect your tank's Hygiene and Mood stats. Some decorations increase hygiene (🧼), some boost mood (😊), and some do both. Higher rarity decorations generate more resources and have stronger stat effects.

Match decorations to your fish team's harvest type and rarity. For example, if your tank is full of Legendary fish harvesting Creature resources, a Legendary decoration that generates Creature-type materials will yield the most output. Use the Tank Builder — it automatically picks the best-scoring decorations for your team. There are currently 32 decorations across all three biomes.

Hygiene and Mood are tank health stats. Low Hygiene can cause fish to get sick or generate fewer resources. Low Mood reduces fish productivity and can trigger negative effects. Decorations with positive Hygiene/Mood deltas help maintain a healthy tank. Fish with Slimy (+2 hygiene/tick) and Tranquil/Luminous/Cheerful passives also help.

Harvest resources from your fish and decorations, then go to the Craft menu. Select a recipe, make sure you have all the required ingredients, pay the Bubble and/or Coral cost, spend the energy, and wait for the craft timer. Craft times range from 3 minutes to several hours depending on the recipe tier. There are currently 28 recipes across Freshwater, Saltwater, and Brackish biomes.

Energy is consumed by crafting and other actions. It regenerates passively over time. You can also restore it by eating cooked meals, or visit the Seabed Temple to fully restore your energy every 12 hours. Fish with the Electrified passive have a 5% chance to refund 1 energy per harvest, and Photosynthesis fish have a 5% chance to restore 15 energy per harvest.

Bubbles and Coral are the two in-game currencies used for crafting costs, buying decorations, and other transactions. Some recipes require Bubbles only, others need Coral, and some need both. The Auspicious passive gives a 5% chance to receive 10% more Bubbles per harvest.

Recipes are grouped into tiers (Utility, Basic Organic, Basic Material, Hybrid Material etc.) and require a minimum player level to unlock. Level 1 recipes are available from the start. Higher-level recipes give more XP and produce more valuable outputs. Check the full recipe list on the Crafting page.

The Tank Builder is a wiki tool that helps you plan the most efficient aquarium setup. Enter your fish and decoration capacity limits, optionally pre-select fish you already own, and it generates five optimized build suggestions: Balanced, Max Efficiency, Full Coverage, Passive Synergy, and Essence Farm. Each build is scored and explained.

Harvest Efficiency is your total Harvest Power divided by the total Capacity used. A higher efficiency means you're getting more resources per tank slot. The Tank Builder's Max Efficiency build prioritizes this — great for players who want maximum output from a smaller tank.

Essences are rare resources harvested only by specific fish. There are 12 essence types across Spring, Tidal, and Marine categories — in Common, Rare, Epic, and Legendary grades. Each essence requires the right combination of biome, decoration rarity, and an essence-capable fish in your tank. Check the Essence Guide for the full breakdown of which fish produce which essences.
