📌 Key Rules
💎 Deco rarity = essence rarity. Always. No exceptions. A rare deco always produces rare essence.
🐟 Fish rarity doesn't matter for essence tier. A common essence fish works the same as a legendary one for determining rarity.
⚡ Fish just needs essence in its harvest slots. Speed scales with Harvest Power as usual.
⚠️ Common fish + rare deco = rare essence but very slow. Higher Harvest Power fish matters more for rarer essence.
🏡 All decorations produce essence — what separates them is only biome and rarity.
🌀 No brackish tanks exist. Tidal essence is produced through brackish decos placed in freshwater or saltwater tanks.
⚗️ Quick Formula
Any rarity FW Deco → Spring
Any rarity SW Deco → Marine
Any rarity Brackish Deco → Tidal
Deco rarity tier directly sets the essence rarity tier. The tank biome sets the essence type (except Tidal which uses deco biome).
