Fisch Deep Sea Expansion: New Zones, Fish & Gear

Deep Sea Expansion

Fisch's biggest update yet is here. The Deep Sea Expansion adds an entirely new biome below the existing ocean floor, three new fish rarities, and a deep-sea diving gear system.

The Abyssal Trench

A massive underwater trench has opened up south of the main island. To access it, you need the new Diving Bell item from the Dock Shop (costs 5,000 Coins). The trench is split into three depth zones, each with unique fish and increasing difficulty:

• Twilight Zone (200-500m) - Bioluminescent fish, moderate pressure
• Midnight Zone (500-1000m) - Rare anglerfish variants, high pressure
• Hadal Zone (1000m+) - Legendary-only spawns, extreme pressure

New Fish

The update adds 18 new fish species exclusive to the deep sea. Highlights include:

• Abyssal Lanternfish (Rare) - glows in the dark, sells for 450 Coins
• Giant Isopod (Epic) - the largest catchable creature yet
• Phantom Dragonfish (Legendary) - transparent body with visible skeleton
• Kraken Squid (Mythic) - 0.1% spawn rate in the Hadal Zone

Deep-Sea Gear

The new Pressure Suit system lets you survive at deeper levels. Upgrade your suit at the Dock Workshop using Deep Pearls (dropped by deep-sea fish). Each upgrade tier unlocks the next depth zone.

Tips for Deep-Sea Fishing

Bring plenty of Glow Bait - regular bait doesn't attract deep-sea fish. The Midnight Zone has the best Coins-per-hour ratio, but the Hadal Zone is where the trophy catches live. Watch your oxygen meter and surface before it runs out.
