Strategies for Finding Each Fish

Strategies for Finding Each Fish

How to Catch Common Fish Efficiently?

For the common fish like Glow Minnow and Crystal Guppy, focus on the Shallow Glow and Crystal Depths areas. These fish spawn frequently throughout the day, but their activity increases during nighttime. Use basic worms for Glow Minnows and Glow Worms for Crystal Guppies. The Mythical Rod or better is recommended for faster catching, though a Standard Rod will work.

Techniques for Uncommon Fish

Neon Tetras and Biolume Bass require a bit more strategy. Neon Tetras tend to school together in the Shallow Glow streams, so look for groups of small, fast-moving fish. Biolume Bass prefer the deeper pools in Crystal Depths and are more active during rainy weather in the game. Using Shrimp for Neon Tetras and Squid for Biolume Bass will significantly increase your catch rate.

Hunting Rare Fish

Luminous Loaches and Phantom Pikes present a greater challenge. Luminous Loaches are found in the deep Crystal passages and are most active between 10 PM and 2 AM game time. They’re attracted to Glow Worms and tend to hide near crystal formations. Phantom Pikes, found in Abyssal Darkness, require Special Lures and are more likely to appear during thunderstorms. Patience is key here, as these fish have lower spawn rates.

Approaching Epic Fish

Spectral Sturgeons and Abyssal Anglers are among the most challenging catches in the cavern. Spectral Sturgeons require Ghost Bait and are found exclusively in Abyssal Darkness. They appear as semi-transparent fish that move slowly but put up a strong fight. Abyssal Anglers are located in the deepest parts of the cavern and are distinguished by their bioluminescent lures. Both fish require at least a Mythical Rod for a reasonable chance of success.

Legendary Fish Hunting

Crystal Carps and Glowfin Sharks are the legendary fish of the cavern. Crystal Carps are found in the center of Crystal Depths and require Crystal Bait. They appear as large, crystalline fish that reflect light beautifully. Glowfin Sharks can appear in any zone but have a very low spawn rate. They’re fast and powerful, requiring both Special Lures and a Mythical Rod or better. Nighttime fishing increases your chances of encountering these legendary species.

Catching Mythical Fish

The Ethereal Eel and Crystalfin Angelfish are the mythical fish that complete the bestiary. Ethereal Eels are found in Abyssal Darkness and require Ghost Bait. They appear as nearly invisible, with only a faint glow giving them away. Crystalfin Angelfish are the rarest fish in the cavern, found only in Crystal Depths with Crystal Bait. They have a very low spawn rate and appear as beautiful, crystalline fish with translucent fins. Both require the best equipment and maximum patience.

Essential Equipment and Items

Recommended Fishing Rods

To efficiently complete the Luminescent Cavern Bestiary, you’ll need:

  1. Mythical Rod (minimum for rare and above fish)
  2. Divine Rod (recommended for epic and legendary fish)
  3. Celestial Rod (best for mythical fish)

Each rod increases your chances of catching rarer fish and reduces the likelihood of them escaping.

Special Bait Types

The Luminescent Cavern requires specific bait types:

  1. Glow Worms (for Crystal Guppy and Luminous Loach)
  2. Ghost Bait (for Spectral Sturgeon and Ethereal Eel)
  3. Crystal Bait (for Crystal Carp and Crystalfin Angelfish)
  4. Special Lure (for Phantom Pike, Abyssal Angler, and Glowfin Shark)

These can be purchased from the bait vendor near the cavern entrance or crafted using materials found within the cavern.

Advanced Tips and Strategies

Environmental Factors

Several environmental factors affect fish spawning in the Luminescent Cavern:

  1. Time of Day: Most luminous fish are more active at night (game time 8 PM – 6 AM)
  2. Weather: Rain and thunderstorms increase spawn rates for certain species
  3. Server Population: Less crowded servers tend to have higher spawn rates for rare fish
  4. Fishing Sequence: Some players report better results when catching fish in a specific order

Special Techniques

  1. “Patience Method”: Cast your line and wait 2-3 minutes without reeling in, which can attract rarer fish
  2. “Zone Cycling”: Move between different zones every 15-20 minutes to refresh spawns
  3. “Bait Rotation”: Change bait types every 10 catches to maintain effectiveness
  4. “Night Focus”: Concentrate your fishing efforts during nighttime hours for better results

Common Mistakes to Avoid

  1. Using the wrong bait for specific fish species
  2. Fishing in crowded servers during peak hours
  3. Not upgrading your rod before attempting rare fish
  4. Ignoring environmental factors like weather and time
  5. Giving up too quickly when hunting for mythical fish

Tracking Your Progress

The game provides a bestiary interface where you can track which fish you’ve caught:

  1. Open your inventory and select the “Bestiary” tab
  2. Navigate to the “Luminescent Cavern” section
  3. Fish you’ve caught will appear in color, while uncaught fish remain grayed out
  4. Each fish entry shows size records and the number of times caught
  5. Completing the bestiary rewards you with a special Luminescent Rod and 10,000 coins

Frequently Asked Questions

How long does it take to complete the Luminescent Cavern Bestiary?

On average, players report taking 15-25 hours to complete the bestiary. This varies based on your fishing level, equipment quality, and luck with rare spawns. The mythical fish, particularly the Crystalfin Angelfish, often take the longest to find.

Can I complete the bestiary with a standard fishing rod?

While technically possible for the common and uncommon fish, you’ll need at least a Mythical Rod for the rare fish and above. Attempting to catch epic, legendary, or mythical fish with a standard rod will result in them escaping almost every time.

Is there a specific order that makes completing the bestiary easier?

Many experienced players recommend catching fish in order of rarity (common to mythical). This approach allows you to familiarize yourself with the cavern layout and fish behaviors before tackling the more challenging species.

Do seasonal events affect the Luminescent Cavern fish?

Yes, during special seasonal events like the “Luminous Festival” or “Crystal Celebration,” spawn rates for certain fish increase. These events are excellent opportunities to complete difficult entries in your bestiary.

Can I trade with other players to complete my bestiary?

No, fish cannot be traded between players. Each player must catch all fish themselves to complete their personal bestiary. However, players can share tips on locations and timing for specific fish.

What happens if I miss a seasonal fish?

Seasonal fish that appear during special events will return in future iterations of the same event. The game developers typically repeat major events annually, so you’ll have another opportunity to catch these fish.

Are there any secret fish in the Luminescent Cavern?

As of the current update, there are no officially confirmed secret fish in the Luminescent Cavern. However, rumors persist about a “Void Leviathan” that appears under specific conditions, though this remains unverified.

How do I increase my chances of finding mythical fish?

To maximize your chances of finding mythical fish:

  1. Fish during nighttime hours
  2. Use the best possible rod (Celestial Rod preferred)
  3. Fish in less crowded servers
  4. Use the correct bait (Ghost Bait for Ethereal Eel, Crystal Bait for Crystalfin Angelfish)
  5. Fish during special events when spawn rates are increased

Conclusion

Completing the Luminescent Cavern Bestiary in Fisch is a challenging but rewarding endeavor that showcases your dedication as an angler.
