Every secret catch in Heavyweight Fishing lives behind a weather lock, and missing the right sky means the rod stays empty. This guide catalogs every confirmed heavyweight fishing all secret fish entry, from the Bamboo Isle storms that surface a Crimson Electric Eel to the Blazing Sun afternoons on Amber Isle where the Draconic Koi circles the shallows. Because each heavyweight fishing secret fish locations pairing is bound to one of the six biomes, planning an island run is really about planning the weather forecast first.
The community information board — a player-compiled Trello that the developers acknowledge but never publish through official channels — currently tracks sixteen entries across the heavyweight fishing rare fish, legendary fish, and boss fish families. Drop payouts, weather codes, and island names below are sourced from that board and should be treated as community data that may lag the live build.
How Weather Locks Gate Every Secret Fish
Each island in Heavyweight Fishing rotates through one signature weather condition, and secret spawns are pinned to that rotation rather than a global clock. According to the player-compiled information board, Thunderstorm belongs to Bamboo Isle, Rainy to Fallout Isle, Windy to Perch Isle, Snowy to Frost Isle, Foggy to Coconut Isle, and Blazing Sun to Amber Isle. Because no two islands share the same weather, choosing where to cast is the same decision as choosing which secret family to target.
Weather and Island Pairing
| Weather | Island | Common Secret Family |
|---|---|---|
| Thunderstorm | Bamboo Isle | Scarlet / Electric variants |
| Rainy | Fallout Isle | Verdant variants |
| Windy | Perch Isle | Flying Fish variants |
| Snowy | Frost Isle | Frost King / Queen |
| Foggy | Coconut Isle | Rare rotations |
| Blazing Sun | Amber Isle | Draconic / Sanguine |
The Spirits island set also keys off these pairings, which is what makes weather the central planning axis for any secret-fish run. Players chasing the heavyweight fishing all secret fish completion log should think of islands as a weather wheel rather than a level ladder.
Confirmed Secret Fish Roster
Sixteen entries appear in the community information board as of the most recent 8/8 patch card. All payouts below are listed in Gems, the in-game currency spent at the Maoshan Merchant and Taoist Merchant. The board does not publish drop-rate percentages for individual secret fish, only the flat Gem reward and any rod or skill attached as a chance drop.
Bamboo Isle — Thunderstorm
| Secret Fish | Weather | Reward | Extra Drop |
|---|---|---|---|
| Crimson Electric Eel | Thunderstorm | 5 Gems | — |
| Scarlet Fish | Thunderstorm | 3 Gems | — |
| Elder Scarlet Fish | Thunderstorm | 5 Gems | — |
| Verdant Bonefang | Thunderstorm | 3 Gems | — |
The four Bamboo Isle entries share a single sky condition, which means a single Thunderstorm run can in theory surface any of them. According to community reports, the Scarlet Fish is the most common spawn, while the Elder Scarlet Fish shows up only on extended storms.
Fallout Isle — Rainy
| Secret Fish | Weather | Reward |
|---|---|---|
| Verdant Alligator Gar | Rainy | 3 Gems |
| Verdant Grouper | Rainy | 3 Gems |
Fallout Isle has the smallest secret catalog on the board, with just two Verdant variants tied to the Rainy forecast. Both pay 3 Gems and have no recorded bonus drops, making them a steady side objective for anglers pushing the Verdant set.
Perch Isle — Windy
| Secret Fish | Weather | Reward | Extra Drop |
|---|---|---|---|
| Flying Fish Empress | Windy | 10 Gems | Hellbreaking Hook (10%) |
| Flying Fish Emperor | Windy | 10 Gems | Hellbreaking Hook (10%) |
The Perch Isle Windy bracket offers the highest flat Gem payout in the game at 10 per catch, and the 10% chance to drop the Hellbreaking Hook skill makes this the most rewarding run in the roster. The Hellbreaking Hook is one of the heavier skills on the Heavyweight Fishing skills tier list, so any Windy weather at Perch Isle is worth committing to.
Frost Isle Snowy Spawn Table
| Secret Fish | Weather | Reward |
|---|---|---|
| Frost Kingfish | Snowy | 3 Gems |
| Frost Queen Fish | Snowy | 3 Gems |
| Rainbow Dragon Fish | Snowy | 3 Gems |
Frost Isle's Snowy cycle carries three entries with identical 3-Gem payouts. The Rainbow Dragon Fish stands out as a heavyweight fishing legendary fish in feel, but the board still lists it at the same 3-Gem baseline as the rest of the Frost family.
Coconut Isle Foggy Spawn Table
| Secret Fish | Weather | Reward |
|---|---|---|
| Tigerfang Whale | Foggy | 3 Gems |
| Reborn Puffer Beast | Foggy | 3 Gems |
Foggy conditions at Coconut Isle surface the Tigerfang Whale and the Reborn Puffer Beast, both at 3 Gems. The board does not record any bonus rod or skill drop for these entries, so the value here is set-completion rather than raw payout.
Amber Isle Catches Under Blazing Sun
| Secret Fish | Weather | Reward |
|---|---|---|
| Draconic Koi | Blazing Sun | 5 Gems |
| Sanguine Fish | Blazing Sun | 3 Gems |
| Heaven Piercer Turtle | Blazing Sun | 3 Gems |
The Blazing Sun forecast on Amber Isle delivers the Draconic Koi, which is the headline heavyweight fishing legendary fish of that biome at 5 Gems. The Heaven Piercer Turtle shares its name with the Heaven Piercer Rod from the rod progression track, but the board treats them as separate entries.
Boss Fish vs Secret Fish
The community information board separates heavyweight fishing boss fish from the secret catalog, and the two systems use different gating. Bosses are tied to level milestones and difficulty mode (Easy 20K HP / Hard 40K HP for Enzo, who unlocks at level 1000), while secret fish are tied to weather. Players running completion logs need to clear both tracks separately.
Comparison Table
| Category | Gate | Highest Reward | Reset |
|---|---|---|---|
| Secret Fish | Weather + Island | 10 Gems (Flying Fish Emperor) | Weather rotation |
| Boss Fish | Level + Mode | 5 Gems (Enzo base) | Per-spawn cooldown |
Enzo drops Crystals, which the board lists as a separate currency from Gems and Essences, so converting between them is not a published mechanic. Players building the heavyweight fishing all secret fish completion log should treat the secret track and the boss track as parallel grinds rather than a single ladder.
How to Beat the Weather-Locked Spawns
Catching a heavyweight fishing secret fish requires three layers of preparation: the right island, the right weather, and a rod that can survive the weight class. The board does not publish a recommended rod for any individual secret, but community testing points to the higher-tier rods in the progression track.
Recommended Loadout for Secret Runs
| Layer | Suggested Option | Why |
|---|---|---|
| Rod | Diamond Rod or higher | Power threshold for heavier pulls |
| Bait | Elite Bait or Ancestral Bait | Increases rare spawn chance |
| Weather | Match island signature | Required for spawn |
| Island | Match weather code | Required for spawn |
Anglers building toward the heaviest catches report that the Pure Diamond Rod and Heaven Piercer Rod tier feels like the practical floor for boss-tier pulls, while the Inferno Rod and Bloodfire Rod fill the mid-game gap. For secret-fish specifically, the Emerald Rod or Steel Rod lines are enough for the 3–5 Gem entries, but the 10-Gem Flying Fish variants benefit from stepping up to the Diamond Rod or beyond.
How to Catch Secret Fish Step by Step
-
Check the current weather for the target island using the in-game sky state — the board's pairing table is the only published key.
-
Teleport or sail to the matching island during the active weather window.
-
Equip a rod that meets the weight class — Diamond Rod tier or higher for the 10-Gem Perch Isle entries.
-
Cast at the island's secret hotspot — the board does not publish a hotspot map, so community reports point to the perimeter of each island rather than the dock.
-
Reel in using the standard heavy-fish minigame — secret fish use the same bar as regular heavy catches.
-
Bank the Gems at the Maoshan Merchant or Taoist Merchant to roll for higher-tier rods.
The full rotation is documented on the Heavyweight Fishing island progression guide, which covers how each island transitions between weather cycles and how to chain the heavyweight fishing secret fish locations across a single play session.
Cross-Reference With Nightmare Mode and Orbs
Several secret-fish routes intersect with the Spirits banner and the Nightmare Mode unlock path. Because the Spirits islands use the same weather pairings as the secret catalog, completing a secret run on a given island often doubles as Spirits progression. The community information board currently does not publish a multiplier for that overlap, so the value comes from time saved rather than extra Gems.
Orbs play a role in the late-game build, and the heavyweight fishing all secret fish completion log is a common prerequisite for players pushing the orb value track. None of the orb entries — Maoshan Orb, Taoist Orb, Qian Gate Orb, Sage Yijiu Orb, Cloud Ascension Orb, Bac Minh Orb, or Execution Orb — is gated by a specific secret fish, but the Gem payouts fund the reroll economy that players use to chase them.
Common Mistakes When Chasing Secret Fish
-
Reading the wrong sky state — the board's six weather codes are island-locked, not global. A Foggy reading at Frost Isle is not the same as the Coconut Isle Foggy cycle that surfaces the Tigerfang Whale.
-
Assuming secret fish are level-gated — only bosses use level milestones. Secret fish are weather-gated, so a level 1 account can technically pull a Draconic Koi on Amber Isle during a Blazing Sun.
-
Banking Gems at the wrong vendor — the Maoshan Merchant and Taoist Merchant carry different inventories, so it is worth checking both before spending.
-
Ignoring the 10% Hellbreaking Hook drop — the Flying Fish Empress and Emperor both carry a 10% chance of the Hellbreaking Hook skill, which is one of the highest-impact skills in the heavyweight fishing how to beat bosses loop.
Frequently Asked Questions
What is the rarest heavyweight fishing all secret fish?
The community information board lists the Flying Fish Empress and Flying Fish Emperor at 10 Gems each — the highest flat payout in the secret catalog — with a 10% chance of dropping the Hellbreaking Hook skill. Because only Perch Isle's Windy cycle spawns them, they are widely treated as the rarest heavy pulls in the roster.
How does the weather lock actually work?
Each of the six biomes rotates through one signature weather code: Thunderstorm at Bamboo Isle, Rainy at Fallout Isle, Windy at Perch Isle, Snowy at Frost Isle, Foggy at Coconut Isle, and Blazing Sun at Amber Isle. The board treats weather as island-bound rather than global, so two players on different islands can see different skies in the same session.
Can secret fish drop rods or skills?
Yes. The Flying Fish Empress and Emperor both carry a 10% chance of dropping the Hellbreaking Hook skill. The board does not list any rod drops for the rest of the secret catalog, so the skill drop is the standout bonus of the Perch Isle Windy cycle.
How is a heavyweight fishing boss fish different from a secret fish?
Boss fish are gated by level and mode — for example, Enzo unlocks at level 1000 with 20K HP on Easy and 40K HP on Hard. Secret fish are gated by weather and island. The two tracks pay out in different currencies (Gems vs Crystals) and do not share a published conversion rate, so they are best treated as parallel grinds.
Do secret fish payouts change between difficulties?
The community information board does not publish a difficulty multiplier for any secret fish, only the flat Gem reward. Players comparing the heavyweight fishing all secret fish payouts across Easy and Hard modes report identical rewards, but the board has not formally confirmed this and the figures may shift with future patches.
