Rare & Legendary Fish: Locations, Bait & Catch Tactics

How to Fish does not use a traditional 'Legendary' rarity label — instead, its rarest catches are the 12 boss fish (including the Pufferfish, Blue Shark, Goblin Shark, Oarfish-tier oddities aside, and the Mutated Bowhead Whale) plus a set of unusual codex species like the Sengarat, Voxelfish, and Blobfish. This guide lists every confirmed boss and rare fish, explains where the hunt takes place across the game's 5 islands, and covers what is currently confirmed about the bait system and boss-catching tactics — including the weapon-based approach that lets you kill a boss in under 10 seconds.

Does How to Fish Have Rare and Legendary Fish?

Yes — but not in the way most fishing games label them. Based on current wiki documentation (Game8), How to Fish has a fish codex of roughly 50 species, and the closest thing to a 'legendary' tier is its roster of 12 boss fish: massive marine creatures that gate your progression as you fish your way home after crashing your boat on a small island. There is no confirmed official 'Rare/Legendary' rarity grading in the game's UI at this time, so treat 'boss fish' and 'unusual codex species' as the two practical rarity tiers.

On top of bosses, the game has a separate Endangered Fish mechanic — a distinct category of hard-to-get fish with its own dedicated catching method (Game8 maintains a standalone 'How to Catch Endangered Fish' guide for it). Combined with special systems like Drip Creatures and the Reel of Fortune, the rare-fish chase in How to Fish spans three layers: boss fish, endangered fish, and oddball codex species.

One important caveat: How to Fish released on August 20, 2026, and community documentation is still young. Per-fish spawn depths, exact water zones, and bait-to-fish pairings have not been publicly documented yet. Everything below is verified against the Steam store page, Steam community discussions, and the Game8 wiki — and anything unconfirmed is explicitly marked as such.

• 12 boss fish serve as the game's de facto legendary tier
• A ~50-species codex includes multiple unusual rare fish
• A separate Endangered Fish mechanic exists with its own catch method
• No official 'Legendary' rarity label has been confirmed in-game

All 12 Boss Fish — The Legendary-Tier Catches

According to Game8's boss documentation, How to Fish features exactly 12 bosses, and all of them are large fish or marine creatures. This is the definitive checklist for players searching for the game's legendary fish. Note two standouts: the Pufferfish appears in both the regular fish list and the boss list — meaning it is a boss-level fish you can actually encounter and catch — and the Mutated Bowhead Whale is listed separately from the regular Bowhead Whale, indicating a strengthened mutated variant of the final-tier whale.

Boss fish are not bait-only encounters. The game has a full weapon system (with a Best Weapons tier list, weapon attachments, and upgrades documented on Game8), and bosses can be killed with weapons — there is even a documented achievement strategy called 'How to Kill a Boss in Under 10 Seconds.' If your rod work isn't landing the catch, gearing up with upgraded weapons is a confirmed alternative path to taking a boss down. Playing in 1-4 player online co-op (a verified Steam feature) also lets a full crew attempt these fights together.

Pufferfish (복어): The Boss Fish Everyone Is Searching For

If you arrived here searching '하우투피시 복어' (How to Fish Pufferfish), here is what is confirmed: the Pufferfish is one of the 12 bosses, and unlike some boss entries, it is also listed in the standard fish codex — Game8 lists it in both places. That dual listing makes it the clearest example of a catchable boss-class fish in the game, and likely one of the first legendary-tier targets most players will face.

Specific Pufferfish tactics — its location, required bait, drops, and fight pattern — have not yet been publicly documented, so we will not invent them here. What is confirmed and applicable: bosses can be defeated with weapons (fast enough that a sub-10-second boss kill is an achievement strategy), the game supports 1-4 player co-op for tackling encounters as a group, and the Save Anytime feature (a listed Steam feature) means you can save before committing to an attempt. We will update this section with exact Pufferfish mechanics as community data solidifies.

Rare & Special Fish in the Codex

Beyond the boss roster, the ~50-fish codex contains a cluster of unusual species that function as the game's rare-fish layer. Confirmed names from Game8's fish list include: Sengarat, Voxelfish, Dripper, Blobfish, Oarfish, Superdwarf Fish, Bowlfish, Yellow Boxfish, Anglerfish, Stonefish, Flying Fish, Goldfish, and Seahorse. Several of these (Sengarat, Voxelfish, Superdwarf Fish, Bowlfish) are invented species unique to this game, which is exactly the kind of entry that tends to sit at the top of a codex's rarity curve.

The Dripper deserves special attention: the game has a documented 'Drip Creatures' special-creature mechanic with its own guide, and the Dripper fish appears directly tied to it. Likewise, the Endangered Fish category is a separate mechanic with a dedicated catch method — if you are chasing 100% codex completion, plan for boss fish, endangered fish, and Drip Creatures as three distinct hunts. Individual spawn spots and sell values for these species are not yet documented; avoid any guide that claims exact numbers without sourcing.

• Unique invented species: Sengarat, Voxelfish, Superdwarf Fish, Bowlfish
• Real-world rare species: Blobfish, Oarfish, Yellow Boxfish, Anglerfish, Stonefish, Flying Fish
• Dripper — tied to the special Drip Creatures mechanic
• Endangered Fish — a separate mechanic with its own dedicated catching method

Where to Hunt: The Five Islands

How to Fish plays out across 5 confirmed islands, each with its own independent quest line: Island 1 (Lighthouse), Island 2 (Forest), Island 3 (Palm Trees), Island 4 (Casino Barn), and the Final Island (name partially documented as 'Volca…', very likely Volcano, though the full name is unconfirmed). Since the core loop is progressing island by island to eventually get home, rare-fish hunting naturally expands as you unlock new waters.

Honest status report: no source has yet published a per-fish location map — which island, which stretch of water, or what depth each rare fish spawns at is currently undocumented. The practical approach for now is to fish each island's waters thoroughly while completing its quest line, since Game8 structures its walkthrough island-by-island from Island 1 through the Final Island. Island 4's Casino Barn is also confirmed to host the game's casino/gambling element (mentioned in both Game8 and multiple Steam community threads), so budget your money accordingly before betting your rare-fish earnings at the tables.

• Island 1: Lighthouse — starting waters
• Island 2: Forest
• Island 3: Palm Trees
• Island 4: Casino Barn — confirmed in-game casino location
• Final Island: Volca… (full name unconfirmed, likely Volcano)

Bait & Catch Tactics: What's Confirmed So Far

The game has a dedicated bait system — Game8 maintains a standalone Baits category for it — but the specific bait-to-fish pairings (which bait attracts which rare fish) have not been publicly documented yet. Until that data lands, the confirmed tactical toolkit for rare and boss fish is: master the physics-based rod mechanics (this is a physics-based fishing simulator at its core), invest in the weapon system with attachments and upgrades for boss encounters, and bring friends — 1-4 player online co-op is a verified Steam feature.

Two more confirmed systems support your hunt. First, Save Anytime is an official Steam feature, which means you can save before a risky boss attempt rather than losing progress. Second, the game has documented difficulty differences, so your chosen difficulty will affect how these encounters play out (specifics unconfirmed). For boss fish specifically, the existence of the 'How to Kill a Boss in Under 10 Seconds' achievement strategy confirms that a well-upgraded weapon loadout can trivialize fights that a rod cannot.

What this guide deliberately does not tell you: exact bait recipes, spawn times, weather conditions, or per-fish reeling techniques — because no reliable source has published them yet. As Steam community guides and Game8's individual fish pages (Pufferfish, Sengarat, Oarfish, and the boss pages) fill in, this page will be updated with exact numbers rather than guesses.

• Learn the physics-based casting and reeling system — it is the core mechanic
• Use weapons, attachments, and upgrades as a confirmed boss-killing path
• Play 1-4 player co-op to tackle boss fish as a crew
• Save Anytime before risky attempts (official Steam feature)
• Bait system exists — specific bait-to-fish pairings are not yet documented
