A complete Fish It rare fish list is the single most useful resource for anyone chasing the game's most valuable catches, because secret-tier and mythic-tier fish pay out more coins per cast than every common and uncommon species combined. The challenge is that the roster is huge, with over 1,000,000 possible variants spread across the islands, so players who chase random pools waste rods, bait, and luck potions. This guide collects the rarest confirmed catches, ranks them by sell value, and shows where each one actually spawns.
Rarity Bands, from Common to Secret
Fish It groups every catch into seven rarity tiers, and each tier multiplies the base sell value of a fish by a different factor. The current ordering, reported by players on community indexes, is Common, Uncommon, Rare, Epic, Legendary, Mythic, and Secret. The dev team has been adding hybrid fish like the Forgotten Hydras and the 8-Bit mutation, but the seven-tier structure is still the backbone of the economy.
The rare fish list is the layer where grinding starts to feel rewarding. Anything at Epic or above tends to feature a unique model, a special sell value, and a permanent entry in the fish log that other players will notice. Fishing at this tier also tends to be a more deliberate activity, because the chance of pulling an Epic or Legendary per cast is small enough that luck boosts, weather, and bait all matter.
Rarity Tiers at a Glance
The table below summarizes the seven tiers, the approximate sell multiplier reported by the community, and how the tier tends to feel in a normal session. Multipliers are approximate because recent updates added new fish with custom values that break the old curve.
| Rarity Tier | Approx. Sell Multiplier | Typical Pull Rate | Example Catches |
|---|---|---|---|
| Common | 1x | Very frequent | Small Fry, Anchovy |
| Uncommon | 3-5x | Frequent | Tuna, Mackerel |
| Rare | 10-15x | Occasional | Sturgeon, Catfish |
| Epic | 50-100x | Uncommon | Coelacanth, Giant Squid |
| Legendary | 200-500x | Rare | Megalodon, Kraken |
| Mythic | 1,000-5,000x | Very rare | Hydra variants, Ancient Koi |
| Secret | 10,000x+ | Extremely rare | Flame Tyrant, Forgotten Hydra |
What Makes a Catch "Secret"
The Secret tier is the rarest class in the game. Secret fish sit at the top of the Fish It rare fish list and serve as long-term chase goals. A catch only counts as Secret when it carries a custom model, a unique entrance animation, and an entry in the secret tab of the player's collection log. Examples include the Flame Tyrant, the Forgotten Hydra family, and certain limited-time additions tied to the Arcadia island event.
A practical way to confirm whether something is a Secret fish is to look at the journal entry icon. Community data shows Secret fish show a small flame or skull beside their name, while Mythic fish show a crown, and Legendary fish show a star. This visual cue is reliable as of the most recent patch and is the fastest way to know whether a pull is worth celebrating.
The Top Catches on the Fish It Rare Fish List
The rarest fish in the game are spread across the secret and mythic tiers, and each one ties to a specific location, weather, or bait condition. The table below covers the most valuable confirmed catches, including the legendary Megalodon, the mythic-tier Hydra family, and the secret Flame Tyrant. Values are drawn from community indexes and may shift with future updates.
| Fish Name | Rarity | Approx. Sell Value | Best Location | Notes |
|---|---|---|---|---|
| Megalodon | Legendary | 500,000+ | Open Ocean (mid-island) | Boosted by Shark Bait |
| Kraken | Legendary | 350,000 | Coral Reef deep zone | Spawns during Storm weather |
| Colossal Squid | Legendary | 280,000 | Frozen Sea (snow biome) | Tied to Ice mutation |
| Hydra (base) | Mythic | 1,200,000 | Ancient Ruins | Group of 3 heads |
| Forgotten Hydra | Mythic | 2,000,000+ | Withering Core expansion | Newest mythic-tier family |
| Ancient Koi | Mythic | 900,000 | Pond area, any island | Glows when wet |
| Flame Tyrant | Secret | 10,000,000+ | Volcanic Island lava zone | Requires Heat mutation |
| Bone Whale | Secret | 7,500,000 | Shipwreck Graveyard | Limited event windows |
Megalodon — The Anchor of Every Rare Fish List
The Megalodon is the fish most players think of when they hear "rare fish" in Fish It. It sits at the Legendary tier, pulls reliably from the Open Ocean mid-island waters, and has a sell value high enough to make any early-game player rich if they grind consistently. Community walkthroughs show that the Megalodon responds to Shark Bait and that luck potions noticeably raise the pull rate.
The Megalodon is a useful benchmark because it behaves like a ceiling for most pre-endgame players. Anyone who can clear a Megalodon in a normal session usually has the rod level, the bait stock, and the coin buffer to start experimenting with Mythic and Secret catches. Players who want a deeper look at catching strategies for fish at and above this tier can check the legendary catch guide for setup recommendations.
Mythic Fish and the Hydra Family
The Mythic tier is where the rare fish list shifts from a grind into a hunt. The base Hydra, the recently added Forgotten Hydra family, and the Ancient Koi sit at the top of the regular catch pool. Each one is tied to a specific biome, and most require a fully upgraded rod and a luck potion stack before they appear on a player's radar.
The Forgotten Hydras stand out because they were added in the Withering Core expansion, which is the current endgame zone. As of the latest patch, the family includes six variants, each with a custom model and a sell value that dwarfs the original Hydra. Players running the full variant list should treat the Withering Core as a Mythic-only zone, because common fish almost never spawn there.
Flame Tyrant — The Top Secret Catch
The Flame Tyrant sits at the top of the Secret tier and is the single most valuable fish on the rare fish list. The catch is gated by the Heat mutation, which only triggers near the volcanic vent on Volcanic Island, and the pull rate is so low that most players run hundreds of casts before seeing the entrance animation. Once landed, however, a Flame Tyrant can fund a full rod upgrade and a large potion stockpile in a single sale.
The practical route to a Flame Tyrant involves three steps: reach Volcanic Island with a fully upgraded rod, apply a luck potion stack, and fish the lava zone during the in-game Heat event window. Players who lack one of these three pieces tend to leave Volcanic Island empty-handed even after long sessions, so the exploring guide is worth a read for anyone who has not unlocked the island yet.
How to Catch Secret Fish in Fish It
Catching a Secret-tier fish is a multi-step process, and the steps look very different from normal fishing. The sequence below is the routine most community-recommended players use, and each step has a specific reason for being there. Skipping a step is the most common reason that a "secret farm" turns into a coin drain.
Step 1 — Unlock the Required Island
Every Secret fish is locked to a specific island or biome. The Flame Tyrant lives in the Volcanic Island lava zone, the Bone Whale lives in the Shipwreck Graveyard, and the Forgotten Hydras live in the Withering Core. Unlocking these islands requires coin, certain level thresholds, and sometimes a questline completion. Players who try to catch a Secret fish on the wrong island will not see the catch, no matter how lucky they are.
A solid way to know whether the island is unlocked is to check the travel menu. Locked islands show a small padlock icon, and the unlock cost is displayed in the tooltip. The fastest path is usually to grind a few Legendary catches first, then cash them in for the coin needed to unlock the next island.
Step 2 — Stack Luck Potions and Use the Right Bait
Luck is the single most important stat for Secret fish, because the base pull rate is already tiny. The most effective setup reported by players is two or three luck potions combined with the bait that matches the target fish. Shark Bait for the Megalodon, Heat Bait for the Flame Tyrant, and Hydra Bait for the Forgotten Hydras are the most common recipes.
The exact recipe for each bait rotates with updates, and the active codes page is the most reliable place to find the current list. The active codes for Fish It, including the luck and mutation potions used in these setups, are documented on TheGamer's Fish It codes guide, which is the most frequently updated community resource.
Step 3 — Fish the Right Window
Most Secret fish respond to weather, time of day, or in-game events. The Flame Tyrant is much easier to pull during the Heat event window, the Bone Whale spawns more often during fog, and the Megalodon pulls spike during storms at sea. Players who fish at the wrong time will see the same Epic and Legendary fish as a normal session.
The simplest way to wait for the right window is to server-hop or to sit near the fish's preferred zone until the weather or event changes. The Withering Core is currently the only zone with constant event activity, because the Forgotten Hydra family ignores the standard weather cycle.
Step 4 — Read the Entrance Animation
Secret fish announce themselves with a short entrance animation that is unique to each species. Reading the animation is a small but useful skill, because it confirms the catch before the sell menu opens. Players who skip this step sometimes sell a Secret fish at the wrong price by accident, or they sell a Mythic fish thinking it was a Legendary.
The animation library is small enough to memorize after two or three catches. The Flame Tyrant has a lava burst, the Bone Whale has a long skeleton rise, and the Forgotten Hydra has a three-headed scream. Once these are familiar, the Secret tier is impossible to miss.
Build, Rod, and Bait Recommendations
Rods, bait, and pet loadouts are the variables that separate an average catch from a record-breaking catch. The endgame setup for chasing the rare fish list is consistent across most community guides, with only a few specific swaps. Players who run this build from a clean save tend to reach the Secret tier within two to three weeks of focused play.
| Slot | Recommended Choice | Reason |
|---|---|---|
| Rod | Trident of the Deep | Highest luck stat at endgame |
| Bait | Heat Bait / Hydra Bait | Targets Secret and Mythic fish |
| Potion | 3x Luck Potion | Stacks the catch chance |
| Pet | Phoenix or Kraken | Adds passive luck |
| Location | Withering Core | Best Mythic density |
Rod upgrades should follow the in-game questline, because skipping a tier usually means missing a luck breakpoint. The Trident of the Deep is widely reported as the strongest endgame rod, but it requires the Withering Core questline to be fully complete, which means players should plan the unlock order around this rod.
The pet slot is often overlooked. The Phoenix pet adds a passive luck bonus that stacks with potions, and the Kraken pet adds a coin multiplier that compounds the value of every catch. Either one works as a starter pet, but endgame players usually run both through a pet egg cycle.
Where to Find Each Secret and Mythic Fish
A rare fish list is only useful if it tells the reader where to actually go. The table below pairs each of the top Secret and Mythic catches with the location, weather, and bait combo that players report as the most efficient. The data is drawn from community indexes and is the most current information available.
| Fish | Location | Weather | Bait |
|---|---|---|---|
| Megalodon | Open Ocean (mid) | Storm | Shark Bait |
| Kraken | Coral Reef deep | Storm | Ink Bait |
| Colossal Squid | Frozen Sea | Snow | Ice Bait |
| Ancient Koi | Pond area | Any | Lotus Bait |
| Hydra (base) | Ancient Ruins | Any | Hydra Bait |
| Forgotten Hydra | Withering Core | Constant | Hydra Bait |
| Flame Tyrant | Volcanic Island lava | Heat event | Heat Bait |
| Bone Whale | Shipwreck Graveyard | Fog | Bone Bait |
Players who want a more complete list of every fish in the game, including the common and uncommon pools, can browse the main fish list for the full index. The full list also covers variant rules and the 1,000,000+ variation system, which is useful background for anyone working on a full collection log.
The fish variants guide is a useful companion for understanding why the same fish can sell for wildly different amounts. Mutations like Heat, Ice, and 8-Bit all multiply the base value, and a Heat-mutated Megalodon will sell for far more than a base Megalodon. This is the mechanic that turns a Legendary into something that competes with a Secret-tier fish in value.
Common Mistakes When Chasing Rare Fish
Most players who fail to catch a Secret or Mythic fish are not bad at fishing — they are repeating one of a few common mistakes. The list below covers the mistakes that show up most often in community reports. Each one has a specific fix, and the fix is usually cheaper than the cost of a wasted session.
| Mistake | Why It Hurts | Fix |
|---|---|---|
| Fishing without luck potions | Cuts the pull rate by half | Stack 2-3 luck potions |
| Wrong bait for the target | Target fish never appears | Use the bait that matches the biome |
| Fishing the wrong weather | Secret fish stay locked | Wait for Heat, Storm, or Fog |
| Selling too early | Loses mutation bonus | Check mutation before selling |
| Skipping rod upgrades | Caps the luck stat | Upgrade to Trident of the Deep |
The most expensive mistake on this list is selling too early. A Heat-mutated Flame Tyrant is worth many times more than a base Flame Tyrant, and players who sell at the first prompt lose the mutation bonus permanently. The in-game sell menu shows the mutation clearly, and it is always worth pausing for two seconds to confirm before confirming the sale.
The second-most expensive mistake is fishing the wrong biome. Players who run out of luck potions often try to compensate by fishing longer in the same spot, but the better play is to leave and grind a few Legendary fish until the potion stockpile recovers. This is faster, cheaper, and tends to produce more useful upgrades along the way.
Rare Fish List FAQ
What is the rarest fish in Fish It?
The Flame Tyrant is currently the rarest confirmed catch, sitting at the Secret tier with a sell value over 10,000,000 coins. It is gated by the Heat mutation and the Volcanic Island lava zone, and the pull rate is low enough that most players report hundreds of casts before seeing one.
How do I catch the Megalodon in Fish It?
The Megalodon pulls from the Open Ocean mid-island waters during Storm weather, and the pull rate spikes with Shark Bait and a luck potion stack. A fully upgraded rod and the Trident of the Deep are recommended because lower-tier rods cap the luck stat.
Where do I find mythic fish in Fish It?
Mythic fish live in three main biomes: the Ancient Ruins for the base Hydra, the Withering Core for the Forgotten Hydra family, and any pond area for the Ancient Koi. Each biome has its own weather and bait requirements, which the mythic fish guide breaks down in more detail.
How do I unlock the Flame Tyrant?
The Flame Tyrant requires Volcanic Island to be unlocked, the Heat mutation to be active, and Heat Bait in the inventory. Players usually prep by stacking luck potions, fishing until the Heat event triggers, and then pulling from the lava zone until the entrance animation appears.
Are the rare fish values final?
No, sell values rotate with major patches and limited-time events. The values in this rare fish list reflect the most recent community data and may shift with the next Withering Core or Arcadia event update, so checking the in-game sell menu before trading large catches is always recommended.
