Tracking every species in Fish It gets messy fast because the game advertises over a million possible fish variations spread across a growing set of islands. This fish it fish list breaks the catalog into practical chunks: which fish belong to which island, which ones are the best fish to catch for profit, and which secret variants are worth chasing beyond the base collection. Whether you are filling the index for the first time or hunting the Secret-rarity Megalodon, the tables and island breakdowns below give you a clear path forward.
Fish It Fish List Overview: How the Catalog Is Built
Fish It structures its collection around three rarity tiers — Common, Rare, and Secret — each tied to a specific island environment. Common fish fill the early-game index on starter islands and provide steady coin income for rod upgrades. Rare fish appear on mid and late islands, requiring better rods and luck boosts to hook consistently. Secret fish are the apex catches: extremely low spawn rates, often locked to one island, and valued in the high coin or unique-currency range. Recent updates added the Arcadia limited-time island, the Withering Core expansion, the 8-Bit mutation, and the new highest-rarity Forgotten Hydras fish according to the official Fish It game page.
The catalog is genuinely large, and the million-plus variation figure accounts for mutation multipliers layered on top of base species. A single Common Carp on Ocean might exist in dozens of mutated states once you factor in Lightning, Frozen, Inferno, and the new 8-Bit mutation. The base list below focuses on species rather than mutations to keep tracking manageable, but the same island logic applies to every variant.
| Rarity Tier | Typical Coin Value | Rod Requirement | Island Access |
|---|---|---|---|
| Common | Low (steady income) | Starter rod sufficient | All starter islands |
| Rare | Medium-High | Mid-tier rod recommended | Mid and late-game islands |
| Secret | Very High / Unique | Top-tier rod + luck boosts | Specific islands only |
Filling the index is a long-term project rather than a sprint, because the spawn rates for Secret fish sit well below one percent under normal conditions. Community reports suggest that stacking luck potions (obtainable through active codes), pairing the right rod, and fishing in the correct weather window can shorten the hunt dramatically. Players who ignore luck stacking often grind for weeks without seeing a single Secret catch.
Fish It All Fish by Island: Where Each Species Hides
The fastest way to complete the index is to fish where the species actually spawn. Fish It ties most species to a single island or a small island cluster, so traveling with purpose saves hours. The table below summarizes the major island hubs and the general category of fish you can expect from each, drawn from community data and the official game page listing.
| Island | Unlock Requirement | Primary Fish Category | Notable Catches |
|---|---|---|---|
| Ocean | Default starter | Common marine fish | Carp, Bass, Salmon variants |
| Tropical | Low coin unlock | Tropical reef species | Clownfish, Parrotfish, Manta |
| Coral | Mid-tier unlock | Coral reef and bottom-dwellers | Eel, Lionfish, Pufferfish |
| Arctic | Mid-tier unlock | Cold-water species | Arctic Cod, Icefish, Frost Shark |
| Volcanic | High-tier unlock | Lava-zone species | Lava Eel, Magmafish, Ember Shark |
| Withering Core | Endgame unlock | Corrupted and rare variants | Wither variants, Forgotten Hydras |
| Arcadia | Limited-time event | Mythic and event fish | Seasonal exclusives |
Each island has its own weather and time-of-day modifiers that influence spawn rates. Volcanic island catches spike during in-game storms, while Arctic species appear more reliably during overcast conditions. Players chasing the best fish to catch for profit should focus on Volcanic and Withering Core species once their rod is upgraded, because those zones consistently yield the highest base-coin fish before mutations are applied. For a deeper breakdown of every island's unlock cost and hidden spots, the Fish It all islands guide covers travel costs, weather windows, and the best fishing spots per zone.
Requirements for a Secret Spawn
Secret fish are where the catalog turns into a real grind. Unlike Rare fish which appear somewhat predictably on their home islands, Secret variants are gated by a combination of rod tier, luck stat, weather, and in some cases a server-wide event trigger. The Secret Megalodon — highlighted in a community noob-to-master walkthrough — requires a fully upgraded rod, stacked luck potions, and patient fishing in deep-water conditions. Most players report their first Megalodon catch after several real-time hours of focused farming on the correct island.
Fish It Best Fish to Catch for Profit and Progression
Not every fish on the list is worth your time. The best fish to catch are the ones that balance a reasonable spawn rate against a strong coin payout, so you can fund rod upgrades without burning out on a low-yield grind. Below is a ranked snapshot of which species deliver the best return per cast based on community data.
| Rank | Fish | Island | Coin Value (approx.) | Why It Pays |
|---|---|---|---|---|
| 1 | Forgotten Hydras | Withering Core | Very High | Newest Secret-tier, limited supply |
| 2 | Secret Megalodon | Deep-water islands | Very High | Apex Secret catch, trophy value |
| 3 | Ember Shark | Volcanic | High | Reliable Rare-tier spawn in storms |
| 4 | Thunderzilla | Storm-active islands | High | Event-gated Rare, strong payout |
| 5 | Magmafish | Volcanic | Medium-High | Steady Rare spawn, easy to farm |
| 6 | Arctic Frost Shark | Arctic | Medium-High | Cold-weather spawn boost |
| 7 | Lionfish | Coral | Medium | Decent payout, beginner-friendly |
Profit ranking shifts whenever a new island or mutation drops, but the principle stays the same: target Rare and Secret fish on their home islands during favorable weather, sell in bulk, and reinvest in rod upgrades. Mutations can multiply these base values by a significant factor, so a Rare fish with a strong mutation often outperforms a Secret catch without one. For players who want the full mutation layer, the Fish It all mutations guide breaks down the Lightning, Frozen, Inferno, 8-Bit, and other variants and their value multipliers.
Cashing Out vs Banking Rares
A common mistake is selling every catch immediately. Some players hoard Rare and Secret fish in anticipation of a value rebalance or a limited-time event multiplier. Community testing suggests that selling in bulk during a weekend event window tends to outperform selling on a strict daily schedule, because the event multipliers stack on top of mutation bonuses. That said, coins are useless if your rod is too weak to fish the next island, so balance the hold strategy against your upgrade path.
Fish It All Secret Fish: The Complete Roster
Secret fish are the headline catches and the reason most long-term players keep grinding. The roster expands with every major update, and the current list — based on the official game page and community reports — includes the following confirmed entries. Spawn rates for each sit well under one percent under normal conditions and improve only with stacked luck and the right rod.
| Secret Fish | Home Island | Notes |
|---|---|---|
| Megalodon | Deep-water islands | Apex trophy catch, requires stacked luck |
| Thunderzilla | Storm-active islands | Event-gated, lightning-themed |
| Forgotten Hydras | Withering Core | Newest Secret-tier, endgame content |
| 8-Bit Carp | Event windows | Tied to the 8-Bit mutation release |
| Ancient Eel | Coral (rare conditions) | Long-cycle spawn, high coin value |
| Ghost Shark | Arctic (night) | Weather and time-of-day gated |
The full secret fish list is not finalized because the developer adds entries with each island expansion, so the Fish It catch-all fish guide tracks the latest additions and their spawn conditions in real time. Joining the official Fish Atelier group is the most reliable way to catch new Secret drops the moment they go live, because the group page is where patch notes and limited-time events get announced first.
How to Improve Your Secret Catch Rate
Three levers actually move the needle on Secret spawn rates: rod luck stat, luck potions, and server conditions. Rod upgrades compound over time, so prioritize the highest luck-tier rod you can afford before chasing Secret fish. Luck potions from active codes or in-game events stack multiplicatively, which is why players who time their farming windows around code drops tend to see results faster. Finally, fishing on less-populated servers during off-peak hours can reduce competition for rare spawns in shared zones.
Fishing Strategy and Progression Tips
Beyond knowing which fish exist, the practical path to filling the index comes down to a few repeatable habits. The tips below are drawn from a beginner-to-advanced tips video and community testing, and they apply whether you are working through the Common tier or pushing for the Forgotten Hydras.
| Tip | Why It Works |
|---|---|
| Upgrade rod luck before chasing Rare fish | Higher luck stat directly increases Rare and Secret spawn odds |
| Stack luck potions from active codes | Multiplicative boost, free to claim and use |
| Fish during in-game weather events | Storms, fog, and night cycles boost specific species |
| Travel with purpose, not randomly | Each island hosts a specific subset of species |
| Sell Rare catches in bulk during events | Event multipliers stack on top of mutation bonuses |
| Join the official Fish Atelier group | First source for patch notes and limited-time drops |
A clean progression path looks like this: start on the default Ocean island to bank coins, unlock Tropical and Coral for a wider species pool, push to Arctic and Volcanic once your rod can handle the higher-tier fish, and finish on Withering Core and Arcadia for the Secret-tier payoff. Pets from Pet Egg hatches can add a passive luck bonus that smooths the grind, and the Fish It all pets guide ranks which companions are worth prioritizing early.
Fish Catching Mistakes to Avoid
Two errors cost new players the most time. The first is fishing on the wrong island — many species simply do not spawn outside their home zone, so traveling to the right location matters more than grinding volume. The second is selling Rare fish too early to chase a quick coin boost, which leaves you without the bankroll to fund a mid-game rod upgrade. Treat the index as a long-term project and the progression curve stays smooth.
Frequently Asked Questions
How many fish are in the Fish It fish list?
The exact species count grows with each update, but the current catalog includes roughly 100+ base species spread across Common, Rare, and Secret tiers, with over a million possible mutated variations. The Withering Core expansion and the 8-Bit mutation both added new entries, so the total keeps climbing. Check the official game page for the latest confirmed count.
Where do secret fish spawn in Fish It?
Each secret fish is tied to a specific island and often a weather or time-of-day condition. The Secret Megalodon favors deep-water islands, the Thunderzilla appears during storm events, and the Forgotten Hydras spawns exclusively on Withering Core. Stacking luck potions and fishing in the correct conditions is the only reliable way to force a Secret catch.
What is the best fish to catch for coins in Fish It?
For raw coin return, the Forgotten Hydras and Secret Megalodon sit at the top of the list, but they require endgame rods and stacked luck. For a more accessible grind, the Ember Shark and Magmafish on Volcanic island deliver strong Rare-tier payouts with a reasonable spawn rate. Mutations can multiply any of these base values significantly.
How do I unlock every island in the fish it all fish collection?
Each island has a coin unlock cost that scales with tier. Start on the default Ocean zone, save up for Tropical and Coral, then push to Arctic and Volcanic as your rod improves. Withering Core and Arcadia are endgame islands that require both coin and progression milestones. The Fish It all islands guide breaks down every unlock cost in order.
Are the fish it all secret fish affected by mutations?
Yes. Mutations apply to Secret fish the same way they apply to Common and Rare species, and a Secret catch with a strong mutation can be worth several times its base coin value. The new 8-Bit mutation is the latest example, and it stacks with existing variants like Lightning, Frozen, and Inferno for combined multipliers.
