Pull a Lucky FishBanking the right fish on your island is the single most important economic decision in Pull a Lucky Fish. Every fish you place on an island pedestal generates passive income over time, but not all fish are created equal. A pedestal occupied by a common catch will produce a trickle of cash, while the same slot holding a Secret-tier Voidfish can transform your economy. This guide ranks every fish by its island income value per slot, explains the mechanics behind passive earnings, and provides a replacement strategy to maximize your long-term gains.
How Island Income Works in Pull a Lucky Fish
The island serves as your personal banking system in Pull a Lucky Fish. After escaping the shark and reaching the safe zone, you can place any caught fish onto an island pedestal. Once banked, that fish begins generating a continuous stream of money. The income ticks every few seconds, accumulating even while you are offline, making it the truest form of passive progression in the game.
The core formula is straightforward: rarer fish produce significantly more income per tick than common ones. However, the relationship between rarity and income is not linear. A Secret-tier fish does not merely generate twice as much as a Mythic fish — the multiplier scales exponentially. This means that replacing a low-value fish with a high-value one yields compounding returns over time.
Pedestal slots are limited. Every player starts with a small number of slots, and additional slots can be unlocked through progression or purchased with Robux. Because slots are scarce, the goal is to fill each one with the highest-value fish possible. A single Voidfish occupying one slot generates more income than five slots filled with Epic-tier fish combined, according to community reports.
The shark encounter is directly tied to island banking. Every time you catch a fish, the shark spawns and chases you. If the shark catches you before you reach the island, you lose the fish and forfeit the opportunity to bank it. This risk-reward loop means that targeting high-value fish in Far Water — where the rarest species live — carries the greatest potential upside but also the greatest danger. Investing in Pull Power and Throw Power through training makes reaching Far Water and escaping the shark more manageable.
Offline income accumulation is capped at a certain duration, so logging in periodically to collect and reinvest earnings remains necessary. However, a well-optimized island with high-value fish will generate enough passive cash to fund rapid progression in rods, training, and gamepass purchases through earned currency alone.
Fish Tier List for Island Income Value
The following tier list ranks every known fish in Pull a Lucky Fish based on island income generation per pedestal slot. Rankings are determined by rarity tier, community testing data, and developer hints from Openwater Games. Values are estimated based on community reports, as the developers have not published official income-per-minute figures.
| Tier | Fish | Rarity | Estimated Income per Slot | Notes |
|---|---|---|---|---|
| S+ | Voidfish | Secret | Extremely High | Best passive income in the game; extremely rare |
| S | Prism Fish | Secret | Extremely High | Comparable to Voidfish; slightly lower income |
| A | Alien Fish | Mythic | Very High | Best non-Secret income option |
| A | Dolphin | Legendary | High | Reliable high-tier income |
| B | Sunfish | Legendary | Moderate-High | Good placeholder while hunting Mythic+ |
| B | Codfish | Epic | Moderate | Decent early-game income |
| C | Colorless Fish | Epic | Low-Moderate | Not worth long-term slot use |
| C | Puffer Fish | Rare | Low | Replace as soon as possible |
S-Tier: Voidfish and Prism Fish
Voidfish and Prism Fish are the ultimate island income generators. Both are classified as Secret rarity, placing them above Mythic in the game's loot hierarchy. The Voidfish is widely considered the single best fish for island income, with community estimates suggesting it generates approximately 5-8 times the income of a Legendary fish like the Dolphin. The Prism Fish is a close second, offering roughly 90-95% of the Voidfish's income output according to community reports.
These fish are found exclusively in Far Water, which requires significant investment in casting distance training to reach. Even with sufficient range, their catch rates are estimated at <1%. The x2 Fish Luck gamepass (225 Robux) is practically mandatory for anyone seriously hunting these fish. Combining Fish Luck with the Ice Rod — which reportedly offers approximately 2.5x luck, though this is unverified — creates the best odds currently known.
A single Voidfish on your island can fund rapid purchases of the remaining gamepasses through earned currency alone. The snowball effect is dramatic: bank one Secret fish, earn enough passive income to buy better rods and training, then catch more rare fish faster. This creates a compounding loop that accelerates all other progression.
A-Tier: Alien Fish and Dolphin
The Alien Fish sits at Mythic rarity, making it the strongest non-Secret income generator. Its island income is estimated at roughly 60-70% of a Secret fish, which still represents a massive boost over anything below it. The Alien Fish can be found in Far Water and occasionally in mid-range waters with enough luck and Fish Luck active.
The Dolphin is the best Legendary-tier option for island income. It generates consistent, high passive income and is significantly easier to catch than Mythic or Secret fish. Most players will use Dolphins as their primary income source while gradually hunting for Alien Fish, Prism Fish, or Voidfish. A full island of Dolphins provides enough passive income to fund all basic progression needs.
B-Tier and Below: Placeholders Only
Sunfish (Legendary) and Codfish (Epic) serve as acceptable placeholders. They generate enough income to be worthwhile in the early and mid-game, but should be replaced as soon as higher-rarity fish are caught. Colorless Fish (Epic) and Puffer Fish (Rare) should only occupy slots temporarily — their income is too low to justify long-term use.
Strategy for Replacing Low-Value Fish Over Time
Slot management is the art of maximizing island income. Every pedestal occupied by a low-value fish is a missed opportunity for higher passive earnings. The replacement strategy follows a simple rule: always replace your lowest-value fish first.
The Replacement Priority System
When you catch a new fish that is better than your current worst banked fish, immediately replace the lowest-income fish on your island. Do not hold empty slots waiting for a perfect catch — an Epic Codfish generating moderate income is better than an empty slot generating zero income. The replacement order should follow this priority:
| Priority | Action | Reasoning |
|---|---|---|
| 1 | Fill all empty slots immediately | Any income beats zero income |
| 2 | Replace Puffer Fish/Colorless Fish with Epic+ | Largest relative income jump |
| 3 | Replace Epic fish with Legendary+ | Significant upgrade |
| 4 | Replace Legendary fish with Mythic | Solid improvement |
| 5 | Replace Mythic fish with Secret | Endgame optimization |
Income Stacking with Mutations
Mutations add another layer to replacement strategy. The Bloody mutation and Moon-linked mutation are both unverified in their exact effects, but community reports suggest they provide income bonuses on top of the base rarity value. A mutated fish of a lower rarity might outperform an unmutated fish of a higher rarity. For example, a Bloody Dolphin could potentially out-earn a standard Alien Fish, though this is based on community estimates rather than confirmed data.
The x2 Mutation Luck gamepass (360 Robux) increases the chance of catching mutated fish. When combined with Fish Luck and a high-tier rod, mutation hunting becomes a viable strategy for maximizing per-slot income. However, given the unverified nature of mutation bonuses, prioritize rarity first and treat mutations as a bonus rather than a primary target.
Far Water and Rod Selection
Far Water is the only zone where Voidfish, Prism Fish, and Alien Fish spawn. Accessing it requires substantial investment in casting distance through the training system. The Ice Rod, estimated to cost around 50 million cash and provide approximately 2.5x luck, is the best known rod for hunting in Far Water according to community reports. The Crow Rod and Thunder Rod exist but have unverified stats; community consensus currently favors the Ice Rod for Secret fish hunting.
Pair the Ice Rod with the x2 Fish Luck gamepass for the highest possible luck stacking. The x2 Pull Power gamepass (99 Robux) helps bring fish in faster, reducing the time per catch cycle. The x2 Throw Power gamepass (315 Robux) increases casting distance, making Far Water accessible earlier. These gamepasses compound: faster catches plus better luck plus longer casts equals more opportunities at Secret fish per hour.
Gamepasses That Boost Island Income
Seven gamepasses are available in Pull a Lucky Fish, and several directly or indirectly improve island income. Here is a breakdown of each one's impact on your passive earning potential:
| Gamepass | Robux Cost | Effect on Island Income | Priority |
|---|---|---|---|
| x2 Fish Luck | 225 | Doubles chance at rare fish → better banked fish | Essential |
| x2 Mutation Luck | 360 | Higher mutation rate → potentially higher income per slot | High |
| x2 Cash | 360 | Doubles all cash earned, including passive island income | High |
| Auto Fishing | 49 | Automates casting, more catches per hour | Medium |
| x2 Pull Power | 99 | Faster reel speed, more catches per hour | Medium |
| x2 Throw Power | 315 | Longer casts, earlier Far Water access | Medium |
| Faster Rolling | 229 | Faster movement, quicker shark escapes | Low |
The x2 Cash gamepass deserves special attention. It doubles all cash earned, and community reports confirm this applies to passive island income. A Voidfish generating high base income doubled by this gamepass creates an enormous economic advantage. For players committed to long-term progression, x2 Cash is arguably the most impactful purchase after x2 Fish Luck.
Practical Tips for Maximizing Island Income
Start by filling every available pedestal slot, even with low-rarity fish. An Epic Codfish generating moderate income is infinitely better than an empty slot. Upgrade incrementally: when you catch a Dolphin, replace your lowest-value fish. When you catch an Alien Fish, replace the next lowest. This stair-step approach ensures your island income constantly trends upward.
Prioritize unlocking additional pedestal slots. Each new slot is a multiplier on your passive income potential. A full island of Dolphins will outperform a half-full island with one Voidfish, simply because more slots generating income compound faster than fewer slots with higher individual values.
Invest in Pull Power early. Faster reel-ins mean more catches per hour, which means more chances at rare fish. Combine this with Auto Fishing for semi-afk grinding sessions. The shark still requires manual evasion, but automatic casting removes the most tedious part of the loop.
Finally, bank immediately after every successful catch. The shark appears after every fish, and losing a rare catch because you got greedy trying to catch another before banking is a devastating setback. Escape the shark first, bank second, then return to fishing.

FAQ
How does island income actually work in Pull a Lucky Fish?
When you place a fish on an island pedestal, it begins generating cash at regular intervals. The income rate is determined by the fish's rarity — Secret fish generate the most, followed by Mythic, Legendary, Epic, and Rare. Income continues even when you are offline, making it the most efficient form of progression in the game. The x2 Cash gamepass doubles all island income.
Which fish is the absolute best for island income?
The Voidfish is universally considered the best fish for island income. As a Secret-tier fish, it generates the highest passive income per slot in the entire game. The Prism Fish is a very close second, with community estimates placing it at roughly 90-95% of a Voidfish's output. Both are found exclusively in Far Water with extremely low catch rates.
Should I keep lower-rarity fish on my island or leave slots empty?
Always fill empty slots, even with lower-rarity fish. Any income is better than zero income. Replace them as you catch better fish, but never leave a slot unused. The incremental income from an Epic Codfish adds up over hours of offline accumulation and helps fund the rods, training, and gamepasses needed to catch better fish.
Do mutations increase island income?
According to community reports, mutations like Bloody and Moon-linked do increase island income, though the exact multipliers are unverified. A mutated fish may outperform an unmutated fish of a higher base rarity in some cases. The x2 Mutation Luck gamepass increases mutation rates, making it a worthwhile investment for players focused on maximizing per-slot income.
