Mutated fish are one of the best ways to increase your profits in Pull a Lucky Fish. Unlike normal fish, mutated variants not only have a unique visual appearance but also generate more passive income while placed in your base and sell for much higher prices. Building a collection of powerful mutations is one of the fastest ways to earn more money and progress through the game.
This guide covers everything you need to know about Pull a Lucky Fish mutations, including every method to obtain mutated fish, all current mutation effects, and which weather events give you the highest chances of finding specific mutations.
How to Get Mutated Fish in Pull a Lucky Fish
There are currently three different ways to obtain mutated fish in Pull a Lucky Fish. Some rely entirely on luck, while others become available after reaching certain progression milestones. Understanding each method makes it much easier to build a base full of high-value fish.
Natural Mutation Spawns
Some mutations can appear naturally whenever you cast your fishing line. These mutations are completely random, meaning every catch has a chance of becoming a special variant instead of its standard version.
Currently, the mutations that can naturally appear include:
- Gold
- Diamond
- Molten
Although the odds aren’t guaranteed, continued fishing will eventually reward you with naturally mutated fish, especially during certain weather events that increase their appearance rates.
Take Advantage of Weather Events
Weather events are one of the most reliable ways to farm mutations. These limited-time events temporarily change the world and increase the chances of catching fish with specific mutations.
In addition, weather effects don’t just apply to newly caught fish. They can also affect fish that are already displayed inside your base, making these events even more valuable for growing your collection.
The current weather events include:
- Thunder
- Rainbow
- Cat
- Frozen
- Bloodmoon
Each event is tied to particular mutations, making it worthwhile to fish actively whenever your preferred weather appears.
Unlock the Mutation Machine
Players looking for more control over mutations should unlock the Mutation Machine.
This feature becomes available after completing four Rebirths. Once unlocked, you’ll find the machine on the left side of the main lobby. Instead of relying completely on luck, the Mutation Machine allows you to apply mutations directly to eligible fish stored in your inventory.
For players focused on maximizing income, reaching four Rebirths should be a priority since it provides a much more consistent way to obtain valuable mutations.
Every Mutation in Pull a Lucky Fish
As of the Trading Update, there are six different mutations available. Each one increases both the fish’s selling price and the amount of passive income it generates while placed inside your base.
Gold Mutation
The Gold mutation increases both the sale price and passive earning rate by 1.5x.
Although it can appear naturally, players have a better chance of finding Gold fish during:
- Thunder Weather
- Rainbow Weather
Gold is one of the earliest profit-boosting mutations and provides a noticeable upgrade over regular fish.
Diamond Mutation
Diamond doubles the value of a fish, giving it a 2x multiplier for both selling and passive earnings.
Your best opportunities to obtain Diamond fish are:
- Rainbow Weather
- Natural spawning
Because of its solid multiplier, Diamond remains one of the most useful mutations during the early and mid-game.
Frozen Mutation
Frozen also provides a 2x multiplier, matching Diamond in terms of overall profit.
The easiest way to obtain Frozen fish is during:
- Frozen Weather Event
Whenever this weather appears, it’s worth spending time fishing since Frozen mutations become significantly more common.
Cat Mutation
Cat is one of the stronger mutations currently available, increasing both earnings and sale value by 2.5x.
You have the highest chance of obtaining it during:
- Cat Weather Event
- Premium Cat Weather Event
Since its multiplier is noticeably higher than Gold and Diamond, Cat mutations are excellent additions to any profitable base.
Bloody Mutation
Bloody offers an impressive 3x multiplier, making it one of the highest-value mutations obtainable through weather events.
The best way to farm Bloody fish is during:
- Bloodmoon Weather Event
You can also apply this mutation using the Mutation Machine after unlocking it through Rebirth progression.
Molten Mutation
Molten currently provides the highest multiplier in the game, increasing both passive income and selling value by 4x.
Players can obtain Molten fish through:
- Rainbow Weather Event
- Mutation Machine
Because of its massive bonus, Molten is considered one of the most valuable mutations to collect if you’re aiming to maximize your long-term earnings.

Which Mutation Is the Best?

Taking advantage of weather events and unlocking the Mutation Machine as early as possible will greatly improve your chances of building a base filled with high-value mutated fish.
