All Mutations and Multipliers Net a Fish Mutations Guide!
Mutations are one of the best ways to increase your earnings in Net a Fish on Roblox. Unlike normal fish, mutated variants have higher values and can generate more money over time. Depending on the mutation, a fish can earn up to 3x more than its regular version, making them valuable catches for players who want to progress faster.
There are currently seven mutations available in the game, each offering a different multiplier. You can obtain them by catching mutated fish in the river or fusing duplicate fish through the game’s fusion system. Here is a complete guide to all Net a Fish mutations, their multipliers, and how to get them.
How to Get Mutated Fish in Net a Fish
There are two main ways to obtain mutated fish in Net a Fish. The first method is to catch them directly from the river, while the second involves combining duplicate fish through the fusion system.
If you want to increase your chances of finding rare mutations, there are several upgrades, events, and baits that can help you.
1. Purchase Mutation Magnet Upgrades

The Mutation Magnet is one of the most useful upgrades for players hunting mutated fish. You can find it by opening the Upgrades menu, selecting Fishing, and scrolling down until you see the Mutation Magnet option.
Purchase the upgrade and continue improving it whenever you have enough resources. Higher upgrade levels will increase your chances of catching mutated fish, making it easier to find valuable variants while fishing.
2. Participate in Special Fishing Events
Certain limited-time events can improve your chances of finding mutated fish. Three events worth looking out for are:
- Wave Rush: An event that can increase your opportunities to catch mutated fish.
- Lucky Tide: Another special event that improves your chances of finding valuable fish.
- Shimmer Surge: A useful event for players who want to collect more mutated variants.
Try to spend more time fishing whenever these events become available. Taking advantage of their bonuses can help you collect mutations faster than fishing during normal gameplay.
3. Use Special Baits
Baits are another important factor when hunting for mutated fish. Some special options provide better chances of finding mutated variants, making them useful for players who want to improve their fishing results.
Here are three baits you should consider using:
- Glitter Lure
- Starlight Worm
- Phoenix Feather
You can unlock these baits through the Bait Shop after completing certain Rebirth requirements. If you have already unlocked them, consider using them whenever you are trying to catch rare mutations.
4. Fuse Duplicate Fish
Besides catching mutated fish directly, you can also create them by combining duplicate fish through the fusion system. This method is useful when you have collected too many fish of the same mutation and want to upgrade them into a rarer variant.
The fusion system requires different numbers of fish depending on the mutation you want to obtain.
Here is the complete fusion progression:
- 10 Normal Fish: Fuse them to get 1 Shiny Fish.
- 8 Shiny Fish: Fuse them to get 1 Gold Fish.
- 6 Gold Fish: Fuse them to get 1 Crystal Fish.
- 4 Crystal Fish: Fuse them to get 1 Glitched Fish.
- 3 Glitched Fish: Fuse them to get 1 Rainbow Fish.
- 2 Rainbow Fish: Fuse them to get 1 Starlit Fish.
Keep collecting duplicate fish if you want to use this method. Although reaching the higher mutation levels requires several fish, fusion provides another way to obtain valuable variants without relying entirely on random catches.
All Net a Fish Mutations and Their Multipliers
According to the Mini-Games Update, Net a Fish currently has seven mutations. Each mutation increases the fish’s earning rate and selling value, but the multiplier becomes higher as you progress toward rarer variants.
Here is the complete list of mutations and their respective multipliers:
1. Shiny Mutation – 1.15x
Shiny is the first mutation you can obtain through the fusion system. It provides a 1.15x multiplier, increasing both the fish’s earning rate and selling value compared to its normal version. While the bonus is relatively small, it is a good starting point for players who are beginning to collect mutated fish.
2. Gold Mutation – 1.25x
Gold is the next mutation after Shiny and offers a 1.25x multiplier. This variant provides a slightly higher return, making it a better option when you want to increase your earnings. You can obtain it by fusing eight Shiny Fish together.
3. Crystal Mutation – 1.35x
Crystal offers a 1.35x multiplier, giving you another improvement in earning potential. It is the third mutation in the fusion progression and requires six Gold Fish to create. Players looking to upgrade their collection should consider working toward this variant.
4. Glitched Mutation – 1.5x
Glitched fish provide a 1.5x multiplier, making them more valuable than the previous mutations. Both their earning rate and selling value receive a noticeable boost. To obtain this mutation through fusion, you need four Crystal Fish.
5. Rainbow Mutation – 2x
Rainbow is one of the more valuable mutations in Net a Fish, offering a full 2x multiplier. This means your fish can generate twice the earnings of its normal version. You can create one Rainbow Fish by fusing three Glitched Fish.
6. Starlit Mutation – 2.5x
Starlit is currently the highest mutation in the regular fusion progression. It provides a 2.5x multiplier, making it an excellent choice for players who want to maximize their fishing income. To obtain one, you need to fuse two Rainbow Fish together.
7. Haunted Mutation – 3x
Haunted is the highest-value mutation listed in Net a Fish, offering an impressive 3x multiplier for both earnings and selling value. However, this mutation is currently unobtainable. Players who already have Haunted fish can benefit from its high value, but you cannot currently farm it through the normal fishing or fusion methods.
Which Net a Fish Mutation Should You Aim For?
Not every mutation provides the same benefits, so knowing which variants to prioritize can help you manage your fish collection more effectively.
If you are still progressing through the game, Shiny, Gold, and Crystal are good starting points because they are easier to obtain through the fusion system.
However, if your goal is to maximize earnings, you should eventually aim for Rainbow and Starlit fish. Their 2x and 2.5x multipliers provide much better returns than the lower-tier mutations.
Here is a quick breakdown of the mutations worth targeting:
- Early Progression: Shiny and Gold are useful starting mutations.
- Mid Progression: Crystal and Glitched offer better earning bonuses.
- High Progression: Rainbow and Starlit are the best obtainable mutations for increasing your income.
- Highest Multiplier: Haunted offers 3x, but it is currently unobtainable.
Mutations are an important part of making money in Net a Fish because they increase both fish earnings and selling values. There are seven mutations listed in the game, starting with Shiny at 1.15x and going all the way up to Haunted at 3x.
You can obtain mutated fish by catching them in the river, using special baits and upgrades, participating in fishing events, or fusing duplicate fish. If you want to maximize your earnings, focus on collecting Rainbow and Starlit fish while keeping an eye out for future opportunities to obtain the Haunted mutation.
