Mutated fish are the fastest way to grow your money in Claw Fishing. They sell for more and, once placed in your aquarium, they earn more per second than their normal versions. Right now the game has three mutations, and each one raises both the sale price and the passive income of the fish it affects.
Quick answer: Catch fish carrying the Silver, Gold, or Rainbow label to multiply their sale value and per-second earnings by 5x, 10x, and 15x. They spawn randomly across every area of the ocean, so watch for the mutation text above a fish’s name and grab it with your claw.
All three Claw Fishing mutations and their multipliers
Every mutation applies a flat multiplier to both the fish’s sell price and its income rate in the aquarium. A Gold fish, for example, sells for ten times what the same fish would sell for without the mutation and also generates ten times the money per second once equipped.
| Mutation | Multiplier | How to spot it |
|---|---|---|
| Silver | 5x sale value and earning rate | “Silver” text above the name; the fish looks fully silver. |
| Gold | 10x sale value and earning rate | “Gold” text above the name; a glowing yellow aura surrounds the fish. |
| Rainbow | 15x sale value and earning rate | “Rainbow” text above the name; the fish has a shifting, dynamic appearance. |
How mutated fish spawn
Mutated fish appear on their own with a random chance in every part of the map. There are no weather events tied to mutations, so you do not need to trigger anything special. You can find a mutated catch even while staying behind the buoy line, which keeps you safe from tsunami waves.
The only skill involved is recognizing one before you lower your claw. Each mutated fish carries its mutation name as text above the standard name and has a distinct look, so a quick scan of the water tells you whether a fish is worth targeting.
How to catch a mutated fish
Which mutation is the best to chase
Rainbow is the strongest mutation. Its 15x multiplier is the highest in the game, which also makes it the rarest to find. Rainbow fish have the lowest natural spawn chance of the three, so they take the most patience to hunt.
To improve your odds of finding one, push toward the farthest area of the ocean, where the rarest fish appear. Playing during the Admin Abuse Event is another strong way to encounter Rainbow-mutated catches. If you are still building up, a steady stream of Silver and Gold fish will fund the boat, claw, crane, and aquarium upgrades that let you reach those distant waters safely.
Because values and spawn behavior can shift as the game updates, confirm the current multipliers and any new event details in the live game before committing a long farming session to one target.
