Anomalous Mutation Fisch Guide, How to Obtain

Getting cash fast in Fisch usually comes down to upgrading gear, targeting rare fish, or waiting for limited events. But there’s another method players often overlook, and it’s one of the strongest passive money boosters in the game — the Anomalous Mutation. Also check out Fisch Codes for more rewards!

This effect can turn a normal catch into something worth several times the original value, and the best part is that anyone can start using it without advanced gear or rare materials. Below is a full guide explaining how the mutation works, what makes it valuable, and how to activate it consistently.


What Makes the Anomalous Mutation Important

The Anomalous Mutation is one of the best money-focused effects in Fisch. When it activates, the value of the fish increases by over five times, making it one of the most profitable perks available. For players grinding currency, this mutation can outperform multiple normal catches by turning one fish into a massive payout. Visual changes also make it easy to recognize. An anomalous fish is:

  • Pale red in color
  • Surrounded by shifting particles that fade between white and dark red
  • Brighter and more saturated depending on the fish’s size

If you see a glowing red fish, you already know it’s valuable before checking stats.

How to Trigger the Mutation

Unlike some mechanics in Fisch, the Anomalous Mutation doesn’t depend on location, weather, or biome. The only requirement is using the Anomalous Enchantment on your rod. Once equipped, every cast comes with:

  • 20% chance to apply the mutation to the next fish

The chance isn’t guaranteed, but it’s high enough that with fast fishing and a steady pace, anomalous catches start appearing often. Better news — the enchantment materials are not rare. Most players can unlock and use this perk shortly after reaching basic enchanting.

Best Way to Use the Anomalous Mutation

Since the perk multiplies value, it’s most effective when used on:

  • Heavy species
  • High base price fish
  • Targets caught with rods focusing on luck or catch speed

Combining rod speed with the enchant makes the 20% chance apply more frequently over time. The more casts you make per minute, the more anomalous fish you’ll end up collecting. Many late-game players pair the enchant with rods that increase weight or luck to push value even higher.


If you’re looking for a reliable way to make more currency in Fisch without farming rare events or traveling between islands, the Anomalous Mutation is one of the most efficient systems available. It scales well, works anywhere, and rewards fast fishing with massive payouts.

Once you get into a rhythm and keep the enchant active, your earnings rise naturally while also giving you unique glowing catches. For players grinding toward expensive gear or rare cosmetics, this mutation becomes one of the most useful tools in the entire game.
