BE A FISH BAIT — Mutations List

Updated September 2026

Mutation Types

Mutations alter fish appearance with glows, palettes, and particles. Each type carries a fixed value multiplier applied to sell and aquarium calculations. The Delulu update standardized eight mutation tiers; Radioactive at 8x is the current chase drop.

  • Gold — 1.5x | Diamond — 2x | Delulu — 2x | Champion — 3x
  • Plasma — 4x | Glitched — 5x | Molten — 6x | Radioactive — 8x

Stacking and Combos

Only Delulu and Champion can be added as secondary mutations on a fish that already has a primary mutation. The highest community-reported combo is Radioactive × Delulu × Champion. Yinyang and Voidspore auras boost mutation luck for farming these rolls.

Identification

Inspect fish before selling — mutation indicators include particle effects and UI tags on the catch popup. Screenshot unknown variants for Discord identification threads.

Stacking Rules

Typically one mutation per fish. Mutations stack multiplicatively with sell auras. Read the mutations explained guide for farming strategy.
