What players should assume before they chase mutation rolls
Public guide coverage now treats mutations as a live system with multiple names, multiplier tiers, and stacking rules. The site can satisfy that exact search intent today, but it still needs claim boundaries because the most detailed public tables are not creator-owned.
If you searched BE A FISH BAIT mutations, the safe practical answer is to treat mutations as a real part of aquarium optimization and late-session catch value. Public July 12 coverage now repeats the system strongly enough that a dedicated route is justified.
What should stay bounded is the exact number table. Public guides now claim a full set of mutation names and multipliers, but this page will not present every percentage or multiplier as official until a creator-owned source or stable in-game confirmation can be cited directly.
The current public consensus is narrower than a full database but clearer than a generic wiki blurb: guides checked on July 11 and July 12, 2026 are aligned on an eight-mutation lineup, with Radioactive as the strongest reported single multiplier and Delulu plus Champion treated as the special stackable pair.
That also answers the newer best mutation for money phrasing now showing up in video discovery: the safest public answer is still Radioactive for the highest reported single multiplier, while Delulu and Champion remain the reported stackable add-ons rather than separate replacements for the top money angle.
