Use this mutation guide to separate public reports about mutated Fish from mechanics verified on the official Roblox page.
The current Roblox API and page description name Fish, Pools, Areas, Lakes, Upgrades, Wins, and Pets, but the August 22 official check does not publish a mutation roster or multiplier table. All Things How reports Gold (2x), Diamond (5x), Venom (10x), and Hole (20x); these are reported multiplier labels, not verified mechanics.
These are source-watch entries for players comparing a mutation guide or best mutation claim. Verify the label and effect in the current game before treating any report as a decision rule.
One accessible public report also mentions Poison and Black Hole weather, a claimed +10% bonus, and a four-minute duration. Those are reported weather claims only; no official Roblox event description or game-page field verified the duration, stacking, or effect.
Read the exact mutation label in-game, record the Fish and visible effect, and keep the observation dated. Do not call Hole the best mutation or apply a reported 2x, 5x, 10x, or 20x value until the current game shows it.
Keep Fish names and rarity labels separate from mutation reports.
