How to test a mutation
A clean comparison changes one variable at a time. Record the species, size, displayed mutation, and income for both fish.
- Match the fish species.
- Match the size label.
- Remove temporary boosts from the comparison.
- Repeat after an update before treating the multiplier as permanent.
Best mutation
There is not enough confirmed public data to name a best mutation yet. The first useful ranking will compare real income gain and acquisition frequency, not color or visual rarity alone.
Why values can conflict
Screenshots may show different sizes, patches, or other upgrades. A number without context should not be copied into a multiplier table.
