BE A FISH BAIT — Fish Value Tier List
Updated July 2026
How Fish Are Ranked
Fish tier placement weighs aquarium per-minute income first, active sell price second, catch reliability third, and mutation ceiling fourth. A legendary that appears once per session ranks below a uncommon you chain every few minutes if the uncommon feeds slots faster.
S-Tier Fish
S-tier species come from mid and late zones with high base aquarium rates and strong mutation multipliers. They are farmable enough to fill multiple slots in one evening. Stock these exclusively once your rod accesses their zone.
A-Tier and B-Tier Fish
A-tier fish bridge early to mid game — good sells, acceptable aquarium rates, easy catches. B-tier fish are sell fodder or temporary tank filler until S-tier stock arrives. Never buy aquarium slots specifically for B-tier residents long term.
Zone Reference
Fish tie to map zones unlocked by rod tier. Cross-reference the map page and walkthrough for where each tier schools. Mutations bump any species one sub-tier minimum — a mutated B-tier can outearn a normal A-tier.
