Steal Fish Eggs Progression Guide
Choose your next action from the bottleneck you can actually observe: a cash goal, two income setups, a known upgrade cost, or swim speed. This guide supplies the decision method—not invented prices, ranks, locations, or a universal best path.
Pick the problem you can measure
I am comparing two setups
Keep current and proposed rows separate. Unknown rates remain excluded instead of becoming zero.
Compare tank plans →I can see an upgrade cost
Use the cost only with current and proposed effective income in the same in-game currency and time unit.
Check cash payback →Movement is my bottleneck
The official description points to endless-pool training for swim speed. Exact gains and requirements are not documented here.
Review the confirmed scope →Recheck after every change
- Record the values and units currently visible.
- Change only the setup or upgrade you want to compare.
- Record the new visible values under the same conditions.
- Use the difference for a decision, and keep unknown effects outside the calculation.
An apparent improvement in one observation does not prove drop odds, hidden multipliers, offline income, or a permanent game formula.
Do not assume
The reviewed dataset does not currently establish a best upgrade order, universal tank capacity, upgrade costs or gains, rarity odds, egg refresh cycles, ideal locations, or a complete entity value list. See current publication coverage and the evidence methodology.
