What should you do next?
An editorial priority guide for training, hatching, earning, and upgrades. Species rankings await comparable game data.

Use priorities for decisions, not unsupported species grades
This hub helps choose the next action in the collection loop. It does not present a numerical fish tier list: comparable current species, size, mutation, and income values have not been established for this version. The relevant priority changes when the obstacle changes.
Which problem should come first?
| Target | Priority | Reason and success signal |
|---|---|---|
| Unfinished hatch | Complete the missing tank or hatch step. | Another pickup is not yet a collection result; success means a fish you can inspect. |
| Unfamiliar path | Practice a recognizable return route. | Navigation errors can resemble a speed problem; success means knowing the way back. |
| Movement limit | Train and repeat a comparable route. | The same task before and after training tells you whether movement improved. |
| Money requirement | Measure collection earnings and budget the relevant upgrade. | A purchase plan needs its current price, remaining amount, and a clear purpose. |
Set a stopping point for the next test
Pick one action and one observable result before starting. If the result resolves the block, choose the next goal. If it does not, inspect what actually happened rather than automatically moving to a more expensive upgrade. A rare collection goal can remain a separate experiment while a manageable route supports your baseline.
