Steal Fish Eggs Swim Training: How to Increase Swim Speed

To increase your swim speed in Steal Fish Eggs, train on the endless pool. The game's official How to Play instructions list two distinct endless-pool actions: "🌊 Upgrade your endless pool and base" and "🫧 Train on the endless pool to gain swim Speed." This confirms training on the endless pool is the intended mechanic for raising swim speed — and that it's a separate activity from upgrading the pool itself.

How training works

Find the small swimming pool near your base — this is the endless pool training station. In one observed session, the training station worked like a treadmill, and unlocking it cost 1,000 in-game cash (that was that session's price, so expect costs to vary). In the observed session the player reached the pool/treadmill and began training; the exact on-screen start prompt was not captured, so look for the training prompt at the pool and follow it.

During a workout, scrolling prompts such as Watch videos can appear; in the observed session the player scrolled through them and the session then ended with a speed gain. Whether this fill appears in every session is not documented.

Confirming your gains

The game displays your current swim speed as a number, and zones show the speed they require, so you can check before and after a session. In one session a player saw a zone requiring 1,000 speed while they had 10; after training at the pool, their speed read 2,600 and they could complete the steal. Compare your displayed speed number before and after a training session — that's the clearest check that the training worked.

Training has a concrete pass/fail test: each zone lists a recommended swim speed, and if you're too slow, the zone boss can eventually catch you. Getting caught ragdolls your character, and if you're carrying an egg at the time, you lose it. So if a zone steal failed because you got caught, train up and retry it.

Training conditions and limits

• Whether training gains persist across sessions, and whether there is a cap on swim speed, are not documented — observe your own results.
• Treat claims of code or promotion training shortcuts skeptically; check the codes page for what is currently confirmed before trusting any shortcut claim.

Training vs. upgrading the pool

These are two different actions at the endless pool, and both raise your swim speed:

• Train — a workout session at the pool that increases your swim speed (this page).
• Upgrade — buying improvements to the pool itself, which also raises your speed. Costs and tiers are covered in the endless pool upgrades guide.
• Trails — purchases that also boost how fast you move through the water.

In the session above, the player trained at the treadmill for an initial gain, then separately upgraded the pool and saw their speed climb much further — so don't stop at training if you're still short of a zone's requirement.

Next step: complete a training session, swim to confirm you've gotten faster, then use the progression guide to decide whether movement or tank capacity is your next bottleneck.
