- Sell at the marketplace take your fish and treasure to Mr. Wiwok's store and exchange them for gems.
Building your aquarium and collecting income
Step
The tutorial walks you through placing a wall, floor, and roof in that order, then has you set up your first tank. Once the tank is built, you add fish to it through the MANAGE menu. Fish sitting in tanks generate money every second automatically, which piles up at the ATM until you withdraw it. The ATM has a cap on how much it holds, and you raise that cap at the Gear Shop.
- Build walls, floor, and roof follow the tutorial prompts to lay each piece in sequence.
- Set up your first tank you can only add fish after the tank itself is placed.
- Open MANAGE to stock the tank select the fish from your inventory inside that menu.
- Visit the ATM to collect money builds up over time.
- Upgrade the ATM limit at the Gear Shop.
The three dock shops and what each one does
Table
All three shops sit on the dock. The tutorial introduces them after you complete all 14 steps.
| Marketplace | where you sell caught fish and found treasures in exchange for gems. |
| Gear Shop | where you buy equipment upgrades and raise the ATM withdrawal limit. |
| Coach | an NPC who improves your diving skills, including breath, swim speed, and luck. |
Upgrades that open up deeper water
Tips
Three stats can be upgraded: breath, swim speed, and luck. Raising breath extends how long you can stay underwater. Swim speed cuts down travel time. Luck raises your chances of running into rarer creatures. The biomes you can reach include coral reefs, kelp forests, shipwreck graveyards, and bioluminescent abysses.
- Breath upgrades extend how long you can stay underwater.
- Swim speed upgrades reduce travel time.
- Luck upgrades raise the chance of encountering rarer creatures.
Weather, time of day, and rare fish
Check
The game runs a dynamic weather system alongside a day and night cycle. Some fish appear only at night, others only during the day, and certain species are tied to specific weather events. Tracking your index lets you spot the gaps.
- Check whether it is day or night before you dive, since some fish only appear during one of the two.
- Watch the weather and head out when conditions change, because rare fish can be tied to specific weather states.
- Open your fish index to see which species you are still missing.
Redeem codes
WarnThe developers release gift codes that can be redeemed inside the game for items or currency. Each code has an expiry date and can only be used once per account.

Common questions
FAQCan I build an aquarium without spending Robux?
Yes. Selling fish and treasure at the marketplace earns gems, and fish in your tanks generate coins passively that you collect at the ATM. Completing the tutorial also hands you 300 coins.
Why am I not seeing any rare fish?
Rare fish only appear under specific weather conditions or at particular times of day. Upgrading your luck stat through the Coach also raises the chance of encountering rarer species.
How do I stop having to collect from the ATM so often?
Visit the Gear Shop on the dock and purchase ATM limit upgrades to raise that cap.
What happens after the tutorial ends?
The game displays descriptions of all three dock shops — the Marketplace, Gear Shop, and Coach — so you know what each one offers. The fish index tracks your progress.
