Fish serve as the very first pets you manage in the 2026 version of Pet Store Tycoon on Roblox (developed by already arrived studios). Unlike standard floor animals that walk around enclosures, aquatic pets require dedicated aquariums, regular water maintenance, and matching shelf products to satisfy shoppers.
Whether you are finishing your opening day tutorial or expanding your storefront to fit larger species, here is everything you need to know about purchasing, stocking, and caring for fish.
How to Buy and Unlock Fish in Pet Store Tycoon
Acquiring fish requires using the in-game order terminal and purchasing pet packs with your store revenue:
- Access the Order Menu: Walk up to your shop counter or interact with the ordering station by pressing the interaction key (F on keyboard or the on-screen prompt).
- Purchase a Fish Pack: Select the Fish option from the pet order catalog. Basic fish packs cost $100 of in-game cash. (An Exotic pack is also visible in the shop menu for Robux).
- Open the Pack: Unbox the container to reveal three random fish. Gameplay footage shows common rolls such as the Goldfish, Betta, and Discus, alongside higher-tier rare or epic pulls.
- Choose to Keep or Discard: Inspect each rolled fish and click Keep to send them into your holding inventory.
- Assign Fish to a Tank: Walk over to an placed aquarium enclosure and add the fish so they appear on display for visitors.
Free Reward Packs
Players who like the game on Roblox, favorite the experience, and join the developer's community group can claim a free deluxe pet reward pack from the in-store claim station. Gameplay tests show this claimable reward can grant rare and legendary fish—such as the Giant Oarfish—without spending in-game cash.
Setting Up and Expanding Fish Tanks
Fish cannot be placed on standard shelves or floor enclosures; they require dedicated water tanks:
- Purchasing Enclosures: You can purchase basic fish tanks through the shop or build interface for $100 to $200 depending on the model.
- Tank Capacity: Standard starter tanks hold multiple fish (typically up to three or four per enclosure). If your tanks are full, unboxed fish remain queued outside or in backstock until extra tanks are built.
- Moving and Organizing: Press Q (or your controller's reposition prompt) while aiming at placed aquariums to rotate or relocate them around your floor plan. Placing aquariums near the entrance gives passing shoppers immediate visibility.
Essential Fish Care and Tank Maintenance
Customers will avoid purchasing fish if their living conditions drop. Managing aquatic displays requires three recurring tasks throughout the business day:
- Feeding Fish: Approach an active aquarium and press the feed prompt. Food flakes drop down from the top of the water, clearing hunger exclamation marks over the tank.
- Cleaning Tank Glass: Algae and smudges build up over time. Interact with dirty tanks to wipe down the glass pane so shoppers can view the animals inside.
- Replacing Water Filters: Aquariums feature a built-in filtration gauge. When the filter runs dirty, interact with the system to install a fresh cartridge and keep the water clean.
Selling Fish vs. Keeping Passive Earners
When opening your doors each morning, shoppers will browse your displays, select fish, and carry them to the checkout counter. However, certain rare species offer alternate benefits:
| Pet Category / Rarity | Typical Examples | Store Function | Earning Mechanics |
|---|---|---|---|
| Standard Fish | Goldfish, Betta, Discus | Active retail sale | Sold to visiting customers at register checkout |
| Legendary / Exotic Fish | Giant Oarfish | Passive income generator or luxury sale | Earns passive cash every hour the store remains open |
Legendary and exotic pets default to "Not for Sale" when placed inside an aquarium. Instead of leaving with a buyer, they produce steady passive revenue (such as $25/hour) as long as your shop is open. If you prefer a lump-sum profit, you can open the aquarium's individual settings panel and toggle the For Sale switch to on.
Stocking Aquatic Care Supplies for Maximum Profit
Shoppers frequently come looking for fish supplies alongside live animals. If your store lacks the corresponding items, customers may leave empty-handed:
- Fish Flakes: Basic food items sold from counter racks and small shelves.
- Tropical Fish Pellets: Mid-tier food containers that yield higher retail markups.
- Water Conditioner: Essential chemical bottles stocked on display shelves to maintain high customer satisfaction.
Order these boxes from your shop terminal, carry the delivered parcels inside, and stock your display racks before flipping your store sign to open.
Frequently Asked Questions (FAQ)
Why are customers not buying my fish?
Shoppers generally pass on fish if the aquarium is neglected. Ensure the fish are fed, wipe any dirty glass, and inspect the tank filter. Additionally, ensure you have an open, manned register so customers can complete their purchases.
How do I get more tank space?
You can buy additional tanks directly from the build menu for $100 to $200 in-game currency. If your floor plan is completely crowded, interact with the store expansion pad to unlock the adjacent building lot (initial expansions start at $300).
Can fish die if I forget to feed them?
In Pet Store Tycoon, pets do not permanently die from lack of care. However, neglected fish will show warning indicators, display lower happiness meters, and discourage shoppers from browsing that tank until the care routine is completed.
