Pet Store Tycoon: A Complete Guide to Fish Tanks & Aquatic Pets

Mastering Aquatic Pets in Pet Store Tycoon

In Pet Store Tycoon on Roblox, developed by Already Arrived Studios, fish are often the first major category of animals you will manage. Unlike the floor-based pets that roam enclosures, aquatic pets require a higher level of daily maintenance and specific infrastructure. Understanding the fish tank ecosystem is essential for turning a profit and scaling your store from a small shop into a bustling pet empire.

Whether you are just finishing your opening day tutorial or looking to optimize your store for higher revenue, managing your aquariums effectively is the key to success. This guide covers everything from sourcing your first stock to advanced tips on maintenance and passive income generation.

How to Acquire and Unlock Fish

Before you can display fish, you must acquire them through the in-game order system. Fish are not bought individually as specific species; instead, you purchase "packs" that yield a random assortment of aquatic life.

1. Access the Order Terminal: Locate your shop counter or the dedicated ordering station. Interact with it using your interaction key (F on keyboard or the on-screen prompt).
2. Purchase a Fish Pack: Navigate to the pet order catalog and select the Fish option. A standard pack typically costs $100 in-game cash.
3. Unbox Your Pack: Once purchased, open the container to reveal three random fish. You may roll common species like Goldfish, Betta, or Discus, or potentially pull higher-tier rare or epic fish.
4. Manage Inventory: After inspecting your pull, click "Keep" to move the fish into your holding inventory. If you are unsatisfied or have no space, you can discard them.
5. Assign to Tanks: Walk over to a placed aquarium and add the fish to the display so they are visible to your customers.

This is an excellent way to acquire rare or legendary fish, such as the Giant Oarfish, early in the game without spending your hard-earned cash.

Setting Up and Organizing Your Aquariums

Fish tanks are distinct from other store displays. You cannot place fish on standard floor shelves; they require specialized aquatic enclosures. Proper placement is not just about aesthetics—it is a functional requirement for sales.

Choosing and Placing Tanks

When you are ready to expand, access the shop or build interface. Basic tanks usually cost between $100 and $200. Always keep an eye on your floor plan capacity. Standard starter tanks can hold three to four fish comfortably.

When placing your tanks:

• Visibility: Place aquariums near the store entrance or high-traffic areas. Customers are more likely to browse displays they encounter immediately upon entering.
• Rotation: Use the rotation tool (Q on keyboard or your controller prompt) to align tanks against walls or in islands to maximize floor space.
• Backstock Management: If your tanks are full, any fish you unbox will remain in your backstock. Plan your expansion by building more tanks as soon as your revenue allows to ensure you aren't leaving potential profits sitting in storage.

Essential Aquatic Maintenance Routine

Neglecting your aquariums is the fastest way to lose customers. In Pet Store Tycoon, fish care is a recurring task that must be performed throughout the business day. If a tank looks neglected, shoppers will pass it by, meaning you lose the sale.

There are three primary maintenance tasks you must perform:

• Feeding: Approach an active aquarium and press the feed prompt. You will see food flakes drop into the water. This clears the hunger exclamation marks that appear over the tank.
• Cleaning Glass: Over time, algae and smudges will obscure the view. Interact with the tank to wipe down the glass. A clean tank is essential for customer satisfaction.
• Replacing Filters: Every aquarium has a built-in filtration gauge. When this gauge runs low or dirty, the water quality drops. Interact with the system to install a new filter cartridge.

Warning

Don't Ignore the Exclamation Marks: If you see an exclamation mark over a tank, it indicates a specific need (hunger, dirty water, or dirty glass). Failing to address these will result in customers ignoring your fish entirely. Make a habit of doing a "sweep" of your store every few minutes to check these indicators.

Selling Fish vs. Passive Income

One of the most important strategic decisions in Pet Store Tycoon is how you utilize your rare and legendary fish. While common fish are straightforward inventory for retail sales, higher-tier species offer a choice.

By default, legendary and exotic pets are often set to "Not for Sale" when placed in an aquarium. This allows them to act as passive income generators, earning you money simply by being in your store. However, if you are in immediate need of capital, you can open the aquarium's settings panel and toggle the "For Sale" switch. This converts the fish into a high-value retail item that will be sold to the next interested customer.

Stocking Aquatic Care Supplies

While selling fish is your primary source of income, you should not overlook the secondary market: aquatic supplies. Many customers who browse your fish tanks will also look for the items needed to care for them at home. If your store does not carry these items, you are missing out on significant revenue.

Ensure your store is stocked with:

• Fish Flakes: The most basic food item, usually sold from counter racks.
• Tropical Fish Pellets: A mid-tier food option that yields a higher profit margin.
• Water Conditioner: A critical chemical product that customers expect to find in a well-stocked pet store.

Always order these supplies from your shop terminal well before opening. Carry the boxes to your store and stock them on your display shelves. A store that sells both the fish and the supplies to care for them is far more efficient than one that only offers the pets themselves.

Troubleshooting Common Issues

Even experienced managers run into issues where sales seem to stall. If you find that customers are walking through your store without stopping at your fish tanks, check the following checklist to identify the problem.

• [ ] Are the tanks clean? Check for dirty glass or low filter gauges.
• [ ] Is the fish fed? Ensure there are no hunger indicators.
• [ ] Is a register open? Customers cannot complete their purchase if there is no cashier or open register to process the transaction.
• [ ] Are the fish for sale? If you have rare fish, check the settings panel to ensure they aren't accidentally locked to "Not for Sale."
• [ ] Is your store open? Ensure your store sign is set to "Open" and not "Closed."

FAQ

Why are customers not buying my fish?

Shoppers generally ignore fish if the aquarium is neglected. Ensure the fish are fed, the glass is wiped clean, and the filter is replaced. Additionally, verify that you have an open, manned register so customers can finalize their purchase.

Can fish die if I forget to feed them?

No, pets in Pet Store Tycoon do not permanently die from lack of care. However, neglected fish will have lower happiness meters and show warning indicators, which will actively discourage shoppers from browsing that tank.

How do I get more tank space?

You can purchase additional tanks from the build menu for $100–$200. If you run out of floor space, interact with the store expansion pad to unlock the adjacent building lot, which typically starts at $300.
