Walk into almost any pet store, and you’ll likely see rows of betta fish in tiny plastic cups, sitting on shelves with barely enough water to move. While this method may be convenient for retailers, it’s not ideal for the fish. Bettas are intelligent, active creatures that thrive in well-maintained environments with ample space, filtration, and enrichment.
Fortunately, cups are not the only way to display bettas in stores. More retailers are recognizing the importance of humane fish care and adopting better display methods that promote fish health and customer engagement.
Why Cup Displays Are Problematic

Betta fish are often displayed in small plastic cups at pet stores, a practice that is convenient for retailers but harmful to the fish. While bettas can survive in small amounts of water for short periods, this setup leads to numerous health and welfare concerns.
1. Limited Space Causes Stress and Poor Health
Bettas are active fish that need room to swim and explore. Keeping them in tiny cups restricts their movement, leading to stress and lethargy. Prolonged confinement in such small spaces can weaken their immune system, making them more susceptible to disease.
2. Poor Water Quality Leads to Disease
In small cups, waste quickly accumulates, creating toxic conditions. Ammonia and bacteria build up rapidly without proper filtration, leading to ammonia poisoning, fin rot, and other infections. Frequent but inconsistent water changes in stores can also cause sudden shifts in water conditions, further stressing the fish.
3. Lack of Heating Causes Temperature Fluctuations
Bettas are tropical fish that require a stable water temperature of around 78-80°F. Store environments are often too cold, and tiny cups cannot regulate temperature. Exposure to fluctuating or low temperatures weakens their immune system and slows their metabolism.
4. Increased Risk of Fin Damage and Stress
The cramped conditions of a cup often lead to bettas resting against the plastic or on the bottom, which can cause their delicate fins to tear. Additionally, being surrounded by other bettas in close proximity without proper barriers can lead to constant stress, as they instinctively flare and posture in a defensive manner.
5. Misleading Care Expectations for Buyers
Displaying bettas in small cups sends the wrong message to customers—that bettas can thrive in tiny, unfiltered containers. Many buyers assume they don’t need a proper tank, leading to continued improper care after purchase. Stores that use better display methods help educate customers on the real needs of these fish.
By understanding these issues, customers can make more informed choices and advocate for humane alternatives in pet stores.
Alternative Display Methods
Many stores continue to display betta fish in small plastic cups, but there are far better ways to showcase these vibrant, intelligent creatures while ensuring their well-being. Here are some humane and visually appealing alternatives that pet stores can adopt.
1. Divided Aquariums with Filtration
Instead of isolating bettas in tiny, stagnant containers, stores can use larger tanks with dividers to house multiple bettas. This setup allows each fish space while benefiting from shared filtration and heating. It also provides a more natural swimming area, reducing stress and promoting overall health.

2. Community Tanks with Compatible Fish
While bettas are territorial, they can coexist with particular tank mates in a well-maintained, spacious community aquarium. Some stores successfully keep bettas in display tanks with peaceful species like snails, shrimp, or non-nipping schooling fish. This setup allows customers to see bettas in a more realistic home environment while ensuring they remain stress-free.
3. Planted Nano Tanks
A small but enriched environment with live plants, hiding spots, and gentle filtration is a great way to display bettas. These setups look more appealing to customers and promote the fish’s natural behaviors, such as exploring, resting on plant leaves, and even bubble nesting. A well-decorated nano tank highlights the beauty and personality of each betta while keeping them healthy.

4. Shelf Displays with Individual Small Tanks
Instead of stacking rows of bettas in plastic cups, stores can use neatly arranged, small individual tanks (1-2 gallons) with filtration and heating. This setup allows customers to observe the fish in an environment that mirrors a proper home setup, making them more likely to invest in suitable care. Some stores even add LED lighting to enhance the colors of the fish, creating an attractive display.
5. Interactive Adoption Areas
Rather than treating bettas as impulse purchases, stores can create interactive sections where customers learn about proper betta care before buying. This could include digital screens with care guides, informational signage, or staff educating potential owners on tank size, water parameters, and diet. By prioritizing education, stores can ensure bettas go to homes properly prepared for their needs.
These alternative display methods not only improve the lives of bettas in stores but also create a more engaging and responsible shopping experience for customers. Implementing these changes can set a higher standard in the pet industry, promoting ethical fishkeeping and long-term fish health.
Encouraging Support for Stores That Prioritize Fish Well-Being
As consumers, we can drive change by supporting pet stores prioritizing betta fish's well-being. Here are a few ways to recognize and advocate for ethical stores while discouraging harmful practices.
1. Choose to Buy from Stores with Better Practices
Look for pet stores that display bettas in filtered, heated tanks rather than tiny cups.
Prioritize independent pet stores or aquatic specialty shops that emphasize proper fish care.
If a store uses humane display methods, let them know you appreciate it—positive feedback encourages them to continue ethical practices.
2. Speak Up and Advocate for Better Conditions
If a store displays bettas in poor conditions, politely ask to speak with a manager and express concern.
Suggest alternative display methods (such as divided tanks or nano setups) and explain why they’re better for fish health.
Leave reviews or contact corporate offices of major pet chains to encourage policy changes.
3. Educate Others About Betta Fish Care
Many people don’t realize that bettas need at least a 5-gallon tank, a heater, and filtration. Sharing this information can help shift consumer demand toward ethical pet stores.
Social media spreads awareness about humane betta care and responsible pet store choices.
Encourage friends and family to support stores that prioritize fish well-being.
4. Support Businesses That Promote Responsible Fishkeeping
Some pet stores provide educational resources, such as care guides or workshops, to help customers understand the needs of betta fish. These are the stores worth supporting.
If a store refuses to improve its betta displays despite concerns, consider purchasing from ethical online aquatic retailers instead.
By choosing where we shop and advocating for better care, we can help improve the conditions of betta fish in the pet trade and encourage more stores to adopt humane display practices. Every small effort makes a big difference in the lives of these beautiful fish.
