Key Considerations Before Buying a 5 Gallon Betta Tank

Funny image of 5 gallon betta tank contest

Before purchasing a new 5 gallon betta fish tank, it’s important to consider several key factors to ensure you’re providing the best environment for your betta fish.

Here are some considerations:

1. Tank Material

Decide whether you prefer glass or acrylic. Glass is more scratch-resistant but heavier, while acrylic is lighter and can offer more clarity but is easier to scratch.

    • Glass Tanks: These are the traditional choice for many aquarium enthusiasts. Glass offers unparalleled clarity, making it a superb choice to showcase the radiant hues of your betta. Furthermore, glass is resistant to scratches, ensuring a clear view for years.

    • Acrylic Tanks: These are modern alternatives that boast being lighter and more impact-resistant than glass. Acrylic tanks can be molded into various shapes, allowing for creative tank designs. However, they can scratch more easily than glass, so handle them with care.

2. Shape & Design

    • Size & Shape: While 5 gallons is a suitable size for a betta, the shape of the tank is also important. Betta fish prefer wider tanks over taller ones as they need surface area to breathe. Bettas are surface swimmers and frequently come up for air, owing to their unique labyrinth organ. Thus, a tank that prioritizes horizontal space over depth is ideal. A broad, shallow tank design mimics their natural habitat, allowing them ample space to swim side to side and easily access the surface
    • Safety First: Bettas have delicate fins that can easily tear. Ensure the tank’s internal design or decorations have no sharp edges. If the betta fish tank comes with pre-installed structures, make sure they are smooth and betta-safe.
    • A Secure Lid is a Must: Bettas are known to be occasional jumpers, possibly due to their natural instinct to move between puddles in their wild habitat. A tight-fitting lid is non-negotiable to prevent unwanted escapes and ensure your fish’s safety.

      The lid should be secure to prevent your betta from jumping out, but also easy to open for feeding and maintenance. A lid with built-in lighting or feeding ports can be a plus.

3. Your Budget

Quality should always be a priority over price. Remember that a fish tank is a long-term investment. It’s not just about the initial set-up cost, but also about ensuring a healthy and sustainable environment for your betta over the years.

    • Initial Purchase Price: The upfront cost of the tank itself can vary widely based on the brand, material, and included features. Basic tanks might be more affordable, but remember that you may need to purchase essential accessories separately.

    • Quality vs. Cost: Investing in a higher-quality tank can be more cost-effective in the long run. Cheaper tanks might need more frequent replacements or repairs, which could add up over time.

    • Included Accessories: Some tanks come as part of a kit, including filters, heaters, and lighting. While this can be a cost-saving option, ensure that these included items are suitable for bettas and of good quality. Sometimes, buying items separately can be more cost-effective in ensuring quality and suitability.

By considering these budget factors, you’ll be better prepared to make a cost-effective decision that balances initial expenses with long-term value and the ongoing costs of maintaining a healthy and enriching environment for your betta fish.

4. Popular Brands & Quality

With the rising popularity of betta fish, many brands offer ‘betta-specific’ tanks. While these can be suitable, always research the brand’s reputation. A well-constructed betta fish tank from a reputable manufacturer ensures durability and safety for your aquatic friend.

Essential Equipment For Betta Care

Aquarium Heater

Betta fish thrive in warm water, ideally between 78-82°F (25-28°C). Ensure the tank can accommodate a reliable aquarium heater to maintain a consistent temperature.

A consistent water temperature is vital for the well-being of betta fish. A reliable and adjustable aquarium heater ensures these conditions are met, promoting The betta’s health and longevity.

Gentle Filtration System

Bettas require clean, stable water conditions. A gentle filtration system is important as bettas do not do well with strong currents, which can stress your betta. Look for a filter that is adjustable or betta-friendly, Select a filter that effectively and gently purifies the water current,  biological or chemical filtration will do the job!

LED Lighting

Consider the lighting needs, especially if you plan to have live plants. Adequate lighting is essential for plant growth and can also highlight the colors of your betta fish, Opt for adjustable LED lights that can replicate a natural day-night cycle, benefiting both plant and fish health.

Aquarium Thermometer

Regularly monitor the water temperature with an accurate thermometer to ensure that the heater is functioning optimally and maintaining the desired temperature range.


A substrate, whether it’s fine gravel or sand, provides a foundation for your betta tank. It serves both aesthetic purposes and aids in beneficial bacteria cultivation.

Aquascaping, Decorations and Shelter

Bettas need places to hide and rest. Silk or live plants, smooth rocks, and caves are great for providing shelter and stimulation. Avoid sharp decorations that can tear their fins.

Plants, whether silk or live, provide enrichment and additional shelter for your betta. They also assist in maintaining water quality by absorbing nitrates

Water Test Kit

Bettas require specific water parameters, including pH levels, hardness, and ammonia/nitrite/nitrate levels. Make sure you have the means to test and adjust these as needed.

Regularly monitor the water parameters using a comprehensive test kit. Checking for levels of ammonia, nitrites, nitrates, and pH ensures the water remains safe for your betta.

Nutritious Diet

Offer a varied and balanced diet to your betta. High-quality pellets, combined with occasional treats of frozen or live foods, support optimal health and coloration.

🏆 Pro Tip: Consider how easy the tank is to clean Regular maintenance is crucial for Betta’s health.

Equipped with this list, you’re prepared to offer your betta fish an environment that supports their health, well-being, and natural behaviors. Proper care and investment in the right equipment ensure a thriving and vibrant aquatic companion.

FAQs about 5 Gallon Betta Tanks

Q: Why is a 5 gallon tank recommended for bettas?

A: A 5 gallon tank provides ample space for a betta to swim, explore, and display natural behaviors. It also allows for a more stable water environment compared to smaller containers, helping prevent rapid fluctuations in water parameters.

Q: Can I keep my betta in a bowl or a vase?

A: While bettas can survive in small containers, it doesn’t mean it’s an ideal environment. Bowls and vases often lack the necessary space, heating, and filtration to remove waste and uneaten fish food, which can stress the fish and shorten its lifespan.

Q: Is it essential to have a lid for my betta tank?

A: Yes. Bettas are known to jump, and a lid prevents potential escapes. Additionally, a lid reduces evaporation and helps maintain a stable water temperature.

Q: Glass or acrylic – which tank material is better?

A: Both have their merits. Glass offers superior clarity and is scratch-resistant, but it’s heavier. Acrylic is lighter and can be molded into various shapes but can scratch more easily. Your choice should be based on your preferences and handling capabilities.

Q: Do bettas prefer a particular tank shape?

A: Bettas prefer horizontal swimming space, so longer, wider tanks are more suitable than tall, narrow ones.

Q: I've seen tanks with LED lighting. Is that safe for bettas?

A: Yes, LED lighting is safe and energy-efficient. However, like all fish, bettas need a day-night cycle. If your tank has lighting, ensure it’s not left on constantly to give your betta some rest.

Q: Can I house more than one betta in a 5 gallon tank?

A: Generally, it’s not recommended to place more than one betta in the same tank. Male bettas are territorial and will fight with other males.

While female bettas can sometimes be kept together in larger “sorority” tanks or with other tank mates. A 5 gallon tank does not provide enough space for multiple bettas to establish separate territories and feet for only a single betta fish.

Q: How often should I clean my 5 gallon betta tank?

A: It’s recommended to do partial water changes (about 20-30%) once a week. This will help maintain water quality. The tank itself should be cleaned as needed, but a complete water change and deep cleaning shouldn’t be frequent, as it can disrupt beneficial bacteria, consider using an external or internal filter as well.
