How to Choose a Small Aquarium - Buying Guide
Whether you're new to fishkeeping or a seasoned aquascaper, the right small aquarium can make your setup easier and more enjoyable. Here's what to consider—from size and fish compatibility to materials and lighting.
Choose the Right Size Based on Your Space and Experience Level
Small aquariums seem easier, but size still matters! A slightly bigger tank can improve water quality, especially for beginners. Here's how to choose the right size for your needs.
For Beginners: Start With at Least a 10-Gallon Tank
If you’re new to fishkeeping, it’s best to go with a 10-gallon tank or larger. This gives your fish more space and provides better water stability, which helps reduce the risk of common beginner mistakes like ammonia spikes or rapid temperature changes. A 10-gallon tank also allows room for basic filtration and heating equipment, plus a few decorative elements.
For Experienced Hobbyists: Consider 5–10 Gallon Nano Tanks
If you already have some experience maintaining aquariums, a 5- to 10-gallon nano tank offers a more compact way to enjoy the hobby. These tanks are great for housing bettas or nano fish species, and they’re ideal for work desks, kitchen counters, or small apartments. Just make sure to monitor water quality regularly, as smaller volumes can change quickly.
For More Design Freedom and Fish Variety: Opt for a Larger 15–20 Gallon Tank
If you want more space for aquascaping, community fish, or a mix of species, go for a 15- to 20-gallon tank. It’s still considered a small tank by most standards, but it gives you more creative freedom and room for equipment like internal filters or CO2 diffusers. These sizes also offer more stability and reduce stress for your aquatic pets.
Match the Aquarium to the Type of Fish or Setup You Plan to Keep
Not all small aquariums can support the same kinds of fish or decorations. Think about what you want to keep inside your tank, as this will influence the size, equipment, and features you'll need.
Choose a Betta-Friendly Tank if You Want a Low-Maintenance Setup
Betta fish are often recommended for beginners because they can survive in lower-oxygen environments and small spaces. However, this has led to the misconception that they require minimal care. In reality, bettas need at least a 5-gallon tank—though 10 gallons is ideal for beginners. A larger tank provides better water quality, more space for enrichment, and is easier to maintain.
Bettas also require a heater and a gentle filter to thrive. They do best in tanks with gentle water flow, plenty of hiding spots, and warm water—ideally between 25–28°C. Avoid keeping bettas in unfiltered bowls or cramped containers, as poor water quality and limited space can quickly harm your fish.
If You’re Planning a Shrimp or Snail Tank, Go for a Stable Nano Setup
Shrimp and snails are great choices for small, low-bioload tanks. They're fun to watch and help keep the tank clean. However, they’re very sensitive to water quality and temperature swings. Choose a 2.5- to 5-gallon tank with gentle filtration (like a sponge filter), live plants, and a stable temperature. Avoid aggressive tank mates that may nip or eat them.
If You Want to Try Aquascaping, Pick a Tank With Clear Panels and Lighting
Aquascaping lets you create a living underwater garden. For this, look for tanks with ultra-clear glass or seamless acrylic for better visibility. Choose cube or rimless tanks that offer an unobstructed view of your layout. Good lighting is essential for plant growth, and a slightly larger tank (like 10–20 gallons) will give you more creative flexibility.
If You Plan to Keep Plants, Choose a Tank With Proper Lighting Features
If you plan to include live plants, lighting becomes a key feature. LED lights are energy-efficient and offer adjustable settings, making them ideal for small tanks. For basic plant species, low to medium light is fine. But if you want to grow more demanding plants, choose a light that offers at least 1–2 watts per liter and can be adjusted for intensity and color spectrum.
Choose Materials Based on Style and Safety Needs
Small aquariums come in either glass or acrylic, and each has its pros and cons. Your choice will depend on whether you prioritize looks, durability, or ease of handling.
If You Prioritize Style and Clarity, Go for a Glass Tank
Glass tanks are heavier but offer crisp clarity and are more scratch-resistant than acrylic. They’re a great choice if you want your aquarium to double as a stylish display in your living room or office. Just handle them with care during setup and cleaning, especially around the edges.
If Safety Is Your Top Concern, Pick an Acrylic Tank
Acrylic tanks are lightweight, shatter-resistant, and easier to move—making them ideal for homes with kids or pets. They're less likely to break if bumped and are also great for renters or dorm dwellers. Just be careful when cleaning, as acrylic is prone to scratching.
For Bedrooms and Offices: Check for Quiet Operation
If you plan to place your aquarium in a bedroom, workspace, or shared living area, don’t forget to check how quiet it runs. Some filters and air pumps can be surprisingly noisy, which might disrupt sleep or concentration. Look for models with “quiet” or “whisper” features, and read customer reviews for real-world feedback on sound levels.

Frequently Asked Questions
How Many Fish Can I Put In a Small Tank?
A general rule is 1 inch of fish per gallon, but this varies by species. A 10-gallon tank typically fits 4–5 small fish like tetras or guppies. Consider adult size, activity level, and social needs, as overcrowding can harm water quality and fish health.
How Do I Maintain Water Quality in a Nano Tank?
Small tanks are sensitive, so regular care is essential. Do weekly 20–30% water changes, use a proper filter, avoid overfeeding, and test water often for ammonia, nitrites, and nitrates.
