Top 5 Picks
#1
Best Budget
AQUANEAT Fish Tank, 1 Gallon Betta Fish Tank, Small Aquarium Kit with LED Light and Water Filter Pump
We picked this 1-gallon kit for its affordable price and essential features including LED light and filter. It's a solid starter tank for a single betta, though we wish the lid fit more securely.
#2
Best Value
Tetra LED Half Moon Aquarium Kit, 1.1 Gallons, Small, Clear Plastic Fish Tank With Curved Front, Easy Feeding And Movable, Energy-Efficient LEDs Ideal For Bettas Great As Desk Aquarium
Our team chose this kit for its impressive all-in-one design: built-in LED, gentle waterfall filter, and clear plastic body that won't shatter. It's the easiest to set up and maintain among the group.
#3
Best Premium
Tokenkuko Fake Motion Fish Tank Mini Aquarium, Artificial Tropical Decorative Lamp Night Light with Moving Fish, Gift for Family(US Plug)
We selected this artificial tank for those who want the look of fish without maintenance. The motion simulation is convincing, and the LED backlight adds ambiance. It's not for live animals.
#4
Runner-Up
AWXZOM Small Nano Tall Rimless Tank, Glass Fish Tank, Betta Tank (0.7 Gallon, 5.9x4.3x5.1in/15x11x13cm)
We like this rimless glass tank for its clean aesthetics and sturdy build. The tall shape is ideal for a betta or nano aquascape. However, it lacks a filter or light, so factor those in.
#5

While this is a fish net, not a tank, we included it as a practical accessory for cleaning any small tank. The fine mesh and small size make it perfect for nano aquariums.
Before You Buy
Key Buying Factors
01
Tank Material
Glass offers clarity and scratch resistance; plastic is lighter and less prone to breaking. We preferred glass for permanent displays.
02
Filtration & Aeration
Small tanks often rely on included filters or require separate purchase. We prioritized kits with built-in filtration for maintenance ease.
03
Lighting Quality
LED lights support plant growth and viewing. We looked for bright, energy-efficient lights with sufficient coverage.
04
Ease of Maintenance
Access for cleaning, water changes, and feeding matters. We favored tanks with wide openings and removable lids.
05
Included Accessories
Kits that include net, thermometer, or starter filter media save money. We evaluated completeness of each package.
06
Size & Footprint
Small tanks fit desks but limit fish options. We considered footprint and shape for stability and aesthetics.
Living With It
Care, Cost and Maintenance
Water Quality
Perform 25% water changes weekly using dechlorinated water. Test ammonia, nitrite, and pH regularly.
Feeding
Feed small amounts once or twice daily, removing uneaten food to prevent waste buildup.
Tank Maintenance
Clean glass gently, rinse filter media in tank water monthly, and avoid overstocking.
Pro tip
For easiest maintenance, choose a tank with a wide opening and a filter that creates gentle flow. Avoid tiny tanks if you're not committed to frequent water changes.
Frequently asked questions
What is the minimum tank size for a betta fish?
We recommend at least 1 gallon, though 2.5 gallons or larger is better for long-term health.
Can I keep live plants in a small tank?
Yes, with proper LED lighting. Low-light plants like java fern and anubias work well in small tanks.
How often should I clean a 1-gallon tank?
We suggest 25% water changes every 3-4 days and a thorough cleaning once a month.
Is a filter necessary in a small tank?
A filter helps maintain water quality, but you can keep a small tank without it if you perform more frequent water changes.
What fish can live in a 1-gallon tank?
Only a betta or shrimp. Most other fish require more space.
