Best Nano Betta Tanks for Small Spaces
As an Amazon Associate we earn from qualifying purchases.
A nano betta tank is a small aquarium, usually a few gallons, that fits on a desk, shelf or counter. This guide compares seven small tanks and one small light from the product data, using only what each listing states: volume, dimensions, glass thickness, filter and light details, and what comes in the box. Several listings disagree with themselves on size, and those cases are flagged so you can check before ordering. For the wider process of getting a tank ready, read our betta fish tank setup page.
Quick answer
- For the smallest footprint, the Craftsboys 1.5 gallon kit and the AWXZOM rimless cube are the compact choices.
- For a longer 3 gallon shape with filter, light and lid, the iPriro glass tanks are the closest match.
- For a round, tall tank with color lighting, the YISITONG 3 gallon is the one that offers it.
- The LAQUAL is the largest here at 10 gallons, so it is a bigger step than “nano”.
How to choose a nano betta tank
Check the real volume, not just the title
Two listings in this set give conflicting size information. The AWXZOM title says 1.1 gallon and 7.8 by 5.5 by 5.9 inches, but its first bullet says about 11.8 by 6.7 by 7.8 inches and approximately 2.85 gallons, and the spec table also says 2.85 gallons. The AQUA DAREN title says 1.5 gallon, while the spec table says 2.5 gallons and 11.81 by 7.09 by 7.87 inches. Ask the seller or read the full listing before you buy, because the volume decides what the tank can hold comfortably.
Look at the material
Four of the tanks are glass. The Craftsboys glass is listed at 4.2 mm, the iPriro at 4 mm and the LAQUAL at 5 mm. The AWXZOM is listed at 5 mm thickness in a bullet. The YISITONG is described as acrylic in its bullet while its spec table says ABS, so confirm which before you buy.
Decide whether you want the equipment in the box
Some listings include a filter and light. The Craftsboys, AQUA DAREN, iPriro and YISITONG listings do. The LAQUAL listing lists covers, clips, a feeding ring and cleaning tools but does not list a filter or a light. The AWXZOM spec table says “Lid or hood, likely includes a filter”, which is not a firm statement, so treat the filter as unconfirmed.
Plan for heat and care
None of the tank listings in this set states a heater. Tank size, heating and water quality all matter for a betta. If you are new, ask a fish keeper or a vet for guidance on temperature and care, and see the care pages on this site.

The tanks one by one
Craftsboys 1.5 gallon glass kit
This is the smallest tank by stated volume. The listing gives 1.5 gallons, a size of 6.29 by 6.29 by 8.66 inches, 4.2 mm glass and a weight of 2.17 kg. A 3 watt hang-on-back filter with adjustable water flow and a 3 watt COB LED light are included, along with decorations and a fish care guide.
The listing recommends it for aquascape beginners and small fish and lists a one month warranty. It is a good match for a very small desk space. The listing does not say it is a tank for a betta alone, so the small volume is the main thing to weigh.
AQUA DAREN glass starter kit
The listing is thin: it says nano glass tank with filter and LED light for shrimp, small fish and betta. The title says 1.5 gallon but the spec table says 2.5 gallons, with a size of 11.81 by 7.09 by 7.87 inches, a weight of 2.17 kg and a black background. Included components list a light.
Because the data conflicts, do not assume either volume until you confirm it on the full listing. The glass material is stated but the thickness is not.
AWXZOM rimless nano tank
A rimless low-iron glass cube, with extra-clear glass and 5 mm thickness. The bullet gives about 11.8 by 6.7 by 7.8 inches and approximately 2.85 gallons, and the spec table repeats 2.85 gallons and a weight of 1.46 kg. The title gives a smaller size, so confirm.
The listing says the tank can house betta, guppies and other small animals, and the warranty is one month. It does not clearly say whether a filter is included, so plan to buy one if the full listing does not confirm it.
iPriro 3 gallon glass tank, white
The listing gives 3 gallons, 12.6 by 6.3 by 8.67 inches, 4 mm glass with a black back panel and a black EVA cushion on the bottom, and a custom lid. The hang-on-back filter is listed at 2.5 watts and 250 liters per hour, with adjustable flow, and the listing reminds you to fill the filter with water before each start-up. The clip-on light is listed at 13 watts and 780 lumens.
A separator plate is included, and the listing says dividers allow two bettas to be kept side by side. If you plan to use a divider, ask an experienced keeper first, as a divider changes the swimming space each fish gets. The weight is 3.8 kg and the warranty is one year.
iPriro 3 gallon glass tank, black
The same tank and equipment as the white version, in black glass. The listing again gives 3 gallons, 12.6 by 6.3 by 8.67 inches, the 2.5 watt filter with adjustable flow, the 13 watt 780 lumen light, the lid and the separator. It weighs 3.79 kg and has a one year warranty.
Choose between the white and black versions on looks and on how the tank sits in your room. The facts are otherwise the same.
YISITONG 3 gallon round tank
A different shape: cylindrical, 7.9 by 7.9 by 11.8 inches, 3 gallons and light at 500 grams. The listing describes a built-in 2-in-1 filter and a clip-on light with a 24-key remote and 16 static colors. It says the walls transmit more than 90 percent of light and give a 360 degree view.
The material is listed as ABS in the specs and as acrylic in a bullet, so confirm. The shape suits a desk where the tank is viewed from all sides.
LAQUAL 10 gallon rimless glass tank
This tank is much larger, at 10 gallons and 20 by 10.4 by 12 inches, with 5 mm low-iron glass edges the listing says are made with German Wacker glue. It weighs 8.53 kg. The box includes the tank, four acrylic cover clips, three adjustable covers, a floating feeding ring 3 inches across, two cleaning sponges, a sponge scraper and a 15 inch tweezer.
The listing offers a 90 day return policy and one year of quality service. No filter, heater or light is listed. It is the pick when you want room to grow, not when you need the smallest footprint.
HIRO AQUATICS bamboo board LED, for a bare tank
If your chosen tank has no light, this 5 watt, 6000K LED lamp on an 8.5 by 9 inch bamboo board is described as fitting small aquariums, with a maximum light height of 18 inches. It swivels 360 degrees and has a one year warranty. It is an accessory rather than a tank, so check your tank footprint against the board size.
Filters and lights compared
Equipment is where the kits differ most. The Craftsboys listing gives a 3 watt hang-on-back filter with adjustable flow and a 3 watt COB LED. The iPriro listings give a 2.5 watt filter rated at 250 liters per hour with adjustable flow, and a 13 watt, 780 lumen clip-on light that runs on 110 to 240 volts. The YISITONG listing describes a quiet wall-mounted 2-in-1 filter and a multi-color light with a 24-key remote. The AQUA DAREN listing only says filter and LED light, with no wattage. Adjustable flow is worth noting because a strong current in a small tank can be a nuisance for a long-finned fish, and the listings that state adjustable flow give you a way to turn it down. None of the listings explains filter media in detail, so read the full listing for replacement parts.
For lighting, the LAQUAL and AWXZOM listings do not list a lamp, which is where the HIRO bamboo-board light or another lamp comes in. Match any lamp to the tank footprint and the lid style before you order.
Space and placement
Before ordering, measure the spot. The longest tank here, the LAQUAL, is 20 inches long, while the Craftsboys is about 6.3 inches square. Water is heavy, glass adds weight, and the listed item weights (1.46 kg for the AWXZOM up to 8.53 kg for the LAQUAL) are for the empty tank only. Pick a stable, level surface and check that cords reach an outlet.
Which one should you pick?
For a bare-bones start on a tiny footprint, choose the Craftsboys kit and confirm it is big enough for your plans. For more length and a ready equipment package, choose the iPriro. For a round display choose the YISITONG after confirming the material. For the most space, choose the LAQUAL and add your own filter, light and heater. The AQUA DAREN and AWXZOM need extra confirmation of volume first. If you are weighing small against large, see our page on nano betta tanks and 20-gallon aquariums compared.
Mistakes to avoid
- Trusting the title volume when the spec table says something else.
- Assuming a lid or filter is included when the listing only says “likely”.
- Forgetting to fill the iPriro filter with water before start-up, as the listing instructs.
- Buying a kit with no heater and assuming the water will be warm enough. Ask a fish keeper or vet about betta temperature.
- Treating a divider as a substitute for proper space. Get advice from an experienced keeper.
FAQ
How big is a nano betta tank?
The listings here range from 1.5 to 3 gallons for the nano kits, with one 10 gallon tank. Confirm the stated volume, as two titles conflict with their spec tables.
Which tank includes a filter and light?
The Craftsboys, iPriro, YISITONG and AQUA DAREN listings state a filter and light. The LAQUAL and the AWXZOM do not clearly state them.
Which tank has a separator?
The two iPriro tanks list a separator plate. Ask an experienced keeper before using any divider.
Is glass or acrylic better?
The listings do not compare them. Glass thickness is given as 4 to 5 mm on several tanks, and the YISITONG is listed as ABS or acrylic. Choose by size and equipment.
Do these tanks come with a heater?
None of the seven tank listings in this set lists a heater, so ask a fish keeper or vet how to keep the water at a suitable temperature.
Is the LAQUAL a nano tank?
The listing calls it suitable for betta and nano use, but at 10 gallons it is much larger than the others here.
Bottom line
Pick the tank whose stated size and equipment you can confirm. The iPriro 3 gallon is the most complete package in this set, the Craftsboys is the smallest, and the LAQUAL gives the most room but needs its own equipment.
