Best 1 Gallon Betta Tanks With Filters for Small Spaces
As an Amazon Associate we earn from qualifying purchases.
A 1 gallon betta tank with filter is a small all-in-one kit that bundles the tank, a pump or filter and usually an LED light, so a desk or counter setup needs fewer separate purchases. This guide compares eight kits, from true 1 gallon tanks to 1.5 gallon glass ones, using only what each listing states: size, material, lighting, filter type and what is left out. Several kits need a separate USB power adapter, so read that part before you order.
Quick answer
- For a true 1 gallon footprint with a hidden filter and a top feeding hole, look at the DaToo, Novique and AQUANEAT 1 gallon kits.
- For glass walls and a hang-on-back filter, the 1.5 gallon Craftsboys and iPriro kits are the closest matches in the group.
- For the lowest water volume, note that the AQUANEAT 1 gallon listing says usable volume is about 0.8 gallons once the filter section is deducted.
- Many of these lights run from a 5V transformer that is not in the box, so plan for the adapter.
What to check before choosing a small betta tank kit
Real water volume
A tank labeled 1 gallon does not hold 1 gallon of open water once a filter chamber, pump and decorations take space. The AQUANEAT 1 gallon listing is upfront about this: it says that after deducting the filter part, the usable volume is approximately 0.8 gallons. Other listings give only the nominal figure, so treat every number as a ceiling rather than the water your fish actually gets.
Filter style
The kits here use two designs. Some hide a sponge and small pump in a side chamber of the tank (AQUANEAT, Novique, DaToo). Others hang a small power filter on the back wall (Craftsboys, iPriro). A hidden filter keeps the tank looking clean but takes some interior room. A hang-on-back filter leaves the inside open, and the iPriro listing says this gives more room in the tank. Whichever you pick, the listings that mention flow say it is adjustable or can be softened with a sponge or decorations, which matters for a betta because long fins and strong current do not mix well.
Power and lighting
Most of the 1 gallon kits use an LED hood powered through a USB-style 5V cord. The AQUANEAT 1.2 gallon listing states that no USB power adapter is included and that the adapter must be rated at 5V and at least 2A. The AQUANEAT 1 gallon listing names compatible transformers (5V 0.5A, 1A, 1.5A or 2A) and says the transformer is not included. The DaToo listing says its lamp needs a regular 5V transformer and does not support fast charging adapters. Always match the adapter to what the listing says.
Material and weight
Acrylic and plastic kits are lightweight; the AQUANEAT 1.2 gallon listing gives 1.92 pounds for the whole product. Glass kits such as the Craftsboys and iPriro ones weigh more (the listings give 2.17 kg and 2.49 kg) and list glass thicknesses of 4.2 mm and 4 mm. Glass is heavier to carry during water changes, while the lighter plastics are easier to move but are described differently in each listing.
Heating
Bettas are tropical fish, and a tank this small changes temperature quickly. The kit listings do not mention a heater, so plan for one separately. Our guides on a betta heater for a 1-gallon tank and the best small betta tank heaters for 1 to 5 gallons cover what those listings state about size and fit.
The eight kits at a glance
| Kit | Listed volume | Listed size (L x W x H) | Material | Filter |
|---|---|---|---|---|
| AQUANEAT 1.2 gallon (HJ-111F) | 1.2 gallons | 8 x 5.25 x 7 in | Acrylic | Water filter pump with sponge |
| Craftsboys 1.5 gallon | 1.5 gallons | 6.29 x 6.29 x 8.66 in | Glass, 4.2 mm | 3W hang-on-back, adjustable flow |
| iPriro 1.5 gallon | 1.5 gallons | 6.3 x 6.3 x 8.67 in | Glass, 4 mm | Hang-on-back, 2.5W, adjustable flow |
| Nano glass kit (B0FMDYQN3S) | Title 1.5, details 2.5 gallons | 11.81 x 7.09 x 7.87 in | Glass | Filter included, type not stated |
| ERAARK 1.5 gallon | 1.5 gallons | 6.4 x 6.4 x 8.3 in | ABS | Filter cotton plus water pump |
| AQUANEAT 1 gallon | 1 gallon (about 0.8 usable) | 7.9 x 5.9 x 5.9 in | Plastic | Hidden filter, sponge, adjustable pump |
| Novique 1 gallon | 1 gallon | 7.9 x 5.7 x 5.9 in | Acrylic | Filter sponge, adjustable silent pump |
| DaToo 1 gallon | 1 gallon | 7.8 x 5.8 x 6 in | Plastic | Hidden side filter, 42 GPH, 3W pump |
AQUANEAT 1.2 gallon starter kit
This is the listing with the most plain-spoken power notes. It is an acrylic rectangle measuring 8 by 5.25 by 7 inches, with an LED hood and a water filter pump. The kit contents are the tank, a sponge, a water filter, a 5V USB power cord and two artificial plants. The listing positions it for a single betta, a couple of shrimp, snails or a small goldfish, and describes it as small enough for a desktop or kitchen counter.
Two cautions come straight from the listing. First, the pump must be fully submerged to work, and if it stops or the flow drops, the listing says to remove it, clean it and reinstall the impeller and shaft. Second, if the current is strong, the listing suggests placing a pre-filter sponge on the intake. Pick this one if you want the extra 0.2 gallon over the 1 gallon kits and can supply a 5V/2A adapter.
Craftsboys 1.5 gallon nano glass tank
The Craftsboys kit is a glass tank measuring 6.29 by 6.29 by 8.66 inches, with 4.2 mm glass. It comes with a 3W hang-on-back filter with adjustable water flow, a 3W COB LED light, decorations and a fish care guide. The listing names betta as a target species and recommends the tank for aquascape beginners. The listed warranty is one month, which is shorter than some others here, so check the listing for current terms.
The footprint is small, but the 8.66 inch height gives a taller water column than the wide 1 gallon kits. Choose it if you prefer glass and an external filter that keeps the interior open.
iPriro 1.5 gallon glass betta kit
iPriro describes a 4 mm glass tank of 6.3 by 6.3 by 8.67 inches with a black-finished back panel and a black EVA base cushion. It ships with a lid, a clip-on full-spectrum LED (listed at 8W and 450 lumen) and a hang-on filter listed at 2.5W and 250 L/H with adjustable flow. One practical instruction from the listing: fill the filter with water before every start-up.
The listing names betta, guppy and angelfish as suitable, but a tank this size only makes sense for a single small fish, so treat the betta wording as your guide. The warranty is listed as one year from the manufacturer. This is a good fit if you want the lid, the clip-on light and the longest warranty line in this group.
Nano glass kit with filter (B0FMDYQN3S)
This listing has a mismatch you should know about: the title calls it a 1.5 gallon kit, while the product details list a tank volume of 2.5 gallons and dimensions of 11.81 by 7.09 by 7.87 inches. The bullet points are brief, saying only that it is a nano glass fish tank starter kit with a filter and LED light for small fish, shrimp and betta. Because the listing does not state filter type, light wattage or glass thickness, confirm those on the page before buying.
The wider footprint is the interesting part. At nearly 12 inches long it gives a fish more horizontal swimming room than the cube tanks, if the 2.5 gallon figure is the correct one. It is the least documented kit here, so choose it only if the longer shape matters to you and you are willing to verify the details.
ERAARK 1.5 gallon aquarium kit
The ERAARK kit lists an aquarium of 6.4 by 6.4 by 8.3 inches with an LED light, a filter and a water pump. The listing says the light color can be changed (red, orange, yellow, green, blue, purple and others), and that the filter uses multiple layers of filter cotton for physical filtration. The tank is made of ABS. Fish and sand are not included, and the warranty field simply reads “NO”.
It suits someone who wants colored lighting and a basic physical filter in a compact cube. Because the listing gives little detail on pump flow, think about placing a decoration near the outlet if the current looks strong for your fish.
AQUANEAT 1 gallon betta tank
This smaller AQUANEAT kit measures 7.9 by 5.9 by 5.9 inches and is plastic. The LED hood has three colors and 10 brightness levels, there is a top feeding hole, and four silicone feet provide stability. The filtration is described as hidden, and the listing notes that the sponge and pump must be cleaned regularly and that regular water changes are required because the small tank does not support zero-maintenance use. It also lists use as a hospital or quarantine tank, though for any sick fish you should ask a vet.
The kit includes the tank, a filter sponge, an adjustable pump and the LED hood. The transformer is not included; the listing names 5V 0.5A, 1A, 1.5A and 2A as compatible. If the pump is too strong, the listing suggests placing decorations at the water inlet. Pick it if you want a plainly worded 1 gallon kit.
Novique 1 gallon acrylic aquarium kit
The Novique listing is aimed at first-time fish keepers. It describes a 7.9 by 5.7 by 5.9 inch acrylic tank with day, night and warm white lighting modes, ten brightness levels, a raised-flap feeding port, an anti-slip base, a filter sponge and an adjustable silent water pump. The listing says the equipment is hidden in the tank and that you place the pump in the black recess after opening the cover.
The acrylic is described as lightweight and impact-resistant. It is a good option if you want the feeding-flap design and a night lighting mode for a desk near a bed.
DaToo 1 gallon starter kit
DaToo lists a plastic tank of 7.8 by 5.8 by 6 inches with a three-color LED cover, 10 brightness levels and a hidden side filter. The pump is described as 3W and adjustable, with a 42 GPH flow rate and extra-thick filter cotton. Other details include a top feeding hole, a wiring slot that reduces evaporation, and a 4 mm safety suction port. The lamp needs a regular 5V transformer, and the listing says fast charging adapters are not supported.
It has the most flow and filter detail among the 1 gallon kits, which helps you judge whether the current will be gentle enough for a long-finned betta. Choose it if you want those numbers up front.
Which kit fits which situation
- Tight desk, simple setup: AQUANEAT 1 gallon, Novique or DaToo, all with hidden filters and feeding ports.
- Glass and an open interior: Craftsboys or iPriro, both with hang-on-back filters.
- More horizontal room: the B0FMDYQN3S kit, after you confirm its real volume.
- Colored lighting: ERAARK, which lists a wide range of light colors.
Mistakes to avoid with a tiny tank
- Skipping the adapter. Several lights and pumps run from a 5V supply that is not included, and the AQUANEAT 1.2 gallon listing warns that a weak adapter can stop the light or the pump.
- Running a pump dry. The AQUANEAT listing says the pump must be fully submerged.
- Ignoring maintenance. The AQUANEAT 1 gallon listing says plainly that regular water changes are still required.
- Trusting the title over the details. The B0FMDYQN3S listing shows how a title and a spec table can disagree.

FAQ
Is a 1 gallon tank with a filter enough for a betta?
The listings in this group describe 1 and 1.5 gallon kits as suitable for a single betta, and several say so directly. They do not claim a 1 gallon tank is ideal, and many fish keepers prefer larger tanks. Ask a vet or an experienced fish keeper about your own fish.
Do these kits include a heater?
The listing text for these eight kits does not mention a heater. Plan for one separately and check that its size fits the tank.
Do I need a power adapter?
Often yes. The AQUANEAT 1.2 gallon, AQUANEAT 1 gallon and DaToo listings all say the adapter or transformer is not included, and give the 5V requirements. The iPriro filter and light are listed with AC voltage ratings instead, so read each listing.
Can the filter flow be reduced?
The Craftsboys and iPriro listings say flow is adjustable, the DaToo and Novique pumps are listed as adjustable, and the two AQUANEAT listings suggest adding a sponge or decoration near the intake if the current is strong.
Is glass better than acrylic or plastic?
The listings do not rank materials. The glass kits here are heavier (2.17 and 2.49 kg listed) while the acrylic and plastic kits are described as lightweight. Pick based on how much weight you are comfortable lifting and the look you want.
How often should I clean the filter?
The AQUANEAT listings say to clean the sponge and pump regularly and to clean the pump if flow drops. They give no fixed schedule, so follow the listing instructions and watch the flow.
Bottom line
Choose by the filter and power details, not the picture: pick a hidden-filter 1 gallon kit for the simplest desk setup, a glass hang-on-back kit if you want an open interior, and confirm the adapter, the heater and the real water volume before you order. A vet can answer questions about your fish’s health.
