GloFish 3 Gallon Betta Aquarium Kit Review for Beginners
As an Amazon Associate we earn from qualifying purchases.
If you are shopping for a GloFish 3 gallon betta aquarium kit, one thing to know first: none of the listings in our product data carries the GloFish name, so this page cannot describe a GloFish-branded kit. What it can do is review the closest match in the data, the Koller Products 3-gallon starter kit, and compare it with three other 3 to 3.5 gallon kits that are sold for bettas. Everything below is taken from the listings. If you specifically want the GloFish brand, check its own product page for its details.
Quick answer
- No GloFish-branded listing is in our data, so nothing here describes one.
- The Koller 3-gallon kit lists a 25 gallons-per-hour filter, four LED modes with a timer, a full lid and plastic construction.
- The SW Products 3-gallon kit is a near twin with a 7-color LED and a 30 dB filter.
- The Bluecoco kit is glass on four sides; the eWonLife kit adds a heater and thermometer.
What the Koller 3-gallon kit includes
The listing names the contents as the fish tank, a full lid, a Koller Products XS filter cartridge, LED lighting, a power filter and a user set-up guide. The listing states a 1-year manufacturer warranty. It does not list a heater, a thermometer or a net, so those are separate purchases if you want them.
Size and build
The tank is listed at 14.75 inches long, 10.25 inches wide and 9.5 inches high, with a weight of 4.2 pounds. The material is plastic, described as impact-resistant with a crystal-clear finish, and the listing says it fits on desks, cabinets and office surfaces. The volume is 3 gallons. That footprint is wide and low rather than tall, which matters for placement: you need about 15 by 10 inches of flat surface.
Filtration
The built-in filter is listed at a flow rate of 25 gallons per hour and operating below 35 dB. It is compatible with SW Products and Koller Products XS filter cartridges. The listing says the filter helps maintain a cleaner environment for fish, and it calls the setup quiet. It does not say whether the flow can be adjusted, and the sister SW Products listing describes its flow as fixed, so assume the Koller flow is also fixed unless the full product page says otherwise.
Lighting
The light offers four modes: daylight white, warm white, blue and blue-white. A timer runs the light for 2, 4 or 8 hours and turns it on at the same time the next day. For a beginner this is the most useful convenience in the kit, since it keeps a regular light cycle without daily switching. The listing describes it as a lighting cycle, not a plant-growth light, and gives no wattage or lumen figure.
What the listing leaves out
No heater, thermometer, test kit, dechlorinator, food or decor is listed. A betta is a tropical fish, so a beginner should plan to add heat and a thermometer, and ask a fish store or a vet about water treatment and feeding. The listing also does not state an adapter type beyond the power filter being part of the kit.
Who the Koller kit suits
It suits a keeper who wants a plastic, lightweight tank with a lid, a quiet filter and a light on a timer, and who is happy to add a heater separately. It is less suited to someone who wants every piece in one box, or who wants a glass tank.
Three close alternatives from the same data
SW Products 3-Gallon Aquarium Starter Kit
This listing reads like the Koller kit’s sibling. It is a 3 gallon plastic tank, 11 x 11 x 11.25 inches and 2 pounds, with a fixed-flow internal filter at 25 GPH and 30 dB, a 7-color LED with an Always-On, 2 hour or 4 hour timer that remembers its last setting, a full hood, an XS filter cartridge, a power adapter and an illustrated guide. The listing says the filter flow is fixed and that the adjustable settings apply to the light only. It also gives a care routine: rinse the tank with cold water only before first use, never with soap or warm water, wipe the interior with a soft algae pad every 2 to 4 weeks, and replace the filter cartridge monthly. The footprint is square, which suits a shelf better than the Koller’s wide shape.
Bluecoco 3 Gallon Glass Aquarium Betta Kit with Flip-Top Port
A glass tank with high-definition glass on all four sides, listed at 3 gallons and 3.74 kg, in black. The filtration is an integrated chamber with filter cotton and a top-mounted rain-shower-style drip system with adjustable air valves. The listing describes a quiet pump that combines aeration, circulation and pumping, LED lighting and a flip-top feeding port that avoids opening the whole lid. Included components are an air pump, filter, LED lighting and the glass aquarium. No heater is listed, and the listing gives no dimensions in the data provided.
eWonLife 3.5 Gallon Betta Fish Tank, All in One
A slightly larger acrylic tank at 3.5 gallons, 14.96 x 7.87 x 8.27 inches and 7.9 pounds. It lists a multi-stage filter (sponge, ceramic rings and quartz balls), a heater set to 78°F, a digital thermometer, an LED light with a timer, a water changer and a net, with a one-year warranty. It is the only one of the four that lists heating and a thermometer, which makes it the most complete box for a beginner.

How to choose between them
Shape and shelf space
The Koller kit is wide and low, the SW Products kit is a cube, and the eWonLife kit is long and shallow. Measure your shelf first, because the footprints differ by several inches.
Plastic or glass
The plastic kits are light, 2 to 4.2 pounds as listed. The SW Products listing calls its plastic safer around children and pets than glass. The Bluecoco kit is glass on all four sides for viewing. Pick by where the tank will sit and who will be near it.
Heat and measurement
Only the eWonLife listing includes a heater and a thermometer. For the other three, add both. If you are unsure which to choose, ask a fish store.
Light control
The Koller and SW Products kits give you timers. The Bluecoco listing mentions LED lighting without a timer. A timer matters to keep a regular day and night routine.
Setting up a kit like this: what the listings tell you
Pulling the set-up notes from the four listings gives a short checklist. First, clean the tank the way the maker says: the SW Products listing says cold water only, never soap or warm water. Second, fill the filter where the listing asks you to; some filter designs need priming with water before start-up, so read the guide that comes with yours. Third, place the tank on a flat surface that matches the listed footprint, remembering that the Koller kit is 14.75 inches long and the eWonLife kit is almost 15 inches long. Fourth, set the light timer, which on the Koller kit runs 2, 4 or 8 hours and repeats each day. Fifth, add a heater and thermometer if the kit lacks them. The listings do not describe how long to wait before adding a fish or how to cycle the tank, so for that step ask a fish store or a vet rather than guessing.
The wiring is also worth a glance. The Koller kit lists a power filter and LED lighting and the SW Products listing lists a power adapter in the box. Where a listing does not say what power supply is included, check the product page before you buy so you are not left waiting on an extra part.
Common mistakes with a first kit
- Assuming the brand you searched for is the brand you are reading about. Read the maker named on each listing.
- Skipping the heater. Three of the four listings do not include one.
- Using soap or warm water on a new plastic tank. The SW Products listing says rinse with cold water only.
- Forgetting the cartridge schedule. The SW Products listing says to replace the filter cartridge monthly.
- Expecting the filter flow to adjust. The SW Products listing says it is fixed, so judge whether 25 GPH suits a small tank before buying.
FAQ
Is there a GloFish kit in this comparison?
No. None of the listings here carries the GloFish name, so we do not describe any GloFish product. The kits above are close alternatives by size.
Does the Koller kit include a heater?
The listing does not list one. Its components are the tank, full lid, XS filter cartridge, LED lighting, power filter and set-up guide.
How loud is the filter?
The Koller listing says it runs below 35 dB and the SW Products listing says 30 dB. These are the sellers’ figures.
How often should I change the filter cartridge?
The SW Products listing says monthly for optimal water quality. The Koller listing does not state a schedule, and its cartridge is the same XS type, so check its set-up guide.
Is plastic or glass better?
The listings do not rank them. Plastic is lighter and the SW Products listing calls it safer around children and pets; the Bluecoco glass tank offers clear sides on all four faces. Choose by weight and placement.
Bottom line
If a GloFish-branded kit is what you want, look at that brand’s own page, because we cannot describe it. If you want a 3 gallon plastic kit with a quiet filter and a timed light, the Koller kit fits and you add a heater. If you want heat and a thermometer in the box, take the eWonLife kit.
