Betta Fish Necessities: Best Gear for Beginners
As an Amazon Associate we earn from qualifying purchases.
Betta fish necessities come down to a few groups of gear: a tank, filtration and aeration, a way to keep the water at a steady temperature and check it, and a light on a schedule. This guide sorts seven listings by which of those jobs they cover. Three are complete or near-complete starter kits, and four are small lights for nano tanks. The listing text is our only source for what each one contains, so we call out what is included and what the listing leaves out.
Quick answer
- If you want one box with tank, heater, thermometer, filter, air pump and light, the eWonLife 3.5 gallon kit lists all of them.
- If you already have a tank, the Penn-Plax Cascade kit supplies the air pump, sponge filter, tubing, thermometer and extras, but tank and fish are sold separately.
- For the smallest all-in-one tank, the Aquaneat 1.2 gallon kit includes a filter and LED hood, but it needs a power adapter you must supply.
- For a light only, the AREPK, Hiro and PUEUTU lamps are sized for nano tanks of a few gallons.
- For any health concern about your fish, ask a vet who treats fish.
The checklist of necessities
1. A tank with room to swim
The tanks in these listings range from 1.2 gallons to 3.5 gallons. The Aquaneat listing says its tank suits a single betta, a couple of shrimp, snails or a small goldfish. The eWonLife listing calls its 3.5 gallon tank an ideal home for a betta, with room for small schooling fish and ornamental additions. A bigger tank gives you more water to dilute waste and more room for decor. Our guide to how to introduce a betta fish to a new tank covers the first day.
2. Filtration
Two of the starter options use sponge filtration. The Penn-Plax kit lists a mini sponge filter driven by an air pump. The eWonLife kit lists a sponge filter first, followed by ceramic rings and quartz balls for beneficial bacteria. The Aquaneat kit lists a water filter and a sponge. Sponge filters give a gentle current.
3. A heater and a thermometer
Only the eWonLife listing includes a heater: a 25W unit that the listing says holds a preset 78 degrees Fahrenheit, with a digital thermometer. The Penn-Plax kit includes a strip thermometer but no heater. The other listings do not mention either. If your room is cool, a heater is a separate purchase, and a thermometer lets you check the number rather than guess.
4. Light on a schedule
A light is on this list because you need to see your fish and because most tank decorations and plants look better lit. A timer keeps the day length regular. The eWonLife kit includes an LED with a timer, and the AREPK lamps list a timer for auto on and off. We have pages on whether a betta light should stay on at night and the day and night setup.
5. Water conditioner, a net and maintenance tools
The eWonLife listing includes a water changer and a net, and the Penn-Plax kit includes a 3-inch net and a cleaning sponge. No listing here includes water conditioner, so plan to buy it separately and follow the label.

The kits
eWonLife 3.5 gallon betta tank kit: the most complete listing
This plastic tank measures 15 by 7.9 by 8.3 inches. The listing says it includes a multi-stage filtration system, an air pump, a heater, a digital thermometer, an LED light with timer, a water changer and a net. Its item highlights include rear filtration, an adjustable pump and a 25W heater with a preset of 78 degrees Fahrenheit, plus an LED thermometer. The listing says a hidden storage design tucks the heater and filter out of view, and the filter uses a sponge followed by ceramic rings and quartz balls. A one-year warranty is listed.
Who it suits: a beginner who wants to buy once. Watch for: the listing describes the heater as preset, so you cannot choose a different temperature from the text. Check the manual before filling the tank.
Penn-Plax Cascade Betta Starter Kit: gear without the tank
This nine-piece set lists a Cascade nano air pump (model SAX7) rated at 43 dB and 1.2 liters per minute with a 26.5 inch power cable, a mini sponge filter, 2.5 feet of airline tubing, a check valve, a betta leaf, a cleaning sponge, a 3-inch net, a strip thermometer and one pound of decorative zeolite crystals. The listing says the zeolite absorbs ammonia, and that the sponge filter circulates water softly. The listing states that fish and tank are sold separately.
Who it suits: someone with a tank already, or who plans to buy the tank elsewhere. Watch for: no heater and no light are included.
Aquaneat 1.2 gallon tank kit: the small desktop option
This acrylic tank is listed at 8 by 5.25 by 7 inches, with an LED hood, a sponge, a water filter, a 5V USB power cord and two artificial plants. The listing says the filtration reduces how often you change water. It notes that no USB power adapter is included and that you need one rated at least 5V and 2A, and says that if the current is too strong a pre-filter sponge on the intake will reduce it. The listing also tells you to remove and clean the pump if the flow drops.
Who it suits: a desk or counter with little room. Watch for: the small volume and the adapter.
The lights
If you already have a tank, a light can be the missing piece. Four lights in this comparison suit nano tanks. Check the rim, space and power source before ordering.
AREPK full spectrum LED, for tanks under 7 gallons
The title says the lamp has a timer for auto on and off and suits tanks under 7 gallons. The specs list 9 watts, a 6000K color temperature, a bamboo board, a flexible gooseneck that moves 360 degrees and a 50-inch USB cord. The box includes the lamp, bamboo board, manual, a 5V 1A adapter and six clear adhesive bumper pads. The base material is aluminum and the mounting type is tabletop.
Who it suits: a keeper with a tank in the 3 to 7 gallon range who wants a timer built in. Watch for: the lamp sits on a board on top of the tank, so check the footprint against your tank.
AREPK full spectrum LED, for tanks under 3 gallons
This smaller version of the AREPK lamp lists 5 watts, the same 6000K color temperature, bamboo board and gooseneck, and similar USB power. It measures 9 by 8.6 by 15.7 inches and weighs 0.89 kg. The title notes a timer for auto on and off and suitability for tanks under 3 gallons.
Who it suits: small betta tanks. Watch for: the same board-on-top layout.
Hiro Aquatics full spectrum LED with bamboo board
This lamp is listed at 5 watts and 6000K, with a CRI above 80 and 100 to 240 volt input with a US two-pin plug. The bamboo board measures 8.5 by 9 inches and the listing says it holds a light at a maximum height of 18 inches. The lamp swivels 360 degrees, and each bead has a lens to spread light. A one-year warranty and lifetime tech support from Hiro Aquatics are listed. The listing also says it can be used as a plant light or desk light.
Who it suits: a keeper who wants a lamp that doubles for plants. Watch for: specs call the control type “remote” while the bullets list a push button, so confirm the control before relying on it.
PUEUTU clip-on light, white and black versions
Two listings from PUEUTU describe the same clip-on lamp in different colors and bases: one is listed with a white shade and an E27 base, the other with a black shade and an E14 base. Both list 48 LED beads, three lighting modes, ten brightness levels, a USB 5V 8W supply and a 4.4-foot cord. The clip is described for 1 to 5 gallon tanks with a rim of about 0.11 to 0.3 inches, and the arm is described as a thickened metal swivel neck.
Who it suits: a tank with a thin rim where a clip works. Watch for: rim thickness. If your tank has a thicker rim or none, a clip will not fit.

What is missing from every list
None of the listings includes water conditioner, food or a substrate. Substrate and decor depend on your taste, and the listings include only a few items such as artificial plants (Aquaneat) and a betta leaf (Penn-Plax). Food and conditioner are small purchases but easy to forget. For feeding questions such as what happens if you leave for a few days, the topic is covered separately on this site.
The listings also do not state a recommended tank size for a betta, so we do not claim one. If you are unsure, ask a vet who treats fish or follow the guidance on a reputable fish-care page.
Which route to choose
You have nothing yet
The eWonLife kit is the only listing here that includes a tank, heater, thermometer, filter, air pump and light. It is the closest to a single-box start.
You have a tank
The Penn-Plax kit covers air and filtration, and you add a heater and a light. Pair it with the AREPK or Hiro lamp if you need lighting.
You have a very small space
The Aquaneat 1.2 gallon is the most compact kit. Remember the adapter.
You only need light
Match the lamp to the tank: the AREPK under 3 gallon for small tanks, the AREPK under 7 gallon for larger ones, the PUEUTU clip if your rim is thin, the Hiro if you want a lamp for plants too.
Mistakes to avoid
- Buying a light without checking whether it sits on top of the tank or clips on the rim.
- Forgetting the power adapter for the Aquaneat kit.
- Assuming the Penn-Plax kit includes a tank. It does not.
- Assuming every starter kit includes a heater. Only the eWonLife listing does.
- Putting the fish in before the equipment is running and checked.
- Leaving the light on all the time instead of on a schedule.
FAQ
What do I need for a betta fish at minimum?
A tank, a filter or air pump with sponge, a thermometer, a heater if your room is cool, a light, a net, and water conditioner. The listings here cover most items, but not conditioner or food.
Which kit includes a heater?
The eWonLife 3.5 gallon listing includes a 25W heater with a preset of 78 degrees Fahrenheit. None of the others lists one.
Does the Penn-Plax kit include a tank?
No. The listing says the fish and tank are sold separately.
Can I use a lamp that is not meant for aquariums?
The lamps listed here are marketed for aquariums and also for plants. We do not advise on other lamps, because the listings do not cover them.
Do I need a timer for the light?
The eWonLife and AREPK listings include a timer, and the PUEUTU and Hiro listings do not mention one. A separate plug-in timer is an alternative.
What if my betta looks unwell after setup?
Ask a vet who treats fish. We do not give treatment advice.
Bottom line
Pick by what you already own. For a full start, choose the eWonLife kit. If you have a tank, the Penn-Plax kit gives you air, filtration and tools, and one of the lamps adds light. For the smallest footprint, the Aquaneat kit works if you supply the adapter.
