Why we like it: The filter housing is huge and perfect for those who want to use several types of filter media to customize their aquarium. For those who prefer a planted tank, the included LEDs can support both medium and low-light plants.
Items Included:
5-gallon glass aquarium
LED lights
Low-voltage transformer (for the LED lights)
Circulation pump with an output nozzle
Fluval foam filter block with handle
Fluval activated carbon insert
Fluval BioMax insert
Filter
The filter that comes with this tank has an adjustable flow, but it’s still too strong for bettas. Fluval actually makes an inexpensive sponge baffle to use with the filter, so it’s an easy fix.
The sizable filter is built into the tank. It doesn’t take up any of your fish’s swimming space, and it contains a large piece of sponge for beneficial bacteria to grow on (you’ll learn more about this in our section on how to cycle a tank).
The filter housing offers some extra space for those who would like to customize their media. It’s also a great place to hide a heater. The filter media is easy to remove from the housing, which makes cleaning a breeze. Best of all, the filter is actually quiet!
Lighting
The LEDs on this tank are very bright and can be switched between white and blue to mimic day and night. They are placed above the tank on a strip that spans the entire length of the tank, leaving not a corner of the aquarium unlit.
While other tanks on our list only support low-light plants, the lights on this Fluval aquarium are good enough for medium-light plants as well. However, if you’re looking for a cheaper alternative, the Marina Led Aquarium Kit also includes LEDs capable of supporting medium-light plants.
Lid
The plastic lid on this tank is decent but could be better. The feeding hole in the center is huge, making it easy for fish to escape and water to evaporate. There are no notches for extra cords, which could be problematic if you don’t want to put a heater in the filter housing.
Design
The design of this tank is rather sleek. This is likely due to the placement of the filter housing and the honeycomb design around it, as well as the black base.
However, the designers could have done a better job when it comes to the air pump. It is difficult to get into place, which means it can be equally difficult to remove. Luckily, you shouldn’t have to remove it all that often because the filter housing is unlikely to get clogged with debris.
Pros
Sleek design
Lights support medium and low-light plants
Quiet filter with a large sponge for bacterial growth
Why we like it: This kit has it all. Not only do you get a tank with LED lights and a filter, but you also get a heater, fish food, a net, and other necessities. The size is also great for those looking to keep a sorority of bettas.
Items Included:
10-gallon glass aquarium with lid
LED lighting
Filter with cartridge
Heater
Fish food
Water conditioner
Net
Stick-on thermometer
Filter
The filter is too strong for bettas and will need to be baffled. It also has some issues with noise: it tends to vibrate against the glass. This can be fixed by putting something behind it like a piece of rubber or sponge.
One of the nice aspects of this filter is the replacement indicator. A red light will flash when it’s time to change the filter’s cartridge. This is especially useful for those new to fish keeping.
Lighting
This tank has white lights that are very bright and can support low-light plants. However, the lights can get quite hot and even heat up the water, so make sure you keep a thermometer in your tank to monitor the temperature.
Because the lights are in the lid and are not waterproof, there is a chance that condensation could reduce their longevity. If you’re okay with a smaller tank, the Marina LED Aquarium Kit comes with all the bells and whistles but has better lights.
Lid
The major issue with this lid is that it houses the lights. Because they aren’t waterproof, they don’t last, and the whole lid needs to be replaced just to get working lights again. Luckily, there is some extra room at the back for additions, so you may be able to sneak a new light through there if needed.
This lid does not have a hinge and will need to be taken off completely during cleaning. However, it does have a covered feeding hole, which is convenient and prevents escapes.
Design
The Aqueon 10-gallon aquarium is your classic rectangular glass tank. It’s made of several pieces of glass glued together and sealed with silicone caulk. The quality control here isn’t great. While the tank isn’t likely to leak, the sealant is rather sloppily laid along the seams, so you may feel better keeping some spare silicone sealant on hand to prevent leaks.
The size of this tank means you can add more fish to it. Check out our list of appropriate tank mates for bettas.
Heater
This is the only kit that comes with a heater! You could consider this a rare find.
The heater is preset at 78°F and not adjustable. This is an appropriate temperature for a betta, but if you ever wanted to house something else in this tank down the line, you wouldn’t be able to adjust the temperature.
The thermometer that comes with the heater is a nice addition, but it is a bit difficult to see without a flashlight.
Pros
Size is better for those looking to keep betta sororities or add tank mates
Comes with a heater
Comes with accessories (thermometer, water conditioner, etc.)
The feeding hole in the lid can be closed to prevent escape
Cons
Lights wear out quickly from exposure to condensation
Why we like it: The shape of this tank makes it perfect for small spaces. The LED lights mimic sunlight and moonlight, are strong enough to support low-light plants, and are height adjustable.
Items Included:
5-gallon glass aquarium with sliding lid
Filter, pump, and cartridge
Marineland bio-foam
Blue and white LED lights
Aquarium base
Filter
The filter included with this aquarium is nice and quiet, and replacement cartridges are easy to find online and in pet stores. While the flow is adjustable, the current is still too strong for a betta even at the lowest setting. However, this can be fixed with a baffle.
The area in which the filter is housed is rather narrow and thus difficult to clean. Luckily, the rest of the tank is easy to maintain.
Lighting
This tank includes a height-adjustable LED light with two different color options: white and blue. The white is meant to act as an artificial sun, whereas the blue is supposed to mimic the moon. This is a nice option for bettas since they are diurnal.
These LED lights are super bright, which is both good and bad. They’re great at illuminating the tank, but some bettas are stressed out by them. To reduce stress, try covering the lights with a piece of masking tape or some nylon stockings.
If you’re interested in a planted tank, these LEDs are capable of supporting low-light plants like moss balls or Anubias.
Lid
This tank has a sliding lid, which is nice for feeding. Unfortunately, the quality of this lid isn’t the best, with it often being a bit too narrow. If you don’t place it just right, then it may even fall into the water.
Design
This tank is tall rather than wide, which means it takes up less space and is perfect for those looking for a small aquarium. However, fish prefer to swim from side to side rather than up and down.
This MarineLand aquarium also comes with a base, but the tank simply sits on top of it rather than latching in. Despite this, it’s unlikely that the tank would actually slide off the base.
The front of the tank is made from a single piece of glass with curved edges. This reduces the chance of leaks but somewhat inhibits your view into the tank. If you look from the sides, the curved edges create a sort of Fresnel lens effect.
The filter and lights do not share the same power cord, which means you can keep the filter running continuously while having the lights on a timer. All in all, you will need three available outlets for the filter, lights, and a heater (which you have to purchase separately).
Pros
Quiet filter
Takes up less space than classic wide tanks
LEDs are strong enough for low-light plants
LED lights are height adjustable
Cons
Filter is too strong for Bettas and requires modification
Filter housing is narrow and difficult to clean
Lid is narrow and may fall into the tank if not placed perfectly
Why we like it: This tank is perfect for beginners who want a simple set-up and aren’t concerned with growing plants. It comes with a betta-safe filter and doesn’t take up a lot of space.
Items Included:
5-gallon acrylic tank with lid
LED lights
Filter with cartridge
Aquarium base
Filter
This filter has adjustable flow settings, and you’ll need to choose the lowest one to keep your betta comfortable. There is a pocket on the filter that fish can swim into, so you may want to block it with a sponge.
The filter is nice and quiet, but it is quite large. This means it will accommodate any filter media, not just the provided Bio-Bag cartridge. However, it takes up more space in the tank.
Lighting
The LED lights on this tank only come in one color: white. They are not able to support plant life. If you’re looking for an affordable tank with lights that can support low-light plant growth, then check out the GloFish Aquarium Kit instead.
Lid
The lid on this tank is just okay. It functions, but it isn’t very secure because it doesn’t lock into place. It has slots for extra cords but lays awkwardly on the tank when you use them. Extra cords tend to fall out of the slots and into the water.
The one good thing about this lid is that it has a small opening for feeding, so you won’t have to take it off and risk ruining the perfect placement it took you 10 minutes to achieve. You may want to cover this opening, though, as bettas can be escape artists.
Design
Despite being made of acrylic plastic rather than glass, this tank is sturdy and crystal clear. Unfortunately, it does scratch easily, so you’ll need to take care when cleaning it. This tank is small and doesn’t take up much space.
Pros
Sturdy
Doesn’t take up a lot of space
Filter’s lowest setting is safe for bettas
Filter is large and allows for personalization of filter media
Why we like it: This tank is affordable and its triangular shape makes it perfect for tucking into a corner. The lights are strong enough to support low-light plants.
Items Included:
5-gallon acrylic tank with lid
Filter
Tetra Whisper Bio-Bag Filter cartridge
LED lighting
Filter
The filter included in this kit is quiet and has adjustable flow settings. Unfortunately, even the lowest setting is too strong for bettas and will suck their beautiful fins into the filter. You’ll have to modify it with a baffle or purchase a different filter.
Lighting
The LED light in this tank is a blue-white shade and does not change to any other colors. It works well for lighting up the aquarium, but isn’t as cool as the lights in the Koller Panaview Aquarium Kit and doesn’t have the benefit of mimicking day and night like the lights in the MarineLand Portrait Glass Aquarium. If you are interested in a planted tank, these lights will support low-light plants only.
Lid
The lid on this tank is not great. It’s flimsy and ill-fitting. Rather than snapping into place or being attached in some other way, it just sits on top of the tank. It’s easy to knock into the tank, and if you add a heater (which you should), then it won’t stay in place at all. On the bright side, it does have a feeding hole, so you won’t have to move it once it is in place.
Design
The Glofish aquarium is made of plastic and is completely seamless, reducing the likelihood of leaks. The shape of the tank is actually somewhat triangular, so it fits nicely in corners and is perfect for those who don’t have much space. Because it is made of plastic, it scratches easily.
Pros
Affordable
Fits nicely into corners
Quiet filter
LEDs can support low-light plants
Cons
Filter is too strong for bettas and requires modification
Why we like it: This tank is affordable and made of sturdy plastic. The lid fits well, is attached by a hinge, and has cut-outs that allow you to add extra components like a heater. The color-changing lights enhance the appearance of the tank.
Items Included:
5-gallon plastic aquarium with lid
Filter and cartridges
Color changing LED lights
Set-up instructions
Filter
The filter included with this tank is quiet and the replacement cartridges are easy to find. However, it isn’t the best filter out there. The flow isn’t adjustable and it’s too strong for bettas. This can be solved with modifications like baffles, but you may want to consider replacing the filter as the one included is known for having issues and being short-lived.
Lighting
The lights in this tank are mostly for show as they are color changing LEDs with seven color choices: daylight white, blue, green, amber, aqua, purple, and red. They do look very cool, but they cannot support plant life.
There is also a built-in timer, so you can have the lights on for 1, 2, 4, or 8 hours. However, you have to set it every single day and it can be a bit tricky to use, so be sure to follow the provided instructions.
Lid
All too often, aquarium kits come with less than stellar lids. However, Koller has provided a pretty solid cover for this tank.
It has a hinge on it so you do not have to awkwardly hold it in your hand while you feed your fish or clean the tank. Similarly, the hinge allows for the tank to open in such a way that any condensation will run back into the tank rather than all over your counters.
Though this kit doesn’t include a heater, the lid itself has cut-outs that you can remove to create space for one. The only downside to this is that it leaves a sizable hole that your fish could potentially jump out of.
Design
This tank is made of plastic; it’s sturdy, but it will scratch much easier than glass does. The tank is molded as one piece, so there are no seams and less of a chance of leaks. The shape of this tank also makes it spacious for an adventurous betta.
Pros
Affordable
Lid comes with cut-outs for more customization
LED lights come in seven colors
Cons
Filter is too strong for bettas and may require replacement
LED lights cannot support plant life
Caring For Your Betta
Many people think that bettas are an easy, low maintenance pet to own. However, once you learn more about them, you know that that isn’t exactly the case. While bettas are hardy fish that can survive in less than ideal conditions, proper care will bring out their true nature.
We’re going to teach you all about how to set-up and maintain your tank so that you can give your betta the best possible life.
Initial Set-Up Checklist
Initial tank set-up is pretty straightforward: put in your gravel and decorations, set up your filter and your heater, and fill the tank with water. However, there are some other important aspects of tank set-up that are necessary to keep your betta happy, healthy, and most importantly, alive.
Refer to this short checklist when setting up your tank:
Use a water conditioner to neutralize chemicals in tap water.
Provide lots of places to hide, but avoid plastic plants that can tear your betta’s fins; opt for silk or live plants instead.
Heat water so that it is between 76 and 81°F.
Make sure the tank is cycled (more on that next).
How to Cycle a Tank
Most of us know that we can’t just fill a tank with water and throw the fish in. But many new fish keepers don’t know that they need to “cycle” their tank.
This refers to the process of nitrogen cycling. Your fish produces waste that turns into toxic nitrogen compounds that can kill your fish if left unchecked: ammonia and nitrites. Beneficial bacteria in the tank consume this waste and turn it into nitrates which you remove with regular water changes. The cycle repeats continuously, keeping your fish healthy.
There are several ways to cycle an aquarium, but we’re going to focus on the fishless method. This can take up to six weeks to complete, so you may want to hold off on getting your betta.
Step One: Introduce Ammonia
The first thing you need to do is add ammonia to the water. You can either buy pure ammonia to add directly, or you can use betta food that will produce ammonia as it decays (this takes much longer).
Add about 1 part per million (ppm) of ammonia per gallon. Figuring out how much ammonia to add to get 1 ppm per gallon may take some trial and error, so we recommend using a bucket instead of trying to do this directly in your tank at first.
Step Two: Water Tests
Leave your tank to sit for a few days, and then test the water. Use something like the API Freshwater Test Kit, as test strips aren’t always accurate.
If you notice a decrease in ammonia, this means that your beneficial bacteria are growing! Add more ammonia so that your water is at about 3 ppm per 5 gallons, and continue to test daily, adding ammonia as needed. Eventually, you should see nitrite in the water as well.
After two to three weeks, you’ll likely see nitrite levels drop and start seeing nitrate in the tank. This is a very good sign. Keep testing your water, and you should see nitrite levels drop as nitrate levels rise. When both nitrite and ammonia readings are 0 ppm, your tank is fully cycled!
To be certain, you’ll want to do one final test. Add four ppm of ammonia to the water and let the tank sit overnight. Test it the next day. If ammonia and nitrite read zero with only nitrate appearing in the tank, then you’ll know for sure that your tank is safe for fish!
Step Three: Do a Water Change and Add Fish
Now that your tank is fully cycled, it’s almost time to add your fish. But first, you will want to do a partial water change. Though bacteria in the tank take care of ammonia and nitrite, it’s up to us humans to deal with nitrate.
Remove about 50% of the water from the tank and replace it. Do another test to make sure the nitrate levels are below 40 ppm and ammonia and nitrite are still at 0.
Finally, you can add your fish!
Levels in a Balanced Tank:
pH: 6.5-7.5
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: Less than 40 ppm
Tank Maintenance
If you’ve managed to successfully cycle your tank, then you’re going to want to perform the proper maintenance to keep the process going. There’s nothing worse than having your tank’s nitrogen cycle crash and needing to start all over again.
Water Changes
Water changes are vital to keeping your tank in good health. Depending on the size of your tank as well as your nitrate reading, you’ll want to replace between 10% and 25% of the water each week.
The best way to do this is to get an aquarium vacuum. With a vacuum, you can clean out debris like fish poop and uneaten food from the gravel of the tank, all while removing your 10-25% of water. But don’t dump the water you’ve removed down the drain! You might need it for cleaning.
Cleaning
Any surface in the tank may have beneficial bacteria growing on it, and tap water and soap can kill it. If your bacteria die, the nitrogen cycle could crash, which could lead to dead fish. The best way to keep bacteria alive and well is to clean items with water that you’ve just removed from the tank during a water change.
Feeding and Tank Mates
Maintaining your betta’s environment through tank maintenance is an important part of caring for your pet. Now, we’ll address its needs in terms of feeding and tank mates.
How Much Should You Feed Your Betta?
Many of us have had the horrifying experience of finding our betta laying on his side at the top of the tank, wondering if our lovely fish is at death’s door. A Google search reveals that his illness is a result of overfeeding, an all too common mistake for new betta owners.
A betta’s stomach is about the size of its eyeball. Once you know that, it’s easy to understand why they’re so easily overfed. We recommend buying betta specific pellets and feeding only two to three of them once or twice a day.
Can Bettas Live With Other Fish?
Many people know of the betta’s moniker, “Siamese fighting fish,” and assume they cannot have any tank mates. Male bettas will fight one another, but there are other species they can get along with. Female bettas are less aggressive and can even live with other female bettas in “sororities.”
The following is a list of appropriate tank mates for bettas:
African dwarf frogs
Clown plecos
Cory catfish
Ember or neon tetras
Ghost shrimp
Guppies
Kuhli loaches
Snails
Just remember that the more fish you have, the larger the tank you need.
Final Thoughts
It’s no surprise that bettas are such a popular pet. They’re beautiful and hardy. Unfortunately, there are a number of misconceptions about the type of care they need. But you’ve just finished reading this article, so your betta is going to have an awesome crib with a fantastic caregiver.
