 2. Marineland Portrait Aquarium.


The first of such tanks on our list of 9 best 5-gallon tanks for betta fish is the Marineland Portrait Aquarium. One of the things you look out for when buying goods on an eCommerce platform such as Amazon is the number of positive reviews that a particular product has been able to garner.

It has the highest number of positive reviews on Amazon. What this means is that it is one tank that you can safely invest your money in. It has an estimated rating of 4 stars from more than 900 buyers, that says a lot.

The only reason why it’s not topping the list is simply that it’s a high tank rather than a long one. Yes! we told you to always opt for length and not height, but the Marineland Portrait tank is an exception to such rules.

In a high tank, your betta will have a hard time swimming to the surface. However, this tank is useful if you plan to house some other tank mates with your betta. But in a 5 – gallon tank, doing such is not recommended.


The Pros.

  • Yes! we pointed out the fact that it isn’t the ideal shape for your tank pet, but on the positive side, it lets you decorate the betta’s home more stylishly. You can try out vertical decorations in this tank.
  • The Marineland’s compartment has a compartment designed in the back that lets you hide both filter and your heater. Hiding the water heater and filter is a good way to keep your betta tank clean.
  • Interestingly, the tank comes with a filter. This isn’t one of those ‘get a gift’ promo that gives low-quality gifts all in the name of giving gifts. By the way, this is not a gift, but it is just a kit that comes with the tank. The filter is quite silent. Also, you can adjust the pace of the current coming from the filter, making it comfortable for your betta.
  • It features an LED light that lets you clean your tank with ease. You can easily flip the light aside while you clean the entire tank. By the way, these LED lights come in daytime and nighttime mode which is pretty cool.

The Cons.

  • One of the downsides to this kind of tank is that it doesn’t come with a water heater. Getting a heater separately is the right thing to do.
  • As interesting as it is to have a separate compartment for a tank, it can be pretty frustrating when trying to clean it.

3.The Fluval Spec V Aquarium Kit.

Being cheap or having different features aren’t necessarily the best things to look out for when buying a tank for your betta. Being efficient at housing the betta with ease and doing that effectively is one thing you hardly see in tanks.

The Fluval Spec V is one of those tanks that effectively houses your betta hassle-free. The tank comes with some great features nevertheless. No reason why it’s on our list of the 9 best 5-gallon tanks for betta fish

LED lights are preinstalled in the tank. The tank also comes with a portable filter which lets you maintain the clean state of the water. One of the things you’ll like about this tank is its size.

It is one of those tanks that prove that length triumphs over height. It has a wide shape which means your betta will have more horizontal space to swim.
So, why is this tank on our list of 9 best 5-gallon tanks for betta fish?

The Pros.

  • The Fluval Spec V comes with a separate compartment that lets you hide the heater and filter more compactly.
  • The tank is designed in such a way the upgrading or replacing its equipment can be done with ease which is quite rare. Most tanks don’t let you add an upgrade or replace the damaged equipment.
  • The tank comes with a portable and efficient filter and functional LED lights that add to the overall beauty when you have your betta in it.

The Cons.

  • On the downside, the filter preinstalled in it can be pretty powerful for some certain bettas. If this is the case with your betta, you should get a pre-filter sponge which lets you reduce the flowing current.
  • You will need to cover it with a lid to avoid water leakage. Being an open tank, the chances of the water evaporating is high, which is why you’ll need to get a lid or tank cover.

4. Marina LED Aquarium Kit.

The Marina LED is not a portrait tank like the Marineland Tank, but being wide is enough reason to be on this list. With its wide space, you can add lots of plants and decorations to make your betta really feel at home.

The tank has a 5 – gallon space that is huge enough to house different plants, substrates, and other things you need to create an ecological home for your plant.

It comes with different items that make things easy for betta owners to start creating that betta life for their fish pet. The tank is great for starters due to its easy-to-use design and features. Speaking of coming with things to get betta owners started, you’ve got betta feed in its kit.

The tank also features a portable filter that does have the 3 stage filtrations (chemical, mechanical, and biological filtration). With this filter, you can easily get rid of debris, pollutants, odor, and the toxic ammonia in the tank.
This is why it’s one of the 9 best 5-gallon tanks for betta fish out there:

5. Fluval Edge 6-gallon Aquarium.

Another Fluval on our list of 9 best 5-gallon tanks for betta fish is the Edge 6 Gallon Aquarium. Just as the name suggests, it is quite bigger than a 5-gallon tank. But we still had to add it to our list because it’s great capabilities.

It comes with some interesting kits. It has a stylish look that will add to the overall beauty of the betta’s home. What do we think about the Fluval Edge 6-Gallon Aquarium?

The Pros.

  • One of the things you’ll like about the 6-gallon tank is the filter. Even though it looks slightly big, it will be perfect in the tank, wicking out the dirt effectively. As long as the filter is on, you have one less thing to worry about.
  • Just because you have a filter in it doesn’t mean there is no extra space for gravels, decorations, plants, and of course, a media cartridge.
  • The tank is quite stylish, and will in every way redefine the look of any room it is kept in.
  • The LED light system also features the daytime and nighttime mode.

The Cons.

  • Speaking of some of the things that could be improved upon, the LED light is one of such. The light isn’t efficient to grow plants in the tank. That is why we recommend upgrading the light to the 42 LED light system which is way better.
  • It’s easy to say that the tank does the job effectively, being overly expensive will make you rethink on getting one at all.
  • The tank has a small opening which makes cleaning a little bit difficult.

6. Penn Plax Curved Corner Glass Aquarium.

Another glass tank on our list is the Penn Plax Curved Corner Glass Aquarium. if you want to get into the fishkeeping industry, you need to always look out for every unique tool that will help your betta grow the way it needs to.

If that’s the case, the Penn Plax tank is a perfect choice. Unlike what you have with some other tanks, it has a unique look which makes it more interesting.

It comes with an aquarium kit including a filter (built-in), and an LED light. But what are the benefits of owning one of these tanks?

The Pros.

  • The big deal here is that the tank comes with a lid. Now, most tanks often come without a lid or any form cover. For this tank to come with a lid, it is pretty much a big deal. The lid helps to cover the tank top completely. Just as we’ve mentioned in the previous articles, we’ve shared with you, bettas are very active and tend to jump out from their tank if and when it’s not covered. With this tank, that’s one less thing to worry about (in our previous article, we also talked about the other ways to prevent your betta fish from jumping out).
  • The tank also comes with a mat that lets you place the tank on it, that way the furniture it’s standing on or close to it won’t be damaged.
  • It has a unique shape and overall styling which is great if you want to beautify both your home and that of your betta fish. if you want you to wish to opt for is a standard tank shape coupled with an extra then this is one tank you should get.
  • It comes with a filter that is very effective when it comes to making the water in the tank stay clean most of the time. And all of these for that price? It’s really worth it.

The Cons.

  • One of the downsides to this tank is the fact that it comes with lights that are not effective. This light doesn’t come with an on or off switch. This means that you have to move it aside if you want to open the tank top/lid. So, if you are going for this tank, then you should get a better light. This doesn’t take anything away from why it’s on our list of 9 best 5-gallon tanks for betta fish.
  • One more thing, the filter it comes with is good. But in the long run, you should invest in a better filter. The filter it comes with does provide mechanical, chemical, and biological filtration; it’s still definitely going to be a good idea if you invest ins something much better. It doesn’t have to do the 3-way filtration.
