What We Think Is The Best 5 Gallon Fish Tank

Let’s first take a look at our top pick that we personally feel is the best 5 gallon tank. This particular option comes with pretty much everything you need to get started and have a nice little aquarium setup.

Marineland Portrait Aquarium Kit

If you are looking for a nice looking 5 gallon fish tank, the Marineland Portrait Aquarium Kit is a decent option to consider for several different reasons. Let’s go over all of the features and aspects that come with this option so you can know just a little bit more about it (you can check the current price at Amazon here).


The Marineland Portrait Aquarium Kit comes with a decent filtration unit. It features an advanced 3 stage filtration system located behind a black filtration panel. This filter engages in all 3 major types of filtration including mechanical, biological, and chemical, filtration.

It will remove all manners of impurities and toxins from the water to help your fish be happy and healthy. Also, it comes with all of the filtration media you need to get started.

This filter is more than powerful enough to turn over the water in the tank several times over every single hour. It does actually have an adjustable flow rate so you can match the flow to the needs of your aquarium inhabitants.

We do like how the filter is located behind a blacked out panel because it helps preserve the nice look of this particular 5 gallon aquarium.


The Marineland Portrait Aquarium Kit comes with an LED light bar for illumination and some plant growth. It features both white and blue LED lights.

The white lights are great for the daytime and plant growth, while the blue lights are awesome for some slight nighttime moonlight simulation. It’s a great way for your plants and fish to feel at home!


This aquarium is fairly easy to access. It comes with a hinged lid, to which the light is attached to. All you have to do is open the top up like a lid and you have access to the interior of the aquarium. At the same time, this also makes it fairly easy to gain access to the filter for easy maintenance.

Look & Build

This aquarium looks very nice in our opinion. The square shape of it with the clear sides and corners offers you an unparalleled view of the interior. Everything that can be clear on this aquarium is clear, which is something we really like.

We do also like how this aquarium is fairly small and easy to manage, making it ideal for beginners and children alike.


  • Good size for beginners.
  • All in one kit.
  • Good lighting system.
  • Advanced filtration.
  • Looks really sleek.
  • Easy to access and maintain.


  • Not the most durable around.

5 Gallon Aquascape Tips

If you have a 5 gallon aquarium, it means that you have a fairly small tank with very limited room to work with.

Here are some great 5 gallon fish tank aquascape tips so you can make the most out of the limited space at your disposal.

Plant Growth Rate

One of the most important things to pay attention to here is the type of plants you want to put in the aquarium, specifically in terms of the growth rate.

It is recommended to get aquarium plants with slow growth rates, so they don’t grow too fast, and therefore require minimal maintenance.

Plant Size

On that same note, you do also want to pay attention to what maximum size your aquariums plants will grow to.

In a 5 gallon tank, you really don’t have much room, so smaller plants are the ideal way to go.


Speaking of aquarium plants, another big aquascaping tip here has to do with their placement. The largest plants should be placed at the rear, with the smallest plants at the front.

This will help create the impression of a larger space, and it won’t cause big plants to eat up valuable real estate. Carpeting plants are always good plants for small aquariums.

Commonly Asked Questions

What Are The Best Fish For 5 Gallon Tanks?

Just keep in mind that the rule of thumb is to have no more than 1 inch of fish per gallon of water in the tank. This is generally the minimum tank size requirement for any fish.

Here are some fish which you could put in a 5 gallon tank, comfortably.

  • 2 to 3 neon tetras.
  • 1 to 2 normal goldfish.
  • 1 Betta fish.
  • 2 danios.
  • 2 to 3 guppies.

Should I Get A 5 Gallon Aquarium Kit, or Just The Tank?

Well, this really depends on what your needs are and how much money you are looking to spend.

On one hand, getting the tank alone is great if you have enough cash to purchase all accessories separately, especially if you want to customize your setup and get very specific lights, filters, and all of that other stuff.

However, this way is usually not all that cost effective. If you want to make life a lot easier, you don’t want to spend too much cash, and you aren’t too picky about the specific equipment you get, or even if you have kids that want a fish, by all means go for an all in one kit.

How Many Betta Fish Can I Put In A 5 Gallon Tank?

Realistically you can only put 1 single betta fish in a five gallon fish tank. Now, betta fish do only grow to around 2.25 inches long, so based on minimum tank size requirements (1 inch of fish per gallon of water), you could technically fit 2 of them in a 5 gallon tank but please don’t do this.

You need to keep in mind is that the 1 gallon per 1 inch of fish rule is an absolute minimum, not the ideal level. The ideal is more like 2 gallons of water per inch of fish.

Even if you are working with the minimum tank size requirements, betta fish are ferocious fighters and they really do not get along well with each other, so having 2 of them together, even in a 10 or 15 gallon tank can be a challenge.

Does A 5 Gallon Fish Tank Need A Filter?

Yes, absolutely a 5 gallon tanks needs a filter. The more fish you have in the tank, the better of a filter you will need. In fact, most would agree that you actually need a better filter for a smaller tank than for a larger one.

Things like ammonia will build up faster in a smaller tank, compared to a larger tank, and therefore it also requires a high quality filter to keep that ammonia down, as well as other unwanted substances too.
