The Marineland Portrait Aquarium Kit is an option worth considering if you want a good-looking 5-gallon aquarium for your fish. So that you have a better understanding of this alternative, let’s go over all of the features and elements that come with it.


The filter that is included in the Marineland Portrait Aquarium Kit is rather good. A three-stage filtering system is hidden beneath a black panel. This filter uses mechanical, biological, and chemical filtering methods.

Clean, wholesome water for your fish is what this does by filtering out any and all harmful substances. In addition, it has everything you need to begin filtering water right away.

This filter is so effective that it may cycle through the tank’s water many times an hour. A variable flow rate allows you to tailor the water movement to the specific requirements of your aquarium’s residents.

The fact that the filter is hidden away behind a blacked-out screen is a good touch that will help keep the 5-gallon aquarium looking as nice as possible.


The LED light bar and plant growth media in the Marineland Portrait Aquarium Kit are great additions. In addition to the standard white LEDs, it also has blue ones.

The white lights are ideal for plant development during the day, while the blue lights are fantastic for simulating the moonlight at night. It’ll make your aquatic pets and houseplants feel right at home!


The aquarium is not too difficult to get to. The light is mounted on the lid, which may be opened and closed using the hinge. It’s as simple as lifting the cover to gain access to the aquarium’s inside. And it also makes it simple to get to the filter when it needs to be cleaned or replaced.

We think this aquarium is beautiful. The square design, with its transparent sides and corners, provides an unobstructed view of the inside. The clarity of the aquarium is excellent.

The three-stage filtration system included in the GloFish Aquarium Kit is quite conventional and effective. Although it’s not the most powerful or efficient filter available, it uses all three of the most common filtering processes to constantly provide fresh, clean water.

Most of the filtering media is already a part of the package. It’s hardly the most sophisticated filter ever, but it performs the job well enough. At least it mixes up the tank’s contents numerous times each hour.

Examine and Construct

The aquarium is given greater depth and aesthetic appeal by the tank’s rounded front. It gives the impression of greater size than it actually has. In most cases, a crescent aquarium is the term used to describe this particular form of aquarium.

Advice for Creating a Beautiful Aquascape with a 5-Gallon Aquarium

The 5-gallon aquarium is a tiny tank with limited space.

Making the most of a little area? Here are some excellent aquascape recommendations for a 5-gallon fish tank.

Growth Rate of Plants

The development rate of the plants you intend to place in the aquarium is one of the most crucial factors to consider.

Choose slow-growing aquarium plants if you want to spend less time tending to them.

Dimensions of the Plant

In a same vein, it’s important to consider how large your aquarium’s plants may go.

Since a 5-gallon tank doesn’t provide much area, it’s best to stick to smaller plants.


Another important consideration when aquascaping an aquarium is where to put the plants. Put the tallest plants in the back, and the shortest ones up front.

This will provide the sense of more room, and it will prevent giant plants from taking up useful real estate. Carpet plants are excellent choices for any size aquarium.

5-Gallon Tanks: Frequently Asked Questions

Can you recommend some fish species suitable for a five-gallon aquarium?

Remember that 1 inch of fish per gallon of water is the general rule of thumb for aquariums. All fish should have at least this much space in their tank.

Please find below a list of fish that might do well in a 5-gallon aquarium.

Only a few neon tetras, maybe three.

  • 1 or 2 healthy goldfish
  • Single Betta Fish
  • 4 centimeters
  • 1 to 3 betta fish

When deciding on a 5-gallon aquarium, should I get a whole kit or just the tank itself?

Well, that relies entirely on your requirements and budget constraints.

On the one hand, if you have the means to personalize your setup and get extremely particular lights, filters, and the like, buying the tank alone is a fantastic option.

The downside is that this approach is generally rather pricey. If you’re looking for a simple solution, don’t want to spend too much money, and aren’t choosy about the precise equipment you acquire, or if you have kids who want a fish, then an all-in-one kit is the way to go.

I have a 5-gallon tank, however I was wondering how many betta fish I could keep in there.

Generally speaking, a five-gallon aquarium is too small to house more than one betta fish.

Since betta fish only reach a maximum size of 2.25 inches, you could theoretically keep two of them in a 5-gallon tank if you followed the minimal standards (one inch of fish per gallon of water).

Remember that the 1 gallon per 1 inch of fish guideline is the bare minimum and not the optimum level. Two liters of water for every inch of fish is the sweet spot.

Betta fish are fierce fighters and do not get along well with each other, so housing more than one in a tank of any size, even if it’s only 10 or 15 gallons, might be difficult.

Can You Go Without A Filter In A 5 Gallon Fish Tank?

A filter is necessary for a tank of any size, and a 5-gallon tank is no exception. There should be more fish in the aquarium before upgrading the filter. The general consensus is that a smaller tank requires a more powerful filter than a bigger one.

The buildup of ammonia and other undesirable chemicals is exacerbated in a smaller tank compared to a bigger one; as a result, a high-quality filter is essential for maintaining healthy water conditions.


There are a lot of alternatives out there, but the following are some of the best 5-gallon fish tanks in BestForPets‘ (bestforpets.org) opinion and research, so we hope our reviews will help you discover your ideal 5-gallon tank MarineLand Portrait is our top recommendation .
