Buyers’ Guide

What do I look for when buying a 5 gallon fish tank? 

There are several factors you can keep in mind which will help you make an informed decision when buying a 5 gallon fish tank. Since we’re talking exclusively about 5 gallon fish tanks in this post, the size of the fish tank is not something you’ll have to consider or think about. The remaining factors are: 

  • Durability 

When you’re buying a fish tank, you should observe it thoroughly and judge the material its body is made out of in order to ensure it will last you a long time. 

You don’t want to keep investing in a new fish tank every other year so make sure you get one that’s built to last. You need to ensure that the tank you’re getting will be able to withstand the pressure that will be exerted by the water poured into it. If it’s made from a flimsy, frail glass or acrylic material, it could crack and lead to leaks.

  • How easy is it to Set Up

If you’re an amateur hobbyist or are looking to get your children into the hobby of fish-keeping, we strongly recommend you get a fish tank that is easy and even fun to set up. If you get a fish tank that’s too complex in its installation process, your children might lose interest midway. 

  • How Easy is it to Maintain

If you’re a busy person that doesn’t have a lot of time to devote to the maintenance of your fish tank, you might want to get one that doesn’t require a lot of it. 

How do I set up a 5 gallon fish tank? 

First off, you need to choose the location of the fish tank. A 5 Gallon fish tank is small in size and not that heavy so you can get away with not investing in an aquarium stand and just having it on a desk or tabletop but make sure that the base is sturdy and will be able to support the weight of the tank. 

Add the gravel to your fish tank, mount and connect all the electrical equipment such as filters, heaters and air pumps. Add the water and add a dechlorinating and conditioning agent to it. 

Most people have the hang of it up to this point but what a lot of people don’t do is cycle their fish tank. 

Cycling refers to the process of growing beneficial nitrifying bacteria inside your fish tank which aid in the process of biological filtration by neutralizing dangerous toxins. This usually takes about 4-6 weeks. 

Once this is done, you can add fish to your tank. Keep an eye on the water conditions such as pH, temperature, etc for the next few hours to make sure they are stable. 

Congratulate yourself on a job well done. You’ve just successfully set up your 5 gallon fish tank.

What are the different types of 5 gallon fish tanks? 

5 Gallon fish tanks are a small piece of equipment that can be used in a number of different ways. The different types of 5 gallon fish tanks are: 

  • Breeding Tank 

A 5 gallon fish tank is the perfect size that can be used as a breeding tank for different species of fish. Some fish are timid and will only mate privately and it’s a great idea to invest in a 5 gallon fish tank that will allow your fish to breed away from the distractions of other fish.

  • Species Tank 

There are many exotic species of fish out there that require a specific set of conditions in order to grow and thrive. A 5 gallon fish tank is a small environment that’s easily controllable and can work perfectly for you. You can easily control the conditions of a 5 gallon fish tank so they are ideal for whatever species of fish you choose to host in that tank.

What are some benefits of a 5 gallon fish tank over other tanks? 

A 5 gallon fish tank has a couple of advantages over other tanks that may be larger than it. 

Firstly, since a 5 gallon fish tank doesn’t have a large footprint and doesn’t weigh too much, you can easily place it on your desktop or a table or countertop and you’ll see that its attractive colors and appearance will definitely tie your room together. This also means that you won’t have to invest in a separate aquarium stand. 

Having a small 5 gallon fish tank will also mean that you won’t have to invest a lot of time cleaning it. Larger aquariums demand a lot of time and effort to be cleaned but this is not the case when it comes to a 5 gallon fish tank.

How do I perform a weekly water change in my 5 gallon fish tank? 

You can perform a weekly water change by replacing 10-15% of the water in your aquarium. 

Firstly, siphon out the water into a bucket. Make sure there’s ample water in your fish tank for your fish to swim comfortably. 

Add tap water to a clean bucket and add your dechlorinating and water conditioning agent to it. Mix it up well and let it sit for a few hours. 

Add the water gently into your aquarium so as not to disturb your fish. 

Frequently Asked Questions

What are some suitable dimensions for a 5 gallon fish tank?

Most 5 gallon fish tanks are more horizontal than they are vertical. Some conventional dimensions of a fish tank are a length of about 18 inches with a width of 10 inches and a height of 8 inches. 

While this is the convention, you definitely get a lot of products that push boundaries when it comes to the dimensions of a 5 gallon fish tank. For example, the product that’s number one on our list has a shape that defies all conventions when it comes to the shape of fish tanks. 

What other equipment do I need for my 5 gallon fish tank? 

A 5 gallon fish tank usually comes in the form of aquarium kits. While these kits are marketed in the fashion so that they claim to have “everything you need to get started”, you may want to take their claims with a grain of salt. 

Here is a comprehensive list of all the equipment you need to successfully run an aquarium. If your 5 gallon fish tank doesn’t have one of these features, you might want to invest in one separately: 

  • Lighting
  • Filter
  • Heater
  • Air pump 
  • Dechlorinating agent
  • Water conditioning agent 
  • Water testing kit 
  • Net for removing large waste particles

What’s a suitable number of fish I should have in my 5 gallon fish tank? 

The golden rule of thumb that is normally used in the aquarium world is that you should have 1 inch of fish for every 1 gallon of water. Seeing as how we’re talking about 5 gallon fish tanks, you should not have more than a total of fish that make a combined length longer than 5 inches. 

It is important to note that when we’re talking about the length of the fish, we mean the maximum lengths that they will grow up to be. Do not judge the length of your fish by how big they are when you buy them. Properly research to find out how big they can get and get your number of fish accordingly.

What kinds of fish should I keep in my 5 gallon fish tank? 

Small to medium-sized fish when they are full-grown are a great option to have in your 5 gallon fish tank. If you want to have an individual fish in your 5 gallon fish tank, a Betta is a great fish to have as they are energetic and have beautiful, long, vibrant tails that are a treat to watch. 

Other fish you can have in your fish tank include Clownfish, Puffer fish, Gourami, Crayfish, Livebearers, Paradise fish, Killifish, Loaches, etc.

What are some of the most trusted aquarium brands when it comes to 5 gallon fish tanks? 

There are all kinds of different brands cashing in on the rising popularity of fish-keeping as a hobby but the most trusted brands which you should buy from are listed below. 

  • MarineLand
  • Fluval
  • Marina
  • Koller Products
  • Penn Plax
  • GloFish
  • Tetra

We’re not saying other brands can’t be good but these are some whose products we test regularly and they have been consistent in terms of quality and effectiveness.

How often should I perform a water change in my 5 gallon fish tank?

A 5 gallon fish tank is a relatively smaller aquarium when it comes to aquariums that people have in their homes and considering this fact, a 5 gallon fish tank actually becomes dirty a lot quicker than larger aquariums. 

This makes sense when you think about it because since it is hosting a smaller body of water, when your fish excrete waste products into it, it will become more concentrated with waste and debris a lot quicker than a larger aquarium. 

Thus, we suggest that you perform small water changes after every 3-4 days combined with a slightly larger water change each week. Finally, you should perform a 25-50% water change every month that should be accompanied by a deep cleaning process as well. 

Final Verdict

5 gallon fish tanks are a great thing to have in your room that can really elevate its appearance and appeal. It’s important to get a product that will not lose its beauty over time and will be easy to maintain. 

After months of experimenting, we have to give the crown to the MarineLand Portrait Glass LED Aquarium Kit. Its unique design takes up a lot less space compared to its competitors, it’s easy to clean and it is extremely durable.
