What to Look for in the Best 50 Gallon Fish Tank 

Buying a 50 gallons tank is a simple task, but it can get complicated if you don’t know about the things that need to be considered. 

It takes a lot of patience and effort to find the right 50 gallons tank. But we have curated a simple list for you to follow while looking for the aquarium. Scroll down to have a look. 

Type of Fish

Before getting a tank, you should try to decide the kind of fish you want to keep. Generally, both salt and freshwater fish can be kept in the same type of tank. But certain times, aquariums are fit for using only one type of fish.

Tank Size

The very next thing to consider is the size of the tank. Now, it depends on two things, i.e., the size of fish you want to keep and the space available. 

You can start by measuring the available area. Then stick to the measurement and pick a tank accordingly. Do not purchase a tank that exceeds the measured dimension because then keeping it might become difficult. 

Also, if you want to keep a bigger fish, you can choose a rectangle-shaped tank. But if you would like to house small fish, pick any 50 gallons tank. 


Another essential thing to look for is filters. If you want to save yourself from the extra work, invest in a tank kit that comes with a water pump and filter. Without a filter, your fish cannot live in a healthy environment. 

A filter is used for removing pollutants, fish biodata, and chemicals from the tank. If these things are not regularly removed, they can contaminate the water. It can further affect the fish’s health. 


Fish tanks are made of acrylic and glass panels. Now, each of these panels has its pros and cons. For instance, glass aquariums are resistant to chip and scratch. But they are heavy, which makes them difficult to carry. 

On the other hand, acrylic tanks are lightweight. Also, these can be kept around kids and pets. But acrylic panels of a tank can cause leaking. 


While every fish does not require a heater, it’s advised to get a tank that comes with a heater. That’s because when the temperature drops down, the heater protects the fish from freezing. 


Lastly, it’s essential to set a budget before starting your search for a 50 gallons tank. Different brands offer fish tanks at different price ranges. So, if you don’t have a budget, you can end up overspending. 

How to Maintain a 50 Gallon Aquarium 

A sparkling aquarium with beautiful fish swimming in it looks good, but it takes a lot of effort to keep the fish healthy and the tank clean. Here’s how you can do this task. 

  • You can start the fish tank maintenance process by regularly cleaning the filter. Since the filter collects underwater dirt and dust, it can easily get dirty. And a dirty filter cannot keep the tank water clean. 
  • Also, it’s essential to change the tank water frequently. Doing so helps in maintaining a hospitable living condition for fish. But if the water is not changed regularly, it can make your fish sick. 
  • Avoid overfeeding because the leftover fish food settles at the bottom of the tank. When this happens, the water pollution level increases quickly. And in such a situation, you are required to change the tank water even more frequently. 
  • Always check the water’s pH level before adding it to the tank. If the level is abrupt, you can add recommended chemicals to bring it back to normal. Thus, making it fit for fish survival. 

By following these maintenance tips, you can keep your fish healthy and the tank visually appealing. 


A 50 gallons fish tank is ideal for exotic fish keepers who want to take care of large pets. If you don’t like big fish, you can even fill the tank with little fish. 

Among the given 50 gallons fish tank recommendations, the Tetra 55 Gallon Aquarium Kit with Fish Tank is our absolute favorite. This tank comes with a pre-installed heater and filter. 

But if you don’t have any issue finding a heater or water filter yourself, you can consider other options. On the other hand, if you want to purchase a 50 gallons tank other than the recommended options, check the essential factors listed in the post. 

Since a 100 gallon and 50-gallon aquarium is quite big, it can easily house any fish. But the big size might create a problem when it comes to maintenance. However, if you follow the given maintenance tips, you won’t get overwhelmed.
