Betta Tank Guide

There aren’t many fish as beautiful as Bettas which is why they are some of the most popular for at-home aquariums. Because of their territorial nature, they are often best kept in a separate tank which is why a lot of people opt for a convenient betta tank. 

They also make an excellent first-time option for someone dipping their toes in the world of fish ownership but some products make life easier than others. This is why we have created the following buyer’s guide. by the end of it, you’ll be able to find the right product to get you started. 

What To Look For In A Betta Tank

A Complete Kit

Unless you have a few bits hanging around from a previous aquarium then you are going to need a starter kit. Some people prefer not to buy them as they like to upgrade the filter or other included items but anyone starting will appreciate having everything they need from to get started. 

The Placement Of Accessories

Your filter might need to be attached to the side of the tank or you might purchase a product that keeps everything out the way. Some product has a separate area that keeps the tank clear for unobstructed views. 

LED Light

Being able to see your Betta at night can really add to the appeal of keeping fish. A reliable LED light should not consume a lot of energy but provide a pleasant ambiance. Some products have a blue/white light option so you can give your tank a moonlight effect at night. 

Hood and Canopy

Although they are small, it is not uncommon for Betta fish to jump. This is why the best Betta tanks come with hoods to keep the fish secure. It also keeps other pets such as cats away. The canopy is another feature that the better products offer as it can provide easy and fast access to the fish when it comes to feeding or a spot of cleaning. 


Some people like a traditional, longer tank whilst a portrait design can be pleasant to look at. Also, some brands make acrylic betta tanks so you can enjoy a crescent design. 

Easy Set-Up

Some Betta tanks are easier to use than others and because a lot of them are tailored towards beginners, you will find that the majority of products are easy to set up. Some have built-in filters that do not require installation but the downside to these is that if they break, they can be difficult to fix.

Can A Betta Fish Be Kept Alone?

You will often find Betta fish kept alone and although the tank might look sparse and the fish might have a lonely look to it, the fact is, they are so territorial, their preference is to be kept alone. This is why a lot of Betta tanks do not have such a large capacity. 

How Big Is A Betta Fish?

They vary in size, but not by a huge amount. Betta fish tend to be around 1 – 5 inches long and can breathe out of an organ called a labyrinth. This allows them to breathe from the surface and makes them pretty adaptable compared to other breeds. 

Can You Keep Male Bettas Together?

A lot of experts might recommend against keeping two male Bettas in the same tank. The reason being, they are very territorial and can be aggressive. This is why many people find dead Bettas in their tank and are also why keeping multiple females is a wiser choice. A male Betta is best kept alone whereas a female is more likely to tolerate coexisting with others. 

What Do Bettas Like In Their Tank?

If it is a male, then not other Bettas! All joking aside, Bettas like to have a place to hide so keeping multiple plants around can help them feel safe. With floating plants, in particular, they can enjoy the opportunity to stay out of sight for a while. 

What Is The Best Temperature for Betta Tanks?

Although most Betta tank starter kits don’t include a heater, if you live in a warmer climate that doesn’t have a cold winter then you might not need one. Still, remember that a tank needs to be around 78 – 80 degrees F. If you cannot maintain this temperature without a heater, then it is important to purchase one before you allow your Bettas into their new home. 

Betta Tank: Acrylic Vs Glass

There are benefits to both and whilst your Betta won’t notice the difference, you might have a preference.

Although they are heavier, glass tanks tend to be more affordable and resistant to scratches. However, the downside is they are more likely to crack and even shatter in extreme cases.

An acrylic betta tank is good because it can come in different shapes. Just be careful when setting up and handling an acrylic tank as they can scratch easily which might impact your view of your Betta fish.

Benefits of A Betta Tank

There are many reasons why it is a great idea to keep fish, so having a Betta tank can be an excellent idea for many reasons. The most common being the following:


Even the sound of flowing water has been shown to relax those who are stressed. For a less anxious household, keeping Betta fish can be a great idea.

Increased Productivity

Ever wondered why fish are often kept in office spaces? Well, a lot of people believe that keeping fish can help boost productivity through its relaxing benefits that help workers to operate with a clear mind.
