How Are They Different From Other Tanks?

Rimless Aquariums differ from other tanks in many ways. The first and the most glaring difference is the way they look. In a normal tank, there are ‘braces’ on the side of the tank walls for support. These rimmed aquariums can also take more water pressure due to their added strength. The rimmed tanks have been so popular so far because they are durable and commonly available. These tanks also have a wide range of options ranging from as small as a 10-gallon tank or even a 100-gallon tank. 

Rimless Aquariums do not have this brace support or frames around their walls. They are plain on all sides and give you a direct view of the fish without the braces obstructing your view. Most Rimless Aquariums do not even have a lid on top! This fact surprises many first-time buyers, but it means that you can observe your fish from every angle without hindrances. 

Rimless Aquariums come in different materials than rimmed ones, but they grow in popularity daily. Not only do they look good, but they also come with many in-built tools to keep your fish happy.

  • Some Rimless Aquariums are suitable for both saltwater and freshwater tanks.
  • Most Rimless Aquariums come with different glass thicknesses for different fish needs.

What To Look For When Buying A Rimless Aquarium

What To Look For When Buying A Rimless Aquarium

When you buy a Rimless Aquarium, the first thing you need to decide on is the purpose. What do you need your aquarium for? Your goal will determine the size of your aquarium. If you have particular fish in mind, you will need to get an aquarium that houses them. If you are using it for aqua-scaping, the size and shape of your aquarium will be different, so on and so forth. 

You will also have to do some research and find out whether your fish will live in saltwater or freshwater and choose the right aquarium for them. 

Some tanks even have a pre-installed sump or added features like a false backing to suit various needs.

When picking out the perfect Rimless Aquarium for you, pay extra attention to the silicone edging of the tank. Look for aquarium brands that have silicone safe and designed. If your new rimless aquarium does not have a proper silicone coating, the glass outlines will look messy. 

You should also research the glass the aquarium uses. Most Rimless Aquariums use a glass called low iron glass. This material is thicker, sturdier, and has more clarity than regular glass. One way to spot a good quality low iron glass is to look for any green-blue tint. If there is no tint to the glass when you view it from different angles, it is low iron. If there is a tint, it is of poor quality, and you should not buy that aquarium.


With Rimless Aquariums being a recent trend, people are often skeptical of their build and durability because it does not have any visible support. Here are frequently asked questions about rimless aquariums, and hopefully, they will clear your doubts.

Why are Rimless Aquariums expensive?

Rimless aquariums are not always expensive. In the products mentioned above, there are multiple options- that are affordable and cheap. Rimless aquariums have a higher price range than rimmed aquariums because the glass quality in a rimless aquarium is higher. Rimless aquariums need extra thick and polished glass to strengthen the walls of the tank. With the high price tag comes high performance.

How big can a Rimless Aquarium be?

Rimless aquariums come in a huge range. The sizes vary from as small as 2 gallons to as big as 100 gallons and above. Usually, rimless tanks have a lot of room and are great options for aqua-scaping and housing community fish. 

Why does a Rimless Aquarium not have a lid?

The main reason why rimless aquariums do not come with a lid is that it makes the tank look ugly. Rimless aquariums are all about the visual appeal and a clear view of the fish inside. Having a lid, limits your sight and dulls the effect of having a rimless aquarium. Some rimless aquariums do have a lid like 8 Gallon Rimless Aquarium With Included LED Light by JBJ.

What holds Rimless Aquariums together?

Rimless Aquariums use thick glass and a high-quality silicone edging to hold the tank together. The reason why it has thick glass is the absence of braces on the side. The silicone edging and the glass ensures that your aquarium will not bend or break. 

Do Rimless Aquariums have any bracing?

Most of the rimless aquariums come without bracing around the perimeter. Some rimless aquariums have regular bottoms with perimeter bracing on the inside. But, the large rimless tanks have a ghost bottom or even multiple layers at times. This increases the stability of the tank. 

How often do Rimless Aquariums leak?

Rimless tanks do not leak frequently. Since rimless tanks are held together by silicone, while buying one make sure that you choose a trusted brand. If the brand is well known and has a good customer base, the chances are that their tanks are of great quality and get tested before they are sold.

How long do Rimless Aquariums last?

Any tank, regardless of whether it is braced or rimless, usually lasts at least five years. The more you care for your tank and maintain the upkeep, the longer it will last. As for rimless tanks specifically, the silicone used to bind the edges together typically lasts for more than 20 years if cared for. Rimless Aquariums are not prone to falling apart easily because the tank’s structural integrity entirely depends on the silicone. Unlike the braced tanks, which have to account for the peak condition of their rims and brackets and lids, rimless aquariums can rest if the silicone is of good quality.


Rimless Aquariums are the way to go if you are a hobbyist or prefer a clean look to your aquarium setup. These tanks have many features, options in shape and size, and their pros outweigh their cons by a long shot. Having a good aquarium will provide you with an immersive experience. As detailed in this guide, there are many options available per pricing and perks, making it easy for you to buy one to suit your fish community. 

Most people have safety concerns when purchasing rimless aquariums, but these are baseless. Most rimless tanks are as safe as rimmed ones. If you get a good quality tank, you will be surprised with the look and the performance.

Getting a rimless aquarium is more a preference than a necessity, but that should not stop you from exploring it.
