Acrylic aquariums are less prone to chipping and breaking compared to glass tanks. This means they are safer if you have children and pets roaming around your house. An acrylic aquarium is safe for both fresh and saltwater usage. However, there is a drawback to acrylic: it scratches very easily. So your aquarium may start getting scratched and look ugly with time. This also means that if you get algae in your aquarium, you will have to completely change the water since you cannot scrape them off the aquarium wall as it will leave scratches.

However, you should note that it does not come with a filtration system or a pump. Some users complain that the lighting housing that comes with this tank also does not fit the tank as it overhangs the edge a bit.

Rimless aquariums lack the support of rims, so they are made with thick glasses and high-quality silicone. The silicone is meant to provide the support needed to hold the pressure of the water. Rimless aquariums are usually made with low iron glass, translating into crystal clarity. Unfortunately, low-quality glasses with high iron typically have a green tint that does not give a good view of what's happening inside the aquarium tank.

It is also easier to access the upper portion of the tank of rimless aquariums, which makes them the perfect choice for nano reef tanks.

Regular tanks are less expensive compared to rimless aquariums. These tanks are mass-produced and usually have a top and a hood. One of the caveats with traditional aquariums is that most of the time, they do not let its user connect to a distinct light source. However, it is easier to find large-rimmed tanks because the rim can support excessive weight and pressure.

Both rimless and regular aquariums have their pros and cons. Rimless aquariums could be the obvious choice for most people, given their aesthetics. However, since rimless aquariums are costlier than regular aquariums, some people might not be able to afford them.

How to Buy a Rimless Aquarium

It is essential to know how to buy a rimless aquarium. You want to avoid being stuck with an aquarium that is too complex to build. On the other hand, you want to avoid being stuck with a very basic aquarium when you require a sophisticated one. You would also want to avoid buying an aquarium that will leak soon and endanger your fish and shrimp. Therefore, we have compiled a simple guide to finding the perfect rimless aquarium for yourself.


Determine your budget:

The first thing you should do before looking for any product is to determine your budget. Ask yourself how much you want to set aside for your rimless aquarium. The amount of money you are willing to spare on your aquarium will help you filter out aquariums so that you can focus on what you can afford.

However, you should note that expensive brands do not always mean they are the best. Similarly, cheaper brands do not mean that they are not good in quality. Nevertheless, you can find a good-quality aquarium tank with a reasonable budget.

Saltwater and freshwater tanks:

If you want a freshwater aquarium, you should not spend extra on one made of salt water. However, suppose you are unsure and might use it for salt water. In that case, it is better to go for saltwater aquariums suitable for all water types. The ones listed below are ideal for all kinds of water and do not leave a dent in your wallet.

Tank features:

It would be best if you also looked at what tank features you want to be included with your tank. Some brands only offer you a tank, while others provide a kit with all the essentials. If you are a beginner, you should look for brands that offer a complete kit and are easy to start with. The kit should include LED light and filter, at the very least,

Determine how many fish you want to keep in your tank:

Determining how many fish you want to keep in your tank will help you decide the overall size. If you wish for an aquarium for one fish or a few shrimps, you would need a small tank with a three-gallon rimless aquarium capacity. You will be best served with a medium to a large tank with 5 to 10 gallons of capacity if you need a tank for multiple fish and shrimp. Also, note that you should be able to set aside adequate space for your tank if you go for the larger tank. Another thing to note is that the larger the tank, the more challenging it is to set up and maintain it.


Frequently Asked Questions

Are rimless aquariums worth it?

Rimless aquariums are worth it for those who prioritize aesthetic appeal and unobstructed viewing but may require extra precautions and maintenance to ensure the fish's safety and the tank's durability.

Rimless aquariums have gained popularity due to their sleek and modern appearance, allowing for a minimalist and unobstructed view of aquatic life. However, without the rim to support the tank's weight, extra care must be taken when selecting a suitable stand and ensuring the tank is level to prevent any cracks or leaks.

Additionally, with no rim to contain water splashes, regular cleaning and maintenance are necessary to prevent water damage to surrounding furniture and flooring.

What is better, a rimmed aquarium or a rimless one?

Choosing between a rimmed aquarium and a rimless aquarium ultimately depends on the personal preferences of the owner and the type of fish or plants they plan to keep, as rimless tanks provide better viewing angles and easier access for maintenance. In contrast, rimmed tanks provide added structural support and prevent water from spilling over the edges.

Why are rimless aquariums expensive?

Rimless aquariums are expensive due to the use of thicker glass to compensate for the lack of support from a rim, higher labor costs for a more precise and polished finish, and a limited market demand for this specific style of aquarium.

Do rimless tanks leak?

Rimless tanks can potentially leak if not properly sealed and maintained, as the lack of a frame leaves the edges of the tank vulnerable to cracking or damage.

Can you recommend another brand?

Lifegard Aquatics Crystal Aquarium is another brand worth checking out on Amazon. However, it couldn't make it on our list, given the mixed reviews.
