Acrylic aquarium vs Glass aquarium

If you’re looking for a new aquarium, you may be wondering whether to choose an acrylic or glass tank. Both materials have their unique benefits, so it can be tricky to decide which one is better.

This blog post will do the leg work for you and compare these two widely-used aquariums for you to make an informed decision when purchasing the right tank.

What are acrylic aquariums?

Acrylic aquariums are fish tanks made from a single piece of clear acrylic plastic. Acrylic aquariums have several features that make them ideal for freshwater and saltwater fish tanks.

Advantages of acrylic aquariums

  • Acrylic is much lighter than glass, making it easier to move and transport.
  • Acrylic is non-porous, so it does not harbor bacteria and algae. This means that you won’t have to scrub your tank as often, and your fish will be healthier.
  • Acrylic aquariums are also safer for your fish. If an acrylic aquarium breaks, the pieces will be smaller and less sharp than glass, so your fish will be less likely to be injured.
  • Allows drilling as it is more flexible

Disadvantages of acrylic aquarium

  • Acrylic is more susceptible to scratches and other marks. It can be a problem if you keep fish known to be particularly active or aggressive.
  • Another downside of acrylic aquariums is that they are generally more expensive than their glass counterparts. Acrylic is a more difficult material to work with and requires more specialized equipment and expertise.
  • Requires gentle and careful handling when cleaning the tank to avoid scratching its surface.

What are glass aquariums?

Glass aquariums are among the most popular types of aquariums on the market today. Glass aquariums are usually made with either tempered or untempered glass.

  • Tempered Glass is stronger and less likely to shatter if it breaks
  • Untempered glass is cheaper but more fragile.

Most people think of glass aquariums as big, bulky, and expensive. However, there are many different types and sizes of glass aquariums available.

Advantages of glass aquariums

  • One of the biggest advantages of glass aquariums is that they are very durable. glass is a very strong material and can withstand a lot of wear and tear.
  • Another advantage of glass aquariums is that they offer a clear view of your fish. This is because glass is completely transparent, unlike other materials such as plastic or metal.
  • Glass aquariums also allow you to see the different levels of the water column, which can be useful for monitoring the health of your fish.
  • Allows comfortable and easy cleaning without scratching

A glass aquarium can also be a great way to show off your fish to friends and family. Glass aquariums are much more aesthetically pleasing than other types of tanks, making a room look more inviting. If you are looking for a way to make a statement in your home, then a glass aquarium is a good choice.

Disadvantages of glass aquarium

  • One of the biggest disadvantages is that they are heavy, making it difficult to move around.
  • They are pretty durable, but not as durable as an acrylic aquarium. Also, a glass aquarium is not as good at ressisting scratch as an acrylic one.
  • Does not allow drilling

Acrylic aquarium vs glass: which is better?

If you happen to scratch your glass aquarium, it will be more visible than a scratch on an acrylic tank.


Acrylic aquariums are also durable and shatterproof, more so than its glass counterpart. So, suppose your tank falls or is hit by something. In that case, it is less likely to break and hurt anyone in the process.


When it comes to durability, acrylic wins again. Acrylic is much more resistant to impact than its glass counterpart.

If you accidentally drop your acrylic aquarium, it is less likely to break than a glass one. It is less likely to shatter or crack, making it a safer option for homes with children or pets.


When it comes to cost, glass aquariums are typically cheaper than acrylic tanks. However, this is not always the case. It depends on the size and style of the aquarium you are looking for. Overall, glass tends to be less expensive than acrylic.


In terms of appearance, there is no clear winner. Glass aquariums have a classic look. In contrast, acrylic ones can appear more modern. It comes down to personal preference.


Glass is often clearer than acrylic, and its clarity is constant through time.

Some types of acrylic are also as clear as glass; however, they tend to turn yellowish as time goes by.
