How to Choose an Acrylic Aquarium?

There are some essential features that you need to consider before buying an acrylic aquarium. We have listed down all of them below for your convenience so that you can easily make the right buying decision according to your needs and requirements.


Most of the acrylic aquarium reviews tend to forget about this core aspect when making a choice. First of all, you have to decide what you want to achieve with your acrylic aquarium. A small reef tank is something completely different from the one that is designed for dwarf shrimp.

For each aquarium design, you will need different types of plants. Depending on the tank, you will also have to consider whether you need snails for algae growth or not. Lastly, you have to decide between a saltwater aquarium or a freshwater type.


Size is going to be a detrimental factor based on the available space. There are different sizes available, ranging from 3 gallons to over 20 gallons. You need to pick the correct dimensions based on the open space in your room.

Moreover, with a larger tank, you can also place more fish and invertebrates in it. For instance, a 10-gallon tank is not suitable for 10 goldfish but it is for 100 dwarf shrimps. Before buying your tank, think about which fish species you’re going to put.


Shape may be more important than size based on where you are going to place the tank. Perhaps you want it to be on your wall, in which case it needs to be a half-moon shape.

If you want to put it on your desk, consider a tank shape that provides a view from all angles, especially if the desk is placed at the center of the room. Also, the fish need an uninterrupted swimming space. Place all the plants and decorations either in the middle of the aquarium or on one side.


If you are looking for an aquarium that comes with all the equipment for filtration, heating, or other display purposes, your tank will be larger. Pick the right lighting system for the kind of display that you’re after.

For beginners, your tank must have all the essential equipment to get it going right from the start. Various customization options are available, but you need to understand how they all work for the best results.


Acrylic is a kind of plastic, so it is created by joining different pieces sealed together. Some models are made in a mold so it is understandable to see some seams at the top and the bottom. If a tank you got comes with seams, they need to be cleaned and sealed to prevent leakages.


Rims are not necessary for an aquarium if it can hold the water on its own. But these rims also function as braces, so they help make your aquarium more resistant to water pressure. Putting a lid on your aquarium creates that extra water pressure. With these rims, your aquarium will have the necessary strength to handle the water well.


If you don’t have a clear picture of the tank design that you want yet, find a model that allows you to conveniently customize its features. Brands like BiOrb offer customization options. They also manufacture equipment that works well with all aquarium models from the brand.


The best acrylic aquarium that money can buy is the Tetra Crescent Acrylic Aquarium. It has a lightweight construction and comes with a 5-gallon capacity. The aquarium is simple to install, and you can conveniently place it wherever you want. It has a powerful filtration system, and it provides you with an unobstructed view from all angles.
