What are the best betta fish tank decorations to use in your aquarium?

Although natural decorations are very beautiful and functional, artificial decorations can also be a good choice for those looking to decorate their aquarium more simply. This means that the accessories placed in the aquarium must never restrict the swimming of the fish or hinder the circulation of the water.


When there aren’t any plants in a tank, it seems to be empty all of the time. They not only help to make the whole arrangement appear more natural, but they also serve as hiding places for your betta fish. When opting for plants you will then need to choose whether you prefer live or artificial ones.

Live plants

It is beneficial to have live plants in your water since they increase the amount of oxygen in the water. They are also less likely to harm your betta, and they will increase in size, perhaps filling up more space in your tank if you let them to. 

The disadvantages are that they need more effort to maintain and that, if you want your tank to appear less wild-looking, you may need to trim them more frequently than usual. Java moss, anubias, and anacharis are all excellent plants to employ as a starting point for your garden.

Fake Plants

Plastic or silk plants are used to create fake plants. One of the most significant advantages of artificial plants is the fact that you will not have to care about them in any way. In general, you can just place them in the aquarium and leave.


Another basic popular decoration you can see in many aquariums is driftwood. It is a great focal point and oftentimes you can use it to anchor plants too.

This structure will also give hiding spots and swimming passages for your betta, as well as hiding spots for any other fish you may have in your aquarium. However, there are certain disadvantages to using driftwood. It is possible that the driftwood will reduce the pH of the tank water over time, and if you keep it for an extended length of time, it will begin to disintegrate. 

If you plan on include driftwood in your tank, make sure to purchase it from a merchant rather than utilizing natural materials. Also, remember to clean extremely well before placing the driftwood in your tank.

Marimo Moss Balls

Marimo moss balls are a wonderful decoration that also assists you in keeping your tank clean. If you carefully set them at the top of the tank, they will float there for a short period of time. However, if you prefer them at the bottom, you can just fully submerge them.

Marimo Moss balls are balls of algae that is continually growing. However, you shouldn’t be concerned about them covering your tank with algae because they are not likely to do so. Not only will Marimo moss balls provide a beautiful addition to the appearance of your tank, but they will also serve as a toy for your betta to play with as it moves about the tank.


Other awesome natural additions to aquariums are some rocks and rocky constructions. They can be found in the natural environment of the betta fish. You should make certain that when you add rocky structures to your tank, they will not collapse on top of one other. 

Rocks also offer the additional benefit of providing an excellent environment for algae growth. It is also vital for the oxygenation of the water that algae are present. Furthermore, if you have bottom feeders and algae eaters in your tank, they will really like these! 

Always remember that if you’re going to utilize rocks, it’s best to get them from a trustworthy source rather than just using rocks you’ve discovered. Some rocks may also release some chemicals throughout time, usually calcium-based rocks. These substances can become toxic to your betta fish will alter some other water parameters, such as pH.

Artificial Decorations

You can also opt for using artificial decorations in case you do not want to worry about other lives in your tank and their requirements. Houses, skulls, caves, divers, and shipwrecks can be easily found in aquarium and pet stores worldwide and will make awesome visual additions to your tank.

When you are using fake decorations, look for ones that have a large number of holes so that your betta may swim freely between the decorations. These structures will keep your fish entertained and will also provide hiding spots and resting areas for the betta fish.

What to look for and avoid in decorations?

Sharp edges are one of the most important things to avoid while building a house. They have the potential to cut the body of your betta fish, and depending on the sort of ends and tail they have, they may very swiftly destroy them.

Avoid anything made of metal

To begin, you should refrain from placing any metal ornaments in your tank. While they may appear to be in good condition at first, they may gradually rust with time. 

Besides the fact that this will be exceedingly hazardous to both your betta fish and the water in which they live, if your betta fish cuts himself on the rust, he may get sick.

Avoid Shells & Coral gravel

Shells and coral gravel should be avoided in your tank unless you need to control low pH. These substrates are rich in calcium, and thus, this would cause a release of the chemical in the water over time.

Avoid glass

You should also avoid using glass if possible. In most cases, glass on its own does not pose a concern. If, on the other hand, it smashes into your tank, you will have a lot of difficulty removing all of the fragments.

As aggressive and surly as your betta comes off, it is important that it feels safe in its tank. Bettas are inherently shy and like to hide in the wild, therefore you must ensure that it has the ability to do so in its aquarium. This is especially critical in the early stages of a project. 

And when you provide your betta fish with a hiding area, it will behave in the exact opposite manner to what you expect. You will notice that it will swim more freely and organically in its tank now that he feels more secure in there.

They entertain your betta fish

Another motive you’ll need a lot of decorations is to keep your betta interested while you’re decorating. Increasing the density of plants, ornaments, and other decorations in your tank will result in your betta spending most of his time investigating.
