This keeps your Betta fish happy and healthy because they have fun playing and hiding.

Not only is it a safe space for your Betta fish to hide in, but it is also definitely something that can help them relieve boredom and have a nice time in their fish tank.


Rock formations or good chunky rocks can be a great addition to your Betta fish tank.

They are also found in their natural habitat, which is why your Betta fish are going to enjoy them.

However, you have to be extremely careful while adding the rocks to your water tank.

You must make sure that they do not fall and hurt the Betta fish or are not placed in an area where they can easily move and cause some damage.

Make sure they are fixed in a spot where they cannot move or fall further downward.

A good way to use these rocks is to anchor some life plants around them so your Betta fish can use them to swim in between.

Some rocks also encourage algae growth which may not look the best but are extremely beneficial for the oxygen levels of your water tank.

Besides Betta fish, they can be beneficial for any bottom feeders you may have in the tank.

Leaf Hammock

A leaf hammock is an ideal decoration and resting place for your Betta fish. As a species, they are naturally familiar with huge water bodies such as swamps.

They are used to having a lot of space for them to move around, which is why they require at least five gallons of water.

Regardless of their space to swim, Betta fish always stay towards the surface of the water, which is why a leaf hammock can give them a nice spot to relax under.

It acts as a covering on a small part of the water tank. This gives them access to both dark and light environments.

They can go in either, depending on their mood and needs.


Driftwood is a staple decoration for several Betta fish tanks.

Not only is it a great focal point, but it is also used to anchor other plants that you might add to the Betta fish tank.

It can also be used as a hiding place or something to swim through for your Betta fish’s enjoyment.

However, using driftwood as a decoration item for your Betta fish tank has some ramifications.

As time goes on, it may lower the pH value of your tank water because it will naturally begin to rot.

If you do plan on using driftwood for your tank decoration, make sure you buy a treated one from a seller instead of a natural piece of driftwood that you found.

Thoroughly clean it before adding it to the tank no matter where it came from so that it does not pollute the water in the tank.

Avoid Shells and Coral Gravel

Even though it makes perfect sense to add shells to your Betta fish tank, they can be harmful in the long run.

Since both coral gravel and shells have a high calcium level, they slowly emit it into the water over time.

This allows the pH level of the water tank to rise, which may be upsetting for your Betta fish.

You can also opt for fake ceramic seashells just for the aesthetic.

Things To Remember:

  • No sharp or rough edges
  • Stay away from toxic materials that can mess with water quality
  • When you purchase an item online or from the store, make sure you thoroughly wash and disinfect it so that it doesn’t transfer any bacteria or diseases to your fish tank
  • Try not to add glass products to your tank, as they can crash and shatter
  • With every cleaning cycle, make sure you thoroughly wash all the tank décor as well before placing them back in the tank
  • Don’t overcrowd your tank with décor pieces because it may interfere with your Betta’s swimming space

The Bottom Line

There are so many options for you to choose from over at Amazon, but it is important to remember to always check the decor items for sharp edges and toxic materials.

There’s nothing wrong with spoiling your fish with decoration items and toys, but make sure you also provide them with the basics such as high-quality food, a controlled water environment, and an ample place to swim around before anything else.
