How to Divide a Betta Tank?

There are many different ways to divide a betta tank. You can use a ready-made divider, or you can create your own using household items.

If you want to use a ready-made divider, then there are many different options available on the market. You can find dividers made from plastic, acrylic, or glass. They come in a variety of shapes and sizes, so you should be able to find one that fits your tank perfectly.

If you want to create your own divider, then there are many different ways to do this. You can use a piece of acrylic, plexiglass, or glass. You can also use a plastic storage container or mesh. The key is to make sure that the divider is sturdy and will not fall apart when your betta starts swimming around.

Here’s a step-by-step guide to dividing your betta tank:

Step one: First, you need to decide what kind of divider you want to use. If it is a ready-made option then great! If not, then pick out something that will serve the same purpose.

Step two: Next, take everything apart so that there are no sharp edges on any part of the dividers or the tank. This is important for your betta’s safety!

Step three: Now, measure the size of your tank and the size of the divider. If there is too much space then your fish will get bored and may become aggressive towards the divider.

Step four: Once you have measured everything, it’s time to start assembling the tank! Start by adding some water and then place the dividers in the desired position. If you are using a plastic storage container or mesh, then make sure that you secure it to the sides of the tank with aquarium-safe glue or silicone sealant.

Step five: Once the dividers are in place, it’s time to add the fish! Make sure that you introduce them slowly and monitor their behavior. If they seem happy and swimming around then great! If not, then you may need to re-think your divider.

How to Make a DIY Betta Tank Divider?

If you are going to build the divider itself, you will need to be very careful. The materials that you use should not have any rough edges or sharp points, and they should fit securely inside the tank.

You will need:

  • Tank
  • Canvas mesh 
  • Binder report spines
  • Tank sealant

Use the binder spines to attach the canvas mesh to the tank. Make sure that there are no gaps between the mesh and the walls of the tank, as this will allow fish to escape.

Once it is attached, you can apply some sealant around the edges so that it is watertight. This will keep your betta safe and secure! You may not need the sealant, but it’s a good idea if you have two male bettas that you really need to keep apart from each other.

Semi Divided Betta Tank

You may also want to consider a semi-divided betta tank. This is perfect for those who want to keep their fish together, but at the same time, give them some space to swim around in their own territory.

You can create a semi-divided betta tank by using a divider that is not completely enclosed. This will allow your betta to swim back and forth between the two sides of the tank.

Many betta owners create a divide with tall tank decorations and plants. This will provide ample hiding spots for your betta to rest, and they can even retreat into a cave.

Are Divided Tanks Good For Bettas?

Divided tanks are mainly good for bettas because they are territorial fish that like to stake out their own area. Using a divider means that they can have their own space without having to compete with other fish for resources.

Just make sure that the dividers are sturdy enough to keep them apart, otherwise, you could have a very territorial and aggressive fish on your hands!

It is not recommended that you keep two males together in the same tank because they will become aggressive towards each other and fight until one of them dies. If you want to keep more than one betta, then a divided aquarium might be perfect for your needs!

The only downside of using a divided betta tank is that it can be more difficult to clean. You may even need to remove the divider every time you want to scrub the sides of the tank.

How Tall Should a Betta Tank Divider Be?

The divider should be a few inches higher than the tallest fish in your tank. This is to ensure that your betta cannot jump over the divider and escape.

If you already own betta, then you may have seen them jump for yourself. They do this when they are excited or if they really want to get to something, like another area of the tank!

They could even jump up in the air and accidentally end up on the other side. This is why it’s important to make sure that the divider is tall enough to keep them in one place.

Is There More Risk of Disease in a Divided Betta Tank?

Yes, there is a greater risk of disease in a divided betta tank. This is because the fish share the same water with each other and it is easier for them to spread their illnesses.

This means that if one betta gets sick, then the other fish are at risk too. You will need to be extra vigilant about keeping the tank clean and changing the water frequently to prevent any diseases from spreading.

If one of your fish does become ill, then you will need to separate them from the other fish and treat them in a quarantine tank.

Every time you buy a new fish or tank decoration, you will need to place it in quarantine for 30 days before introducing it to the rest of your tank. This is just for added protection and will help you avoid any diseases that could have been caught by another fish during transport.

The Importance of Monitoring a Divided Betta Tank

It is important to monitor a divided betta tank closely because the dividers can be a tempting target for your fish. If they start attacking the divider, then it could lead to some serious damage.

If you see any signs of aggression or stress, then you should remove the dividers and give your betta some space. This will help to keep them calm and healthy.

Regularly check the divider for small holes or cracks to ensure that your betta cannot escape the tank.

In case of emergencies, it can be a good idea to keep a quarantine tank close by. This will allow you to temporarily house your fish in case they get injured or sick. In fact, I think this tank is a necessity for all owners of multiple fish.

Conclusion

In conclusion, a divided betta tank is a great option to consider if you want to keep more than one betta fish. Just make sure that the dividers are sturdy and safe for your fish.

Betta fish are territorial, so don’t keep two males in the same tank or they will fight until one of them dies. If you want to keep more than one betta then a divided aquarium is perfect!

Remember that cleaning your dividers is not as easy as using an all-in-one option. You may have to remove them every time you want to clean the tank. Make sure that they are sturdy enough for your betta fish.
