One of the prettiest sights in an aquarium is a pothos plant surrounding a betta. 

These plants could add to the beauty of a fish tank, and more so if you have Betta in your tank. 

The waxy, heart-shaped leaves of the Pothos can significantly complement the beauty of the small and colorful Betta. 

But the question is, can I put Pothos in my betta tank? True. There are rumors that this may not be an excellent choice for a betta tank. So, read on to see what the truth is.

Can I put Pothos in my betta tank?

You can and you cannot. While some say that it is toxic, there are others who opine that this is one of the most beautiful plants to go into your betta tank. 

And then, there are also others who state that the pothos are not easy to grow, which we have to agree is true. 

So, now the answer to the above question lies up to you. When adding Pothos to your Betta tank, it is essential to ensure that the plant is properly secured and does not pose a risk to the fish. This can be done by using a plant anchor or attaching the plant to a piece of driftwood or rock

Are Pothos Good for Fish Tanks?

Yes, and in fact, they can serve as a good source of biological filtration, 

Besides this, these plants have some long roots, which adds to the hiding space in your fish tank.

How to Put Pothos in Aquarium?

Maintaining an aquarium takes work, and there is a technique for everything. 

This includes adding Pothos into your betta tank. So, here’s how you do it. 

  • First, see that your aquarium is spacious enough to let the leaves grow out of the water. This is a big plant. 
  • Now, ensure the plant is far from any motors that will lead the roots to clog inside your tank. 
  • Then, to make things easier, get an aquarium lid that helps hold the plant in place so the leaves do not fall off. 

All this may seem to be a lot of work but remember that when done right, it can, in the end, give you a beautiful aquarium with a pothos plant. 

How to Hang Pothos in an Aquarium?

Those bright yellow splashes of leaves look the best when hanging, but then there is a way to hang a pothos plant in an aquarium. 

  • First, as stated above, make the necessary room in your aquarium. Remember that this is an aerial plant that needs a lot of space for the roots to spread. 
  • Now, all you have to do is tie the Pothos to the rocks in your aquarium, again far away from any motors. You can even use a hanging basket, but space out the plant. This way, the leaves grow evenly in the basket. 
  • Finally, ensure that you cut nodes to place the plant at a 45-degree angle. But before that, rinse the cut parts. This helps remove soil and other unwanted particles. 

Also, cut the nodes sparingly. The nodes should reach below the waterline. This way, the leaves will look beautiful as they grow above the tank’s waterline. 

Can Pothos Grow Underwater?

Yes, but here is the challenge. Maintaining a pothos growing underwater takes work. Because here, the plant is going to have submerged roots. 

Growing a pothos plant out of water is any day easier than increasing one in the water. However, it is possible to develop a pothos plant under the water. 

More effort is what it takes on your part here. And your efforts will pay off when you receive all those compliments on how beautiful your pothos plant makes your Betta look in the water. 

Is Pothos Poisonous for Betta Fish?

Some say that Pothos are poisonous and not a good addition to an aquarium with betta fish. 

This is mainly because Pothos contain calcium oxalates, which are bad for your Fish’s stomach. 

In other words, these plants can cause stomach irritation and swell your Fish’s stomach. 

In addition to that, it can even be bad for your Fish’s central nervous system. 

Now, all this may or may not be valid. However, if what you read is currently bothering you, know there are various other plants you can place in your aquarium instead of the Pothos. 

If that is a good idea, read on to have a look.
