What Are Indian Almond Leaves?

Indian almond leaves are leaves that come from the Catappa tree (hence why they’re also known as Catappa leaves). They come from Asia, Australia, and Africa, and they’re often used in aquariums for their medicinal properties and to change the aesthetic of the tank.

What Are The Benefits Of Indian Almond Leaves?

There are actually a few different benefits to Indian almond leaves, which is why they’re so popular amongst hobbyists!

Antifungal & Antibacterial

One of the best reasons to add Indian almond leaves to your tank is because of their antibacterial and antifungal properties. The tannins in leaves actually protect plants from fungus and bacteria, so once they leech into the tank, the same benefits will enter the water!

However, just remember that while they do have these benefits, they’re still not a substitute for proper maintenance of your tank.

They Provide Hiding Places

Another reason that Indian almond leaves are great for your fish tank is that they provide plenty of hiding places. If you have timid fish or bottom dwellers, adding Indian almond leaves will help break lines of sight and give them areas of the tank they can go to feel safe!

Protecting Fry

On a similar note, if you’re breeding fish, then Indian almond leaves are going to give the fry somewhere to hide as well! And on top of this, they also feed the infusoria in your tank, which fry will eat!

They Decompose Slowly

If you’re going to put Indian almond leaves in your tank, they’re going to be there for a while. It takes Indian almond leaves about 2 months to decompose completely, and because of how cheap they are to buy, it won’t be hard to constantly keep some in your tank!

They Will Provide Food To The Animals In Your Tank

If you have herbivores and omnivores in your tank, such as shrimp, snails, or algae eaters, then adding Indian almond leaves is going to be a great way to make sure they’re getting enough food as well!

And the more the leaf starts to decay, the more you’ll see them getting eaten up!

It Will Help Create A Black Water Tank

If you like the look of black water tanks, then adding Indian almond leaves to the tank is a great way to get this look! So if you’re housing blackwater fish, make sure you’re keeping Indian almond leaves in the tank!

They Lower pH In The Tank

Lastly, Indian almond leaves are also going to lower the pH in the tank as well. So if you know that the pH in your tank has become too high, adding a couple of Indian almond leaves to the tank can help slowly lower it again over time!

And because it’s happening slower, you don’t have to worry about a sudden parameter change affecting your fish.

How To Prepare Indian Almond Leaves For Your Aquarium

If you plan on adding Indian almond leaves to your aquarium, then here are the best ways to add them to your tank!

  • To add them to your tank, one of the easiest ways is to just add the leaf to the tank and let it sink to the bottom, then every month or two, take it out and replace it with a new one!
  • If you don’t like the look of large leaves, you can also shred them into smaller pieces which can then be added to the tank as well!
  • And lastly, you can also make an extract from the Indian almond leaves! To do this, boil some water and add it to a jar with 1 or 2 Indian almond leaves. Now, all you need to do is keep the water in the fridge, and every couple of months just pour a small amount into your tank!

How Many Indian Almond Leaves Should You Add Per Gallon?

Generally, you should add about 1 medium-sized Indian almond leaf to your tank for every 10 gallons of water. If your tank is smaller, you can just cut the leaf in half. However, if you add more than one, it shouldn’t cause a problem in your tank; just keep an eye on the water parameters.

Is It Possible To Use Too Many Indian Almond Leaves?

If you add too many Indian almond leaves to your tank, then the worst side effect is that the tank’s water will become very dark. If the water becomes too dark, then you’re going to have a hard time seeing your fish, and in rare cases, plants in the tank may have trouble photosynthesizing.

However, if the tank water does become too dark, all you’ll need to do to remedy the situation is remove the Indian almond leaves from the tank and perform some water changes!

And lastly, adding some activated carbon to your filter will also help strip the remaining tannings from the tank! Just remember that it will take time for the water to return completely back to normal!
