Indian Almond Leaves x10

Indian almond leaves, also known as Catappa leaves, offer several benefits for fish and shrimp in aquariums, including natural pH lowering, antifungal and antibacterial properties, and a food source. They also create a natural, darkened water appearance, promoting a sense of security for sensitive species.

Here's a more detailed look:
1. PH Lowering: Indian almond leaves release tannins and other organic compounds that naturally lower the pH of the water. This is beneficial for species that prefer soft, acidic water, such as many types of shrimp, snails, and certain fish.
2. Antifungal and Antibacterial Properties: The tannins in Indian almond leaves have antifungal and antibacterial properties, which can help protect fish and shrimp from illness and promote healing.
3. Natural Food Source: As the leaves break down, they become a source of food and beneficial bacteria for fish and shrimp. Shrimp will also feed on the biofilm and algae that grows on the leaves.
4. Natural Appearance and Stress Reduction: The tannins in Indian almond leaves darken the water, creating a natural-looking environment that can reduce stress in fish and shrimp.
5. Benefits for Specific Species: Indian almond leaves are particularly beneficial for sensitive species like:
Shrimp (Caridinas, Neocaridinas), Betta fish, Axolotls, Corydoras, Plecos, and Otocinclus.
6. How to Use:
You can add whole leaves to the aquarium, or you can boil them to extract the tannins for a more concentrated solution.
The leaves will gradually decompose, releasing tannins into the water.
You can also use the leaves as a food source for shrimp.
Betta Botanicals offers resources on how to properly use and prepare Indian almond leaves for aquariums.
7. Cautions:
Too many leaves can cause excessive tannins and dark water, which may not be suitable for all species.
Some aquarists have reported issues with shrimp dying after adding Indian almond leaves, so it's best to start with a small amount and monitor the tank.
