Catappa Ketapang Indian Almond Leaves for Aquariums
Catappa Ketapang, commonly known as Indian Almond Leaf, comes from the tropical tree Terminalia catappa. Dried catappa leaves are widely used by aquarium keepers, particularly in aquariums containing bettas, shrimp and other fish that are commonly maintained in tannin-rich water.
This product contains 70 dried Indian almond leaves for aquarium use. The leaves can be placed directly into an aquarium or prepared separately before the resulting tannin-rich water is added to the tank.
What Are Catappa Ketapang Leaves?
The Terminalia catappa tree grows throughout many tropical and subtropical regions. It is commonly known as the tropical almond, Indian almond or sea almond tree. The leaves naturally change color and fall from the tree as they mature.
After drying, these leaves are commonly used by aquarium hobbyists because they gradually release natural tannins and other plant compounds when submerged in water.
Indian Almond Leaves in an Aquarium
When dried leaves are placed in aquarium water, they gradually begin to soften and decompose. During this process, tannins can give the water a light amber or tea-colored appearance.
This appearance is intentional in many blackwater-style aquariums. Some fish keepers use Indian almond leaves when trying to reproduce an aquarium environment containing natural leaf litter and tannins.
The amount of color produced can vary depending on the size and condition of the leaves, aquarium volume, filtration, water chemistry and how long the leaves remain submerged.
Popular With Betta Keepers
Catappa Ketapang leaves have a long history of use among betta keepers, especially in Southeast Asia. Bettas naturally occur in slow-moving and shallow freshwater habitats that can contain vegetation and decaying plant material.
Indian almond leaves are therefore frequently used as part of a natural-looking betta aquarium setup. They may also provide additional cover and structure inside the aquarium.
Natural Tannins and Water Color
Tannins are naturally occurring plant compounds. As dried catappa leaves soak, these compounds gradually enter the water and may produce the characteristic brown or amber coloration associated with botanical and blackwater aquariums.
The change in water chemistry will not be identical in every aquarium. Factors such as carbonate hardness and the amount of leaf material used can affect the results. Aquarium owners should continue testing appropriate water parameters rather than relying on leaves alone to condition the aquarium.
How to Use Indian Almond Leaves
Inspect and rinse the dried leaves with clean water before aquarium use. Some aquarium keepers place the leaves directly into the tank, while others soak or prepare them separately first.
A dry leaf may initially float. After absorbing water, it will generally become waterlogged and sink. Over time, the leaf begins breaking down naturally.
There is no single quantity suitable for every aquarium. Start conservatively and monitor your aquarium’s water parameters and livestock. Add or replace leaves according to the requirements of your particular aquarium.
Natural Aquarium Appearance
Besides releasing tannins, dried leaves can create a more natural appearance on the aquarium floor. They are especially suitable for hobbyists creating botanical, blackwater or natural-style aquariums.
Because this is natural plant material, individual leaves may differ in size, shape, texture and color. Minor imperfections are normal and do not necessarily indicate a problem with the product.

Important Aquarium Information
These leaves should not replace proper aquarium maintenance. Continue monitoring temperature, pH, ammonia, nitrite, nitrate and other parameters appropriate for the species you keep.
Introduce botanical materials gradually, especially when using them for the first time. Remove material if you notice an unexpected deterioration in water quality.
