Catappa Leaves – Indian Almond Leaves 10-pk

Catappa (Indian Almond) Leaves for Aquariums

(Terminalia catappa)

Catappa leaves, also known as Indian Almond Leaves, are one of the most trusted natural aquarium additives used by aquarists worldwide. Harvested from the tropical Indian Almond tree, these dried leaves are rich in beneficial tannins and organic compounds that help recreate natural blackwater conditions.

They are especially popular for bettas, shrimp tanks, breeding setups, and soft-water species.

Key Benefits

• Naturally releases tannins and humic acids

• Helps lower pH in soft water setups

• Creates natural blackwater conditions

• Supports immune health with mild antibacterial and antifungal properties

• Reduces stress and encourages natural behaviour

• Promotes breeding and fry survival

• Provides grazing surfaces for shrimp and biofilm feeders

As the leaves break down, they release beneficial compounds that may help protect fish from minor bacterial and fungal issues while creating a more natural and comfortable environment.

Ideal For

• Bettas

• Shrimp tanks

• Tetras and rasboras

• Discus and angelfish

• Breeding tanks

• Fry grow-out tanks

How to Use

• Rinse lightly before use.

• Add directly to the aquarium (1 leaf per 20–40L depending on size and desired effect).

• Leaves will float initially, then sink over 1–3 days.

• Replace every 2–4 weeks or as needed.

Water may turn a tea-coloured tint — this is normal and beneficial.

Important Notes

• Best used in soft to moderately soft water.

• Monitor pH if using in smaller tanks.

• Safe for fish, shrimp, and most freshwater species.

Catappa leaves are a natural, eco-friendly way to enhance aquarium health while mimicking wild tropical environments. A must-have for serious aquarists looking to provide optimal conditions for their fish and shrimp.
