In the world of aquariums, few natural additives are as beloved as Indian Almond Leaves — also known as Catappa leaves. These simple dried leaves are packed with powerful benefits that promote health, vitality, and balance in both fish and shrimp tanks.
At Aquarium Plants Factory®, we believe that the best aquariums mimic nature. Indian Almond Leaves are one of the easiest and most effective ways to do just that — bringing natural goodness directly into your water.
Indian Almond Leaves come from the Terminalia catappa tree, a tropical plant native to Southeast Asia and India. In the wild, these leaves naturally fall into rivers and ponds, slowly releasing beneficial compounds that enrich the water and support aquatic life.
When added to aquariums, these leaves mimic natural habitats found in places like the Amazon or Southeast Asian rainforests — environments where many popular aquarium fish and shrimp originate.
Indian Almond Leaves release tannins — organic compounds that slightly lower pH and soften water. This creates gentle, natural conditions ideal for:
Betta fish
Tetras and rasboras
Dwarf cichlids
Shrimp and snails
The resulting amber tint gives the water a natural “blackwater” look — just like in tropical streams and forest pools.
Tannins have antifungal, antibacterial, and anti-inflammatory properties. They help prevent common infections such as:
Fin rot
Fungal patches
Bacterial growth on wounds
They also soothe fish, reducing stress during transport, spawning, or environmental changes.
Aquarium Plants Factory® Tip: Add a leaf or two to new quarantine tanks to help fish acclimate naturally.
Indian Almond Leaves are a favorite among shrimp keepers! As the leaves decompose, they release biofilm and beneficial microorganisms that shrimp — especially baby shrimp — love to graze on.
Benefits for shrimp include:
Easier molting due to mineral support
Increased survival rates for fry
Healthier coloration and shell development
Combine them with dense live plants like Willow Moss or Cryptocoryne Wendtii Green for a thriving shrimp paradise.
The natural tannins and humic acids in Indian Almond Leaves create a calm, soft-water environment that encourages breeding in:
Betta fish
Apistogramma and ram cichlids
Tetras and rasboras
Shrimp colonies
They also act as a spawning site for bubble-nesting species like bettas, providing a secure surface for nests and fry protection.
As the leaves decompose, they provide a mild carbon source that nourishes beneficial bacteria — strengthening your aquarium’s biological filtration system.
This results in:
Stable nitrogen cycle
Lower ammonia and nitrite levels
Healthier, clearer water over time
It’s a simple, natural way to support your aquarium’s ecosystem from the inside out.
Rinse the leaf under warm water to remove dust or debris.
Add 1 leaf per 10–15 gallons of water.
Let it float or sink naturally.
Replace every 2–4 weeks, or when the leaf fully breaks down.
You can also pre-soak the leaf in hot water for 15–20 minutes to release tannins faster and soften it before adding it to your aquarium.
Natural décor: Adds an authentic, rustic look to blackwater aquascapes.
Shrimp feeding supplement: As leaves decay, they provide a slow-release food source.
Breeding tanks: Helps condition soft, slightly acidic water ideal for egg-laying fish.
Medicinal bath: You can steep leaves in warm water to create a tannin-rich “tea” for treating mild fish infections.
Indian Almond Leaves are one of nature’s best-kept secrets for aquarium care. From improving water quality to boosting immunity and supporting breeding, they provide countless benefits in a single, natural package.
Whether you’re keeping colorful bettas, peaceful tetras, or vibrant shrimp colonies, these leaves help your aquatic pets thrive — the natural way.
