Dried mango leaves (Mangifera indica) are a fantastic, natural botanical for freshwater aquariums, highly prized for their antibacterial and antifungal properties. As they break down in the water, they release beneficial tannins that create a natural habitat, reduce stress for fish, and provide a vital food source for shrimp.
Water Conditioning
They release tannins and humic acids which gently lower pH, soften water, and tint it a beautiful amber color (perfect for blackwater setups).
Disease Prevention
Rich in polyphenols and mangiferin, they act as a natural antimicrobial agent to help heal wounds, strengthen immune systems, and protect fish eggs from fungus.
Biofilm & Food
As the leaves soften, they cultivate a layer of biofilm that is a primary food source for fry (baby fish), shrimp, and snails.
Territorial Breaks
Broad mango leaves provide excellent visual barriers for aggressive or territorial species like dwarf cichlids and betta fish.
Adding collected or purchased leaves to your tank is a simple process:
Source Safely
Only use completely dried, brown leaves that have fallen from the tree naturally. Ensure they are free from pesticides, fertilizers, and roadside exhaust.
Boil First
Boil the leaves for 5–10 minutes. This sterilizes them to eliminate parasites or pollutants and softens them so they sink to the bottom of your aquarium much faster.
Add to Tank
Place 1 to 2 leaves per 30 to 40 litres of water.
Maintenance
The leaves will slowly decompose over 1 to 2 months. You can leave the leaf skeletons in the tank as they continue to provide shelter and biofilm, or replace them as they dissolve.
