Indian almond leaves of the Terminalia catappa tree are especially popular in the betta and shrimp hobby as a natural medicine and water conditioner. They are said to help combat fungus and bacterial problems like finrot, and prevent stress by mimicking the natural habitat.
When placed in an aquarium, Indian almond leaves slowly start to decompose. While this happens they turn the water a yellow or brown color by releasing tannins. These tannins lower the pH and are said to have antifungal and antibacterial properties, which comes in very handy when you have a fish suffering from finrot or when you’re raising vulnerable fry. It also serves as a long time food source for shrimp.
Simply lay the leaves in the aquarium. The effect of the ingredients begins with no further action required and lasts 1 – 3 weeks. Put one leaf (approx. 18 cm long) to 50 – 100 l.
