Promotes healing naturally Adds tint to water Great for betta fish Catappa leaves, also known as Indian Almond Leaves, come from the Terminalia catappa tree. They have chemical healing properties, which may naturally help fight off mild bacterial, fungal, or parasitic infections. Therefore, these leaves are great for many different types of livestock including bettas, shrimp, community fish, and more.  You get 20 Catappa leaves per package. Leaf size ranges from 4 to 7 inches, typically. In nature, Terminalia catappa leaves will fall into rivers and other bodies of water and will tint the water a rich brown 'tea' color as they break down. This is due to chemical compounds found within the leaves called tannins. For this reason, Catappa leaves are often used in blackwater setups to achieve deeper brown colored water and for leaf litter on the bottom. For shrimp, replace the leaf when it has been mostly consumed. For Bettas and other fish when using the leaves for healing, use them until they stop turning the water brown. We use 1 leaf per 5 gallons. ***Due to the natural nature of this product we cannot guarantee it will look exactly as pictured***
