Our Catappa Tree Leaves (Terminalia Catappa) provide many benefits for tropical fish aquariums. When submerged in water, the leaves will release tannins and tinge your aquarium water in beautiful golden-brown color.  They are perfect for recreating black water habitats.  Additionally, like many other botanicals, they will lower the pH and release other beneficial organic compounds such as humic acids and flavonoids.  These substances are understood to have antimicrobial properties and may also absorb and detoxify other harmful compounds or heavy metals sometimes present in tap water such zinc, copper, and aluminum.  For these reasons, all fish will benefit from the presence of the Catappa Almond Tree Leaves in their habitat.  

Our Leaves are completely natural and free of any pesticides or herbicides.  They are collected by hand after they had fallen from the trees and then they are cleaned and sun dried before being packaged.  They range in sizes from small to medium to large.


You can soak them in fresh water for a few days to let them become waterlogged 


Just rinse them under tap water and place directly in your aquarium. They will float for a day or few before becoming fully waterlogged becoming a functional and aesthetic substrate enhancer


Place them into a filter sock and use them simply as a filter media to help foster "blackwater" conditions in your aquarium.

NOTE: Since these leaves are natural and collected when they had fallen from the trees, each leaf is unique and may look differently from the exemples shown in the picture above.

    I bought these for my betas, as they are found naturally in the betas natural habitat. I have not used them yet. They arrived in excellent condition with no damage. They are much bigger than I thought they would be. They are about the size of my hand, so when I do use them I will only use half of one at a time; therefore, they will last longer.

    I am very happy with the leaves. Large, in good condition, and properly packed. Actually getting them was a bit of a challenge. They weren’t included in my first order and I had to pay for them a second time since Modern Aquarium was convinced they had sent them. At twice the list price it was a quality product that should have cost less.
