Product details

CeramicNature Catappa leaves allow you to care for your fish, shrimps and other aquarium inhabitants in a natural way. The Catappa (also known as Ketapang-, Almond-, Terminalia- or sea almond leaves), serve as a water purifier for freshwater aquariums at the same time.

The substances contained in the Catappa leaves (tannins) stimulate the compaction of the mucous membrane. This densification of the mucous membrane protects the skin and enhances the colours of the fish. Catappa also contributes to increased well-being and vitality.


When placed in the aquarium, catappa leaves will slowly decompose, releasing tannins that turn the water yellow or brown. These tannins can lower the pH of the water and are thought to kill bacteria and fungi, which is useful for fragile fish. The dark colour of the water dampens light and mimics the natural habitat of many fish, which can help reduce stress. This is why many aquarists use the leaves in their tanks.


The CeramicNature Catappa leaves are a suitable product for the natural care of aquarium water. Moreover the Catappa leaves are a beautiful decoration for your aquarium or terrarium.

The leaves do not need to be processed before they can be used. The dry leaves sink after a few days (1-2) and will fill up with water after which they sink to the bottom. After this the active ingredients will be released. This process takes two to three weeks, after which you can add a new leaf to the aquarium. The leaves can be left in the aquarium as they also serve as a popular snack. Shrimps, catfish, L numbers, etc. love the leaves and scrape them dry.


The leaves are picked directly from the tree, cleaned, smoothed and then dried in the sun. If you keep the Catappa leaves dry, they can be kept indefinitely.
