Blackwater - CaribSea BETTA LEAF™ AND JUNGLE LEAF™ Indian or Tropical Almond leaf aka Catappa or Ketapang leaves




Indian or Tropical Almond leaves, also known as Catappa or Ketapang leaves are used by fish breeders worldwide to recreate the natural environment of tropical fish and invertebrates such as bettas, tetras, corys, angelfish, discus, freshwater shrimp and other species that come from soft-water jungle or rice paddy habitats. The natural tannins released by these unusual leaves are touted for their many health and biological benefits, and the “soft cover” created by these leaves give your tropicals shelter similar to what would be found in their native ecosystem. These leaves can also be used as a forest floor substrate for arthropods, tropical reptiles and amphibians. Betta Leaf™ and the somewhat larger Jungle Leaf™ are the perfect addition to your tropical environment.

How and when to use Indian Almond Leaves

Indian almond leaves, also known as Catappa leaves of the Terminalia catappa tree in Asia and are especially popular in the betta, gourami, discus and shrimp hobby as a natural medicine for fish and natural water conditioner. The leaves are said to help combat fungus and bad bacterial problems like fin-rot and also prevents stress by mimicking the natural habitat. When placed in an aquarium, the 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 anti-fungal and antibacterial properties which comes in very handy when you have a fish suffering from fin rot or when you’re raising vulnerable fry. The dark coloration of the water is considered unsightly by some aquarists, but it actually mimics the natural habitat of many fish species all over the world! If you’re trying to mimic nature, then use the leaves. If you want to help create a healthier environment for your fish naturally without the use of harmful chemicals, seriously USE THE LEAVES! It’s the natural and correct thing to add to any freshwater or brackish aquarium.

Adding a few leaves to a quarantine tank with a sick fish can help speed up the healing process! There are many breeders who have stopped using fish medications altogether and treat sick fish with nothing but Indian almond leaves and clean water.

There are a a few different ways to use Indian almond leaves; the easiest way is to just place them in the aquarium and wait for them to do their job. The more you add, the darker the water gets. You can tear the leaves up if you want the tannins to release quicker. Once the they start decomposing you can take them out or replace them, but it’s also fine to wait for them to be completely decomposed. Shrimp will feed on the decomposing remains of the leaves.

When you’re dealing with fish/invertebrates that prefer soft, acidic water, Indian almond leaves can also be great for stimulating breeding. The tannins released by the leaves help create water conditions that are similar to those in the natural habitat of the fish, which means ideal breeding conditions. If you’re trying to get your bettas or Crystal Red shrimp to breed, adding a few Indian almond leaves to the breeding tank can speed up the process! You can also make your own blackwater extract, which is a concentrated version of stained water. This is done by taking a very large amount of Indian almond leaves, boiling them in a pot of water and letting them soak for multiple days afterwards. You only have to add a small amount of the extract to your aquarium to get that blackwater look that will keep many species of fish much more happy!.
