Catechu Bark ( Acacia Catechu ) Sealed With Srting T-Bags




As with Indian Almond Bark, if your fish comes from a habitat where Indian Almond leaves and other plant debris regularly falls into the water and decompose, your fish will be happier in that environment so trying to mimic it in your aquariums is strongly recommended. Leaves and bark that fall into the water release many different compounds, from dyes to trace minerals, and animals living in the water adapt to having all those different compounds readily available. If your fish comes from the type of environment described above, Catechu Bark is one way of simulating black water condition which is the natural environment for most tropical fish.

Like Indian Almond Bark, Catechu Bark is high in natural tannins which accounts for its astringent effect and has been proved to harden the scales of bettas as well has sharpening their teeth. Acacia Catechu is also known as cachou, cutch, cashoo, Terra Japonica, khoyer or Japan earth).


The Catchu Bark T-Bags can be placed directly into the tank or put into the filtration system. Alternatively, you can put the bags into a cup and add boiling water, leave to cool. The water in the cup will have the appearance of strong tea by the time the water cools and can be added to your aquarium. This will leave a strong brown dye that will tan the water slightly (to a clear amber) and provide a very natural stream-bottom look to your aquarium. The Catechu Bark extract can also now be poured into plastic or glass bottles, sealed and stored in fridge or somewhere dark and cool.
