Dulce Bark (Pithecellobium Dulce) is a rich source of tannins and other phenolic compounds beneficial for both fishes and shrimps.

​

Similar to the Indian Almond Leaves and Indian Almond Bark that Bettawan offer, if your fish comes from a habitat where 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 Barks 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, Indian Almond Bark is one way of simulating black water condition which is the natural environment for most tropical fish.

 

The Dulce Bark tannins inhibit the growth of various fungi, yeast, bacteria and viruses. Dulce Bark is used worldwide by Betta owners that like to fight their fish.

 

Betta’s brought up in Dulce water are known to send their opponents into shock if they bite a Betta not brought up in the Dulce water. The opponent stops moving in a state of shock allowing their fish to attack with ease.

* Put 1 bag of Dulce Bark into 5 Litres of clean water.
