While it may sound strange to you, adding Indian Almond leaves to the aquarium’s housing sick, soft water, or blackwater fish is a common practice.
Indian Almond Leaves help the immune system of fish, prevent disease, and lessen stress – but how do simple leaves do this?
these dried leaves release tannins, anti-bacterial compounds and other trace minerals into the water, closer simulating the natural environment of most tropical fish. Specifically, tannins lower the PH and make the water a little darker.
Who are they for?
Fish who come from environments with lots of leaf litter will love everything the leaves provide. Shrimp (especially Cardinias) also appreciate them, and baby shrimp and fish fry feed off the Infusoria that grows on the leaves.
Using the leaves:
Leaves will float on the top of the tank for 2-3 days while soaking in water. They will then sink to the bottom. After 2-4 weeks, or when the leaves start breaking apart, the leaves are spent and you can remove them from the tank.
Dosage depends heavily on what you use them for and the water conditions, but a good minimum for pronounced effects is around 1 leaf per 40 liters. You can increase this to up to 1 leaf per 15 liters for fry, quarantine or treating sick fish
