One thing Bettas love is laying on leaves but these leaves do so much more. They are said to help combat fungus and bacterial problems like finrot, and prevent stress by mimicking the natural habitat of the betta. There are a a few different ways to use Indian almond leaves; the easiest 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 more quickly. 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 actually appreciate it if you don’t remove the leaves, as they feed on the decomposing remains.
So many benefits can come from using these leaves and these ones are huge, so why not give them a try? I found my bettas definitely appeared healthier after using them for a while.
