-
Improved Health:Tannins have antibacterial and antifungal properties that can help prevent diseases like fin rot and fungal infections.
-
Stress Reduction:The calming effect of tannins in the water reduces stress, leading to more active and colorful bettas.
-
Enhanced Immunity:Studies show that tannins can boost both red and white blood cell counts in bettas, improving their overall immune response.
-
Natural Food Source:As the leaves break down, they form biofilms that provide a natural food source for beneficial microfauna, shrimp, and snails.
-
Mimics Natural Habitat:Catappa leaves help recreate the natural blackwater conditions found in a betta’s native environment.
-
1. Prepare the Leaves:Boil the Catappa leaves for about 5-10 minutes to soften them, help them sink, and encourage the release of beneficial compounds.
-
2. Add to Tank:Place 1-2 leaves into your aquarium for every 5-20 gallons of water.
-
3. Replace as Needed:Over time, the leaves will break down; once you see holes in the first leaf, it’s time to add a new one to maintain the tannin level.
-
4. Create a Blackwater Environment:For a more natural look and increased benefits, you can add other botanicals such as Malaysian driftwood or cholla wood to further lower the pH and enhance the blackwater effect.
-
Water Staining:The water will turn brown from the tannins, but this is healthy for your fish and not a sign of dirty water.
-
Bioactive Cycle:The breakdown of the leaves supports a healthy biofilm and beneficial bacteria, which can contribute to a stable aquarium cycle.
-
Powder Form:You can also use Indian almond leaf powder, adding a small amount of the powder to a small amount of water to make a “tea,” and then adding a small portion to your tank.
