Catappa Bark from Aquatic Arts
The Catappa Tree (Terminalia catappa) is a large tropical tree in the leadwood family. Its bark offers numerous benefits to aquatic life and plants in the aquarium.
This natural bark provides antibacterial properties that support fish and invertebrates, especially during the initial acclimation phase. It can serve as a supplemental food source and releases tannins and humic acids into the water, which help promote slime coat development and reduce the risk of infections.
The bark increases surface area in the tank, which supports beneficial microbial activity and enhances water stability.

FAQ
What are the main benefits of using Catappa Bark in an aquarium?
Catappa Bark provides antibacterial properties that help protect fish and invertebrates, especially during the first days after introduction. It releases tannins and humic acids, which support slime coat formation and reduce infection risks. It also increases surface area for beneficial microbial growth.
Is Catappa Bark safe for all types of aquatic animals?
Catappa Bark is generally safe for most fish and invertebrates. However, some sensitive species may react to tannins or humic acids. It is recommended to monitor water parameters and animal behavior when first introducing the bark.
How should Catappa Bark be added to the aquarium?
Add the bark gradually to the aquarium substrate or decor. Avoid large quantities at once to prevent sudden changes in water chemistry. Monitor water parameters closely after introduction.

I added Catappa Bark to my community tank and noticed my fish seemed more active and healthier. The water color changed slightly, which I liked. My bettas have been thriving, and I’ve seen better slime coats. It’s a simple addition with real benefits.

The bark fits well in my planted tank. It’s natural and doesn’t cause any issues with water chemistry. I’ve used it for a few weeks now and my shrimp are more active. A little tannin effect is expected, but it’s not overwhelming.

Great product! My aquarium has a more stable environment since I started using the Catappa Bark. The fish seem less stressed, and the water clarity has improved over time. I recommend it for both fish and plant health.
