The leaves added a natural look to my betta’s tank. The water turned a soft brown, which I love. My betta has started building bubble nests near the leaves, which is a great sign of healthy behavior.

Works well in a 5-gallon nano tank. The dark water effect is subtle but noticeable. Leaves don’t fall apart easily and stay intact for weeks.

I’ve used these for two months now and they still look fresh. The fish seem more active and the tank feels more natural. Great for creating a peaceful environment.
