Badam Pods (from the Terminalia catappa tree, commonly known as the Indian Almond tree) are a natural botanical used in aquariums for their aesthetic appeal and beneficial water-conditioning properties. These pods are the dried fruit shells of the same tree that produces Indian Almond Leaves (Catappa Leaves), which are widely known for their health benefits in aquariums.

Badam Pods feature a tough, ridged outer shell with a deep brown coloration that darkens underwater, adding a natural and rustic look to any aquascape. When submerged, they slowly release tannins — natural compounds that tint the water a light tea color, lower the pH slightly, and create conditions similar to tropical blackwater environments. These tannins also have mild antibacterial and antifungal properties, promoting the overall health of fish and shrimp.

Ideal for tanks housing Betta fish, shrimp, Tetras, Apistogrammas, and other soft-water species, Badam Pods also encourage the growth of biofilm, which provides a natural food source for shrimp and fry.

Before adding to the aquarium, it’s best to boil the pods for 10–15 minutes to remove excess tannins and ensure they sink. Once introduced, each pod can last several months, gradually breaking down and enriching the ecosystem.

In addition to their functional benefits, Badam Pods offer aesthetic and behavioral enrichment — serving as natural shelters, spawning sites, or simply decorative accents that mimic riverbed and forest-stream habitats.

Size Guide: They're about (10cm) or so in diameter on average, with openings around (4.45-6.35cm). These pods will leach some tannins into the water over the long term.
