Aquarium Botanicals: Guava Leaves

The leaves of the Guava tree (Psidium guajava) provide many benefits for aquaria, including their well-documented antibacterial properties and their great value as a supplemental food source for ornamental shrimp. Our Guava leaves are harvested after they have naturally fallen, an important point with Guava leaves, and will be depleted of chlorophyll, sugars, and sap.

Guava leaves dissolve much more slowly than other leaves and will last longer before requiring replacement! They will leach some tannins into the water, but the coloration will not be nearly as pronounced as that created by almond leaves, for example. If you prefer a lighter tannin color, try our guava leaves. They can be boiled for a few minutes to help them sink faster. Shrimp will enjoy feeding on the leaves after being boiled for several minutes.

Guava leaves are a great food source for shrimp and fish, and many species also like to eat the biofilm that the leaves create. These leaves also contain polyphenols, carotenoids, flavonoids and tannins. Carotenoids have been suggested in scientific studies to promote spawning health of the parent and the offspring.
