Guava leaves are a great food source for shrimp and fish in the aquarium and many species love eating the biofilm the leaves create. These leaves contain polyphenols, carotenoids, flavonoids, fiber and potassium. Carotenoids have been suggested in scientific studies to aid spawning health of both the parent and the offspring.
Guava leaves produce less tannins than catappa leaves and last longer in the aquarium before breaking down. If you prefer a lighter tannin color try Guava leaves. They can be boiled for a few minutes to help them sink right away if you prefer. Shrimp will enjoy feeding on the leaves after being boiled for several minutes.
We recommend boiling ALL leaves and botanicals for a couple minutes in tank safe water before use in the aquarium.
