Tannin Aquatics Dried Teak Leaves (Package of 6 Leaves)

Origin: Nakhon Sawan, Thailand

The leaves of the Teak Tree, (Tectona grandis), provide numerous benefits for tropical fish. When steeped in water, the leaves release rich organic compounds, such as tannins, humic acids, and flavonoids.  Although they impart a very slight tint other water, it is much less significant than Catappa, or even Guava leaves! 

Teak leaves have been used for decades by many Southeast Asian tropical fish breeders and hobbyists, as they are thought to have beneficial prophylactic properties that protect fish from skin infections. There are claims that it does stuff like help harden the scales of fishes, heal bite injuries, and prevent fin rot. It's also preferred that it enhances the colors of fish (not too outrageous, because it does have beneficial tannins and humic substances), and our personal favorite, "burning off fat" from the fish. We're just not going to touch that one!

Other fishes, such as South American cichlids, Tetras, and catfishes, Bettas, Guaramis, killifish, and Barbs will benefit from their use much as they would from any of the other leaves which we offer. Some ornamental shrimps utilize the decomposing leaves as a supplemental food source, and they're really nice in vivariums! They are much larger than our Catappa, Magnolia, and Guava leaves, so they provide an interesting aesthetic touch, as well!

Tannin Dried Teak Leaves are harvested for us by hand by a family-owned operation from a small village in Nakhon Sawan, Thailand, and are free of pesticides, herbicides, and pollution. They're gathered after having fallen from the trees, rinsed and sun dried, rolled flat for ease of use and packaging.  As with our other natural products, we actually know the people who are handling our leaves personally, and, as fish keepers themselves, they understand exactly what we're using them for, so you're assured consistency, quality, and value every time. 

Our Dried Teak Leaves average around 6" to 8" (15.24- 20.32cm) in length or more, and come in a package of 6. They're pretty, exotic-looking and very, well- "jungle-like!" They have lots of character, and each one is slightly different, wrinkled...a bit rough around the edges..natural. Beautifully imperfect!  These are super cool, very well-handled leaves by people who only do this for a living. That being said, they're a bit dry and delicate, have some holes and tears in them, and are not "perfect" in that sense. However, they bring some very nice, very different aesthetics, and are surprisingly long-lasting leaves when submerged.

Your purchase of these leaves helps support this rural operation by providing good employment for the local families.

Before using the leaves in your aquarium, we recommend steeping them in hot water for about 15 minutes, then soaking them in fresh water overnight to let them become waterlogged. Then, you can place them on the bottom of your aquarium like any other leaves. 

Just how many leaves to use depends upon what type of effect you're looking for. We recommend starting off slowly, with 1 or 2 leaves for each 10 gallons of capacity, at least to start, so you get a "feel" for their impact on your aquarium and its inhabitants. As the leaves decompose, you can leave them in, or siphon out and replace as desired.


All of our aquatic botanicals are intended for ornamental aquarium or terrarium use only. Please use common sense and take the time to boil or soak all botanicals prior to using them, to reduce the possibility of problems. Always go slow when introducing any botanicals into your systems, so you can judge the effect they have on your fishes and plants. They are not intended for human consumption. DO NOT INGEST!



 NOTE: Due to natural variations of leaves, each one will appear different. The photo is a representation of what to expect.
