Used by Bagan Plakat fighter breeders/keepers for hardening their fish's scales.

The bark of the Teak tree (Tectona grandis) has long been used in the same way as Indian Almond bark (Terminalia Catappa), remedies include:

bite injuries
fungal diseases
hardening of scales
fin rot
color enhancement
burns off fat.

​

Teak Bark contains tannins that get released into the water after adding the bark. These substances are disease-resistant and slightly lower the ph. It takes a long time for teak bark to decay in the water. Shrimps eat the soft bark and so can have food for a long time.

Tectona grandis is native to southeast Asia, mainly Thailand, Indonesia, Malaysia, and Burma and thus the bark is widely used by South Asian Tropical Fish breeders and keepers. The coloration of fish is greatly improved, and it has very positive effects on strengthen the fishes' scales. It maintains the water PH level and serve as a natural antibiotic. It also dry's up the fat on most fish, resulting in more muscle, making your fish more athletic and agile.

​

Unlike the Indian Almond Leaves and Indian Almond Bark, Teak Bark does not color your aquarium water the same way, the color is much lighter so it's ideal for Aquarists who want the benefits of Indian Almond Bark without the tea stain color.

​

Aquarists also use Teak Bark to mimic the natural conditions of their fish in their aquaria. Simply adding Teak Bark to your aquarium will release compounds by the bark which alter the chemistry of the water, making the aquarium more similar to the habitat from which the fish hails. The Teak Bark is also ideal as leaf litter in vivarium's.
