Indian almond leaf

Vernacular name for leaves of the leadwood tropical tree species Terminalia catappa which are commonly sold dried for use in aquaria because the organic compounds contained within them are considered beneficial for certain fish species. In particular they may aid in simulation of blackwater conditions and inhibit the growth of some undesirable microorganisms, as well as proving an effective addition to a natural-looking display. Also known as Ketapang leaf, presumably in reference to the city of that name in West Kalimantan province, Indonesian Borneo.
