inbreeding depression

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.

infusoria

Collective term for certain members of the protozoan Phylum Ciliophora, of which it is considered a subclass in certain classification systems. Members naturally inhabit infusions of decomposing organic material and some are cultured by aquarists in order to feed very small fish fry. The name was formerly applied to a much larger group of aquatic microorganisms which also included some other protist groups and unicellular algae.
