Ichthyological terms, not general ones.
In ichthyological and aquarium literature typically refers to water rich in humic acids and poor in nutrients such as that associated with ancient peat swamps or parts of the Amazon river drainage, and thus differs from clearwater and whitewater. Fish species inhabiting such environments typically require similar conditions in captivity, especially if wild caught.

Method of acclimation used for sensitive fish species in which the animals are first placed into a clean bucket or other container before water is slowly dripped in by siphon from the aquarium into which they are to be introduced. Can be carried out using a purchased kit or home-made using a length of airline plus an airline clamp.
Abnormal bulging of the eye from the orbit commonly referred to as 'pop eye' in aquarium literature and resulting from excessive accumulation of fluid or gases at the back of the socket. Not a disease but a secondary sympom of some other infection or physical issue.

Term used in the fields of genetics and selective breeding in reference to the first filial generation, i.e., hybrid offpsring, of a cross between two distinctly different parental lines. Often used in aquarium literature to refer to offspring of F0 parents whether of the same species or not.

Small, motor-driven, type of external filter that literally hangs over the edge of the aquarium. Unsuitable for larger aquaria and often abbreviated to HOB or HOT (hang on tank).
Length of flexible cable buried under the substrate in an aquarium and used to maintain constant water temperature. Also popular in planted aquaria due to the associated circulation of water within the substrate which aids in nutrient exchange between plant roots and the surrounding environment.
A filter located inside the aquarium and typically used for smaller tanks due to its reduced capcity for media compared to external filters.
Abbreviation of 'local fish shop' or 'local fish store' commonly used in the aquarium h0bby.
Type of substrate mostly used in marine aquaria collected directly from natural marine habiats and packaged in such a way as to maintain the resident microorganisms. Significantly reduces the time required to mature a new aquarium.
