Knowra Fishkeeping Fishkeeping Fishkeeping is the care and maintenance of fish in aquariums or ponds. It combines habitat management, water-quality control, feeding, and disease prevention.
Aquarium nitrogen cycle : The microbial conversion of fish waste and uneaten food into less toxic nitrogen compounds in an aquarium. Its bacterial processes make biological filtration possible and prevent toxic ammonia buildup.
Aquarium : A transparent tank or other enclosure designed to hold aquatic organisms and water. The aquarium is the most common managed habitat in fishkeeping.
Aquascaping : The design of planted aquarium landscapes using aquatic plants, hardscape, and deliberate composition. It shapes aquarium layout while requiring plant-compatible lighting, nutrients, and maintenance.
Fish farming : The commercial breeding and rearing of fish for food, stocking, or other products. Fish farming prioritizes production at scale, unlike the usual household focus on care and display.
Aquarium filtration : The removal or transformation of particles, chemicals, and waste by aquarium filter media and equipment. Filtration supports water quality through mechanical, chemical, and biological processes.
Aquatic plants : Plants adapted to grow partly or wholly in water, including submerged and floating species. Plants can provide cover and use nutrients, though they also have specific light and care needs.
Koi pond : An outdoor pond designed to keep koi carp, usually with substantial filtration and water circulation. Koi keeping applies fishkeeping principles to a large outdoor habitat.
Aquaculture : The cultivation of aquatic organisms under managed conditions for food, commerce, conservation, or research. Fishkeeping is a small-scale form of managed aquatic animal care within this broader practice.
Water chemistry : The chemical composition and reactions of water, including its acidity, hardness, and dissolved substances. Fish health depends on suitable pH, hardness, and concentrations of dissolved compounds.
Freshwater aquarium : An aquarium containing freshwater organisms and water with low dissolved salt concentration. Freshwater systems are a common setting for keeping fish at home.
