The tank sizes can vary widely depending on the needs of the particular species, and the temperature is usually in the tropical range of 76-82 °F. The substrate can vary from sand to gravel, but many aquarists choose crushed coral or aragonite sand, both of which help raise the hardness and pH to an acceptable level.
It can also be extremely useful when the fish keeper plan to stock a tank full of territorial aggressive fish, such as African cichlids, where the later added fish can be at a disadvantage. [ 6 ] However, care in adding ammonia for fishless cycling must be used, too high of an ammonium concentration can kill nitrifiers.
In fishkeeping, a refugium is an appendage to a marine, brackish, or freshwater fish tank that shares the same water supply. It is a separate sump , connected to the main show tank. [ 1 ] It is a " refugium " in the sense that it permits organisms to be maintained that would not survive in the main system, whether food animals, anaerobic ...
The oscar (Astronotus ocellatus) is a species of fish from the cichlid family known under a variety of common names, including tiger oscar, velvet cichlid, and marble cichlid. [2] In tropical South America, where the species naturally resides, A. ocellatus specimens are often found for sale as a food fish in the local markets.
Freshwater fish may be either coldwater or tropical species. Although freshwater aquariums can be set up as community tanks, coldwater and tropical fish are generally not mixed due to incompatibilities in temperature requirements. Coldwater aquariums house goldfish and other species that do not require a heating apparatus.
Living Color Aquariums (also known as Fish Tank Kings on National Geographic Wild [1]) is a custom acrylic tank manufacturing company with headquarters in Fort Lauderdale, Florida. [2]) They design and manufacture custom acrylic aquariums , water features , acrylic art, and themed exhibits.
Ideally, the level of ammonia (NH 3) and ammonium compounds (i.e. those containing NH 4 +) in fish tanks should be zero. Although trace amounts are generally harmless, they can still lead to problems over time. [1] Understanding the nitrogen cycle is essential for the keeping of any aquatic life. The source of ammonia in fish tanks is fish's ...
The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]
