Guppies prefer a hard-water aquarium with a temperature between 25.5 and 27.8 °C (78 and 82 °F) and salt levels equivalent to one tablespoon per 19 L (5 US gal). [60] They can withstand levels of salinity up to 150% that of normal seawater , [ 61 ] which has led to them being occasionally included in marine tropical community tanks, as well ...
Poecilia picta, the swamp guppy, is a species of livebearer fish found in South America. It is closely related to the common guppy , P. reticulata , and shares its geographic range but tends to be found in more brackish environments.
Poecilia wingei is a very colorful guppy species, similar to the fancy guppy often found in pet shops. The species was first collected from Laguna de Patos in Venezuela by Franklyn F. Bond in 1937, and rediscovered by Dr. John Endler in 1975.
One of the few common brackish water plants in the trade, the Java Fern (Microsorum pteropus) appears to be toxic to these fish and should not be planted with "scats". Hogchoker: Trinectes maculatus: 3" Often sold under the misnomers "Freshwater Flounder" or "Freshwater Fluke", but is in fact a brackish water if not marine fish
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...
The guppies temperature and water quality is taken in a book "aquarium for Dummies", it would be good to have science papers about that, since every book and internet site, even the most popular and trusted, all gives different temperatures, etc... "Dropping a number of two to 200 fry at a time" The site that is mentioned is not a research paper.
The ocean temperature plays a crucial role in the global climate system, ocean currents and for marine habitats. It varies depending on depth, geographical location and season. Not only does the temperature differ in seawater, so does the salinity. Warm surface water is generally saltier than the cooler deep or polar waters. [1]
They are found most abundantly in shallow water protected from larger fish. [11] Mosquitofish can survive relatively inhospitable environments, and are resilient to low oxygen concentrations, high salt concentrations (up to twice that of sea water), and temperatures up to 42 °C (108 °F) for short periods.
