The tank water should be around 78 to 82 degrees Fahrenheit, according to Aquatic Veterinary Services. If the temperature is out of this range, your betta fish is at risk for several health issues.
Female Odessa barb. The Odessa barb is a small fish with a laterally compressed body. Among 28 adult specimens (12 males, 16 females) measured in its species description, both sexes were up to about 4.6 centimetres (1.8 in) SL. [4]
The tropical climate of the betta's natural habitat is characterized by sudden and extreme fluctuations in water availability, chemistry, and temperature. [22] Water pH can range from slightly acidic (pH 6.9) to highly alkaline (pH 8.2), while air temperatures drop as low as 15 °C (59 °F) and rise as high as 40 °C (100 °F). [ 22 ]
Betta / ˈ b ɛ t ə / is a large genus of small, active, often colorful, freshwater ray-finned fishes, in the gourami family (Osphronemidae). [1] The best known Betta species is B. splendens, commonly known as the Siamese fighting fish and often kept as an aquarium pet.
Betta unimaculata, the Howong betta, is a species of labyrinth fish endemic to the island of Borneo where it is only known from the eastern portion of the island. This species grows to a length of 12.6 centimetres (5.0 in) TL , one of the largest known species of Betta .
The use of shallow water is also because fertilized eggs need to be aerated in order to hatch successfully. [3] Various stimuli have been shown to affect onset the construction of bubble nests, such as rapid changes in temperature, barometric changes, fluctuations in rainfall, various fish tank materials, and presence of other males or females.
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 swim bladder is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth without having to waste energy in swimming. [1] A fish with swim bladder disorder can float nose down tail up, or can float to the top or sink to the bottom of the aquarium. [2]
