Male and female individuals of Betta imbellis can live together outside of breeding season, as well as getting together for breeding. Males will build a bubble nest before breeding. After mating, the male catches the falling eggs and places them in his bubble nest. In 1–2 days, the eggs hatch and continue to absorb their yolk sack for 2 days.
Male individuals of Betta smaragdina will build a bubble nest before breeding. The temperature at which breeding typically occurs is 25.6 to 26.7 °C (78.1 to 80.1 °F). Males and females can live together and the male and female should already live together for breedi
Betta albimarginata is a species of betta fish, endemic to the island of Borneo where it is only found in the Indonesian province of Kalimantan Timur. It inhabits the shallows (5 to 10 cm (2.0 to 3.9 in)) of forest streams amongst vegetation and debris along the shores. This species grows to a length of 2.8 cm (1.1 in). [3] It is a ...
The King betta generally grows to about 5–6 cm (2–2 1/2 in). Its pigments are generally vibrant beige to a white. As with most bettas, King betta females are smaller and less colorful than the males. The life span of the King betta is short, generally 2–3 years, rarely reaching four.
These are seasonal structures, releasing their contents during the breeding season, and then being reabsorbed by the body. Before the next breeding season, new sperm ampullae begin to form and ripen. The ampullae are otherwise essentially identical to the seminiferous tubules in higher vertebrates, including the same range of cell types. [2]
Close-up of fish melanophores. Fish coloration is produced through specialized cells called chromatophores. The dermal chromatophore is a basic color unit in amphibians, reptiles, and fish which has three cell layers: "the xanthophore (contains carotenoid and pteridine pigments), the iridophore (reflects color structurally), and the melanophore (contains melanin)".
