The male's dorsal fin is pointed, while the female's is rounded or curved. [3] They carry touch-sensitive cells on their thread-like pelvic fins. [4] Dwarf gouramis sold in fish stores may also be solid colors (e.g., powder blue dwarf gourami or red flame variety) which are nothing but captive bred color morphs of the same species.
The three spot gourami (Trichopodus trichopterus), also known as the opaline gourami, blue gourami, and gold gourami, is a species of fish native to southeastern Asia, but also introduced elsewhere. [1] This gourami gets its name from the two spots along each side of its body in line with the eye, considered the third spot. [3]
Compatibility depends on the species of gourami and the fish it is housed with. Some species (e.g., Macropodus or Belontia ) are highly aggressive or predatory and may harass or kill smaller or less aggressive fish; whereas, others ( Parosphromenus and Sphaerichthys , for instance) are very shy or have specific water requirements and thus will ...
Although an attempt to introduce a population in southern France failed, the giant gourami became well established in other French colonies. [4] In the late 1880s, attempts to introduce the giant gourami to California waters as food fish were unsuccessful. In the 1950s, a giant gourami population was established in Hawaii. [8]
Unlike most other species, wherein the female takes on the dominant parenting role, here the male Honey Gourami assumes the guardian role at an early stage. The male continues guarding the nest, and rebuilds and repairs it if needed, while the female leaves the area. [ 7 ]
The thick-lipped gourami has been widely transported around the world for the aquarium fish industry. [2] It is a generally peaceful fish for a tropical community aquarium . [ 4 ] Like other Trichogaster species, it tends to be a bit shy and hides under plant life when it feels threatened. [ 5 ]
The male can be left with the eggs until they hatch. The eggs hatch in 1–2 days and remain in the nest for a further 2–3 days absorbing their yolk sac. The free-swimming fry are tiny and require microscopic infusoria until they are large enough to accept newly hatched brine shrimp or dry food.
Male and female broods are distinguished by examining the gonads and based on the external morphological features: the upper lip of the male is more pronounced and the dorsal ventral fins are more pointed at the posterior end than those of the female. Like other Anabantoids, this species is a bubble nest builder and the fertilization is external.
