The red junglefowl was the primary species to give rise to today's many breeds of domesticated chicken (G. g. domesticus); additionally, the related grey junglefowl (G. sonneratii), Sri Lankan junglefowl (G. lafayettii) and the Javanese green junglefowl (G. varius) have also contributed genetic material to the gene pool of the modern chicken.
Usually, the female lays about 400 eggs on a stone and the male immediately fertilizes them. [5] At a temperature of 25.5 °C, after 48 hours they hatch. [ 5 ] After five and a half days, the fry swims freely and are led mainly by the female, while the male is mainly engaged in the defense of the territory.
The breeding aquarium for the rummy-nose tetra, in addition, needs to be sterilised prior to use, as the fish produces eggs that are notoriously sensitive to bacterial and fungal infection. Use of an antifungal agent is strongly advised once spawning is completed in order to prevent various fungi from attacking the eggs.
Junglefowl are the only four living species of bird from the genus Gallus in the bird order Galliformes, and occur in parts of South and Southeast Asia.One of the species in this genus, the red junglefowl, is of historical importance as the direct ancestor of the domestic chicken, although the grey junglefowl, Sri Lankan junglefowl and green junglefowl are likely to have also been involved.

Some fish have evolved to exploit the mouthbrooding behaviour of other species. Synodontis multipunctatus, also known as the cuckoo catfish, combines mouthbrooding with the behavior of a brood parasite: it eats the host mouthbrooder's eggs, while spawning and simultaneously laying and fertilizing its own eggs. The mouthbrooder (typically a ...
Their innate aggression makes them good candidates for keeping in a monospecies aquarium, however this depends on a number of factors similar to all tropical cichlid fish; swimming and territory space, other aquatic inhabitants, diet and feeding frequency and tank layout. Jewel cichlids are omnivorous and will eat both live foods and fish flakes.
The nests are constructed as a place for fertilized eggs to be deposited while incubating and guarded by one or both parents (usually solely the male) until the fry hatch. Bubble nests can also be found in the habitats of domesticated male betta fish. Nests found in these types of habitats indicate a healthy and happy fish. [2]
