The rosy barb is an active, peaceful species well-suited for a community aquarium. It is considered one of the hardiest barbs, undemanding and beautiful, and most impressively colored during the mating period. It can be kept together with other small fish but can be aggressive toward other fish and nip their fins.
The female will spawn 200 to 300 eggs and scatter them on plants and the substrate. It may eat its own eggs and small fry. The eggs hatch in one to two days and the fry are free-swimming after two more days. After five weeks, the hatchlings will be about 1 cm. long and easily identifiable as cherry barbs. [9]
The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods. Knowledge of mode of reproduction is also essential for its artificial manipulation to breed improved types.
Though less common to the hobby than other related barbs, this peaceful, active, egg-laying fish is compatible with other related species in the home aquarium such as tiger barbs (Puntigrus tetrazona), and rosy barbs (Pethia conchonius) and other fast swimming cyprinid species of similar size.
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
The swamp barb is an open water, substrate egg-scatterer, and adults do not guard the eggs. During breeding time, the males display very prominent red bands, which lasts for around two days (rivaling Rosy Barbs - P. conchonius), while females display red stripes which last around 5 hours.
Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however.
The Odessa barb is a voracious eater that will take most foods given, including flakes and frozen foods, such as Bloodworms. The Odessa barb can be kept with other peaceful fish species including various Tetras, various Corydoras catfish, danios, and the Ram cichlid. A selectively bred strain has been created in North America by Select Aquatics ...
