What Phoenix Rasbora look like
Boraras merah, commonly known as the Phoenix Rasbora, is a diminutive, laterally compressed fish that typically reaches a maximum adult size of approximately 1 inch (2.5 cm). This species exhibits sexual dimorphism, with males generally displaying more vibrant coloration, particularly in their red and pink hues, compared to the more subdued tones of females. The fish features a distinctive broken black lateral line, characterized by an oval spot located mid-body accompanied by dashes, rather than a continuous stripe. Its body is adorned with a delicate, translucent dorsal fin and a small adipose fin, which contribute to its streamlined appearance. Additionally, the presence of well-developed, sharp dentition allows it to effectively capture small prey, while its small size and coloration serve as defensive adaptations against predation in its natural habitat.
Behavior & temperament
The Phoenix Rasbora is a social fish that thrives in small groups, often exhibiting a schooling behavior that enhances its safety from predators. It primarily inhabits the mid to upper water column in its native Bornean streams and swamps, where it engages in active foraging. Breeding occurs in a manner typical of egg scatterers, with females releasing eggs among aquatic vegetation, while males engage in courtship displays. This species is generally peaceful and exhibits low aggression levels, making it an ideal candidate for community tanks, though it can display territorial behavior during breeding periods.
Diet & feeding
In the wild, Boraras merah primarily feeds on small invertebrates and zooplankton, making it a micropredator. In captivity, it requires a varied diet that includes high-quality flake food, micro-pellets, and live or frozen foods such as daphnia and brine shrimp to ensure optimal health and coloration.
Behind the name
The genus name 'Boraras' is derived from the local name for the fish in Borneo, while 'merah' translates to 'red' in Malay, referring to the fish's vibrant coloration.
