Clown Rasbora Care Guide
Rasbora kalochroma · Freshwater Fish
What Clown Rasbora look like
The Clown Rasbora (Rasbora kalochroma) exhibits a strikingly vibrant morphology characterized by a deep reddish-orange body that can reach a maximum adult size of approximately 5 cm (2 inches). This species displays sexual dimorphism, with males typically showcasing more intense coloration and slightly elongated fins compared to the more rounded females. A notable feature of the Clown Rasbora is the presence of two prominent, distinct black spots: one located just posterior to the gills and the other at the base of the anal fin, which serve as key identification markers. Additionally, the body is laterally compressed, enhancing its hydrodynamic efficiency, while the presence of an adipose fin contributes to its streamlined profile. The dentition is small and conical, adapted for an omnivorous diet, and the overall fin structure is well-developed, with a forked caudal fin that aids in agile swimming.
Behavior & temperament
Clown Rasboras are typically found in small schools, exhibiting a social hierarchy where individuals display a degree of dominance and submission, particularly during feeding and breeding activities. They predominantly inhabit the mid to upper water column in their native Borneo habitats, favoring densely vegetated areas. Breeding behavior involves egg scattering, where females release eggs among plants, and males fertilize them externally. This species is generally peaceful and exhibits low aggression levels, making them suitable for community tanks; however, they may display territorial behaviors during breeding periods.
Diet & feeding
In the wild, Clown Rasboras are omnivorous, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they thrive on high-quality flake foods, live or frozen foods such as daphnia and brine shrimp, and should be supplemented with vegetable matter to ensure a balanced diet.
Behind the name
The genus name 'Rasbora' is derived from the Malay word 'rasborah', referring to a type of fish, while the species name 'kalochroma' comes from the Greek 'kalos' (beautiful) and 'chroma' (color), reflecting its vibrant coloration.
