What Celebes Ricefish look like
The Celebes Ricefish, or Oryzias celebensis, exhibits a slender, laterally compressed body that typically reaches a maximum adult size of approximately 1.5 inches (4 cm). This species displays sexual dimorphism, with males possessing elongated dorsal and anal fins that are more pronounced than those of females, contributing to a sail-like appearance. The body is translucent, allowing for a glimpse of the internal structures, and is adorned with iridescent blue eyes that enhance its visual appeal. Notably, the dorsal fin is elongated and sail-like, which is a distinctive feature of this species. The Celebes Ricefish lacks significant defensive adaptations, relying instead on its small size and agile swimming to evade predators. The presence of a lateral line system aids in detecting water movements, which is crucial for a surface-dwelling species.
Behavior & temperament
Oryzias celebensis is primarily a surface-dwelling fish that exhibits a peaceful temperament and is often found in small groups, although it does not exhibit strict schooling behavior. This species is typically found in shallow, slow-moving waters of its native Sulawesi, where it occupies the upper layers of the water column. The Celebes Ricefish is known for its breeding behavior as an egg scatterer, where females release eggs over vegetation or substrate, allowing for external fertilization. The species displays a non-aggressive demeanor, making it suitable for community tanks with similarly sized tank mates.
Diet & feeding
In the wild, the Celebes Ricefish is an omnivore, feeding on a varied diet that includes small invertebrates, algae, and detritus. In captivity, it thrives on a balanced diet of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia to ensure optimal health and coloration.
