The Ceylon Combtail is a freshwater fish endemic to Sri Lanka, widely distributed in rivers, streams, marshes, ponds, and forest wetlands across the island. It prefers slow-moving or still waters with dense aquatic vegetation, submerged roots, and shaded habitats where it can find shelter. Like other gouramies, it possesses a specialized labyrinth organ that allows it to breathe atmospheric air, enabling it to survive in waters with low oxygen levels. This hardy and territorial species is usually solitary or found in pairs, especially during the breeding season. It feeds on aquatic insects, insect larvae, small crustaceans, worms, algae, and plant material, making it an omnivorous species. During reproduction, males become more aggressive while guarding their breeding territory and offspring. As one of Sri Lanka’s few native gouramies and a species found nowhere else in the world, the Ceylon Combtail is an important part of the island’s unique freshwater biodiversity and is valued by aquarium enthusiasts for its distinctive appearance and resilience.
