General Description
Badis corycaeus is a species within the Badidae family of fish, belonging to the order Perciformes. It showcases a deep and dark body compared to its congeners, particularly the species Badis pyema. The fish was poorly documented until the revision paper of 2002, where numerous new species were identified and placed into different groups within the genus.
Aquarium Setup
For optimum care, a 60-litre tank or larger is recommended for B. corycaeus, set up with a sandy or gravel substrate, water-worn rocks, and ample hiding spots like caves. The addition of plants such as Microsorum, Taxiphyllum, or Anubias is optional. The tank should have gentle filtration and lighting, with cave-like structures provided as potential spawning sites.
Behaviour
These fish do not exhibit gregarious behavior and can be aggressive towards each other, especially males. It is advised to maintain them singly or in pairs, allowing sufficient space for territory establishment. Careful selection of tankmates is necessary, as B. corycaeus is slow-moving and may struggle to compete for food with more active fish. Ideal tankmates include peaceful cyprinids and gouramis.
Feeding and Diet
Badis corycaeus are micropredators, feeding on small aquatic crustaceans, insects, and zooplankton. They can be picky eaters and may not readily accept dried foods, so regular offerings of small live or frozen foods like Artemia, Daphnia, or bloodworm are recommended to maintain their health and vibrancy.
Reproduction & Dimorphism
These fish are cave spawners, forming temporary pair bonds during breeding. Male B. corycaeus become increasingly combative when in breeding condition, displaying courtship behavior by intensifying their coloration. After spawning, the male guards the eggs and fry, fanning them with his fins. Females are smaller, with duller patterning compared to the males, who develop extended finnage as they mature.
Habitat and Distribution
Natively, *B. corycaeus is found solely in the upper Ayeyarwady River basin in northern Myanmar, in small streams and tributaries near Myitkyina city and Lake Indawgyi. The fish inhabits shallow, clear waters with moderate currents, alongside other species like Dario hysginon. The area around Lake Indawgyi boasts rich clay substrate with abundant aquatic vegetation, forming a critical ecosystem for these fish.
