| Husbandry Information | |
| Feeding | Eats worms, crustaceans, insects and small fish. Frozen and pellet foods are accepted in captivity. User data. |
| Furniture | Provide outcrops of stones that the fish can swim in and around. Ceramic or PVC pipes, if supplied will be used as a cave. The substrate can be sand or fine gravel. Plants and wood decorations are a welcome addition and the fish will lounge on them on occasion but be sure to leave open water for swimming. |
| Compatibility | Peaceful with members of its own species |
| Suggested Tankmates | Tankmates should be large enough not to be eaten. Fishes from the same region safe to house with it include Hemibarbus labeo, large Carassius auratus, and the Coreoperca spp. |
| Breeding | A breeding report in the Korean language book Korean Freshwater Fish (Pet Care vol. 4) states that courtship activity occurs over a 3 to 7 day period. During that time, the pair selects a spawning site among large gravel and stones. The males will frequently nudge the females belly and ventral regions and appears to assist in pressing the eggs out. Eggs are attached to the side or tops of stones and guarded by the male until hatching, The small fry feed first in infusoria but grow rapidly and can soon take newly hatched brine shrimp and finely powdered foods. In nature, spawning occurs in May/June and by September the fry have generally reached about 5cm in length. |
