杜氏圆唇鱼

Overview

Cyclocheilos enoplos belongs in discussions of very large river fishes, rather than ordinary community aquariums. Ornamental imports are exceptionally scarce. Its elongated build and substantial serrated dorsal spine help distinguish it from smaller relatives formerly placed in the same genus.

Distribution & habitat

The distribution runs from the Mekong region through Thailand and the Malay Peninsula to Borneo, Sumatra, and Java. Dry-season feeding ranges through midwater and near the bed. Entry into seasonally submerged riverbank forest is thought to occur during the rains.

Mekong populations undertake extensive movements. Juvenile and subadult migrations connect the Phnom Penh and Khone Falls region with the downstream delta, while adults above the falls move upstream in a pattern that appears related to spawning.

Aquarium setup

Only outdoor ponds, public displays, or exceptionally large specialist installations can provide appropriate long-term housing. Use substantial mature filtration and a rigorous maintenance schedule. Aquarium recommendations include replacing approximately half to seven-tenths of the water weekly. Decoration has much less significance than reliable water quality.

Diet & feeding

Small fish can be offered bloodworms, small earthworms, and chopped shrimp. Adults should take larger portions or prey-sized items and may accept pellets, but dried pellets should not make up the staple menu. Adjust food dimensions as the fish grows.

Behaviour & compatibility

It is relatively gentle toward fish beyond swallowing size. Smaller companions remain potential prey, so the description of a peaceful temperament does not make size differences irrelevant.

Sexual dimorphism

Mature females are expected to develop a heavier body than males.

Breeding

Some upstream movements by wild adults appear to be reproductive migrations. This evidence does not establish a practical method for aquarium spawning.
