Clown Loach

The Clown Loach (Chromobotia macracanthus) brings bright orange color, bold dark bands and lively group behavior to a large freshwater aquarium. Native to Sumatra and Borneo, it is a social bottom-dwelling fish that spends time exploring shelters and searching the substrate for food. Adults commonly reach 20–30 cm (8–12 inches), with larger individuals approaching 40 cm (16 inches). Its small purchase size should never determine its permanent home.

Aquarium and care

Keep at least six together and plan for their adult group. We recommend an aquarium of approximately 180 US gallons (680 L) or larger, with a footprint at least 180 × 60 cm (6 × 2 feet); especially large fish or additional tankmates need more space. Use an established, fully cycled aquarium with strong filtration, good oxygenation and regular partial water changes. Maintain approximately 25–28°C (77–82°F), pH 6.5–7.0 and soft to moderately soft water.

Provide fine sand, shaded areas and smooth, roomy shelters among securely placed wood or rocks. Leave open swimming routes and make sure retreats cannot trap a growing fish. Consistent water quality and a calm introduction help this sensitive species settle.

Feeding

Offer a varied omnivorous diet built around quality sinking loach pellets or wafers. Add suitable frozen invertebrates and small portions of vegetable foods. Ensure every fish receives food; leftovers from other fish are not a complete diet. Clown Loaches may eat snails, but still need a large permanent aquarium and a balanced diet.

Temperament and tankmates

Choose robust, peaceful companions that suit the same warm water. Avoid aggressive fish, tiny ornamental shrimp and fish easily disturbed by an active loach group. Provide several feeding and resting areas so subordinate loaches can withdraw. Their social behavior is best enjoyed with other Clown Loaches, supported by adequate space throughout their long lives.
