Elongated body with a bold yellow or orange dorsal stripe running from head to tail, contrasting with a black body. Small eyes and barbels around the mouth for detecting food. Adults reach 3–4 inches. Smooth fins adapted for bottom-dwelling and burrowing.
8–12 years with proper care
Omnivorous; feeds on live or frozen foods such as bloodworms, brine shrimp, daphnia, and tubifex worms. Also accepts high-quality sinking pellets and blanched vegetables like cucumber or zucchini.
Skunk Loaches are excellent for peaceful community aquariums. Their unique pattern, social nature, and active bottom-dwelling behavior make them both decorative and entertaining. Keeping them in groups encourages natural behavior and reduces stress.
Moderate – requires social groups, hiding spaces, and stable water parameters.

Botia macracantha
Botiidae
Southeast Asia – rivers and streams with rocky and sandy substrates.
Highly social; best kept in groups of 3–6 or more. Peaceful with other community fish.
Feed 1–2 times daily. Offer live or frozen foods like bloodworms, brine shrimp, or daphnia. Supplement with sinking pellets and occasional blanched vegetables. Ensure food reaches the bottom for natural foraging.
Breeding in captivity is extremely rare. Eggs are scattered over fine-leaved plants or substrate with no parental care. Conditioning with protein-rich foods may improve spawning chances slightly.
pH: 6.0–7.5, Temperature: 75–82°F (24–28°C), Hardness: 5–12 dGH, Ammonia/Nitrite: 0 ppm, Nitrate: <20 ppm
Sensitive to poor water quality; prone to ich and bacterial infections if stressed. Provide stable water parameters and sufficient hiding spaces.
Peaceful, social, and moderately active. Best kept in groups of 3–6 or more to display natural schooling behavior. Active during the day and evening, foraging along the bottom and exploring the tank.
Native to Southeast Asia, the Skunk Loach inhabits rivers and streams with rocky or sandy substrates. Adults reach 3–4 inches, making them suitable for medium-sized community aquariums. They thrive in tanks with caves, smooth rocks, driftwood, and hiding spaces. Providing a varied diet ensures health, vivid coloration, and active behavior. Skunk Loaches are excellent for adding movement and interest to the bottom of the tank.
