Serpent Loach Serpenticobitis Octozona 4cm

The Serpent Loach is a small, elongated freshwater loach with striking banded patterns resembling a tiny snake. Secretive and mostly nocturnal, it adds intrigue and natural activity to the substrate layer of community aquariums.

Native to Southeast Asia, including Thailand, Laos, and Cambodia. Found in slow-moving streams, rivers, and floodplain areas with sandy or muddy substrates and dense vegetation.

Omnivorous bottom-feeder. Accepts sinking pellets, frozen foods (bloodworms, daphnia, brine shrimp), and small live foods. Feeding along the substrate encourages natural foraging behavior.

Peaceful and compatible with small to medium-sized community fish such as tetras, rasboras, danios, and dwarf cichlids. Avoid aggressive or large predatory fish that may harass or eat them.

Very low. Prefers to hide during the day and forage at night. Territorial disputes are minimal if multiple hiding spots are available.

Intermediate. Requires soft substrate, stable water conditions, and a well-structured aquarium with hiding places.

• Temperature: 73°F – 79°F (23°C – 26°C)
• pH: 6.0 – 7.5
• Hardness: 2 – 12 dGH
• Notes: Provide sand or fine gravel substrate, driftwood, and plants for hiding; they enjoy shaded areas and gentle water flow.

Secretive, fascinating, and visually striking, the Serpent Loach (Serpenticobitis octozona) is ideal for aquarists seeking a peaceful, bottom-dwelling species for planted or biotope freshwater tanks.
