Vanmanenia pingchowensis – Cherry Mouth Loach (5–7 cm)

Size

• Adult length: ~5–7 cm (2–2.8 inches).

• Flattened, elongated body adapted for clinging to rocks and navigating strong currents.

Behavior & Social Needs

• Generally peaceful and shy, particularly around larger or aggressive fish.

• Best kept in small groups of 3–5 to encourage natural behavior while maintaining personal territories around hiding spots.

• Compatible tankmates include small, non-aggressive species such as rasboras, small tetras, dwarf shrimp, and other hillstream species. Avoid aggressive or boisterous fish.

Tank Conditions

• Minimum tank size: 20–30 gallons for a small group.

• Temperature: 72–78°F (22–26°C).

• pH: 6.5–7.5, slightly acidic to neutral preferred.

• Setup suggestions: Fast-flowing, well-oxygenated aquarium with smooth rocks, driftwood, and plenty of hiding spots. Fine gravel or sand substrate is ideal. Moderate to strong water current replicates natural habitat.

Diet

• Omnivorous but primarily grazers.

• Feed on algae, biofilm, and specialized sinking wafers or pellets for hillstream loaches.

• Supplement occasionally with blanched vegetables (zucchini, spinach) or small live/frozen foods like daphnia.

• Continuous grazing opportunities are important for health and coloration.

Lifespan & Hardiness

• Hardy if provided with clean, oxygen-rich water and strong current.

• Sensitive to poor water quality; stable conditions are essential.

• Average lifespan: 4–6 years in captivity.
