Acantopsis dialuzona – Horseface Loach (6–8 inches)

Overview

The Horseface Loach (Acantopsis dialuzona) is a distinctive bottom-dwelling freshwater fish named for its long, horse-like snout. Its sandy-brown, mottled body provides camouflage against substrates, making it a fascinating and unusual aquarium inhabitant. A peaceful burrower, it spends much of its time sifting through sand in search of food and prefers a quiet environment with hiding places.

Size

Adult length: ~6–8 inches (15–20 cm).

Bottom-dwelling, burrowing species.

Behavior & Social Needs

• Peaceful and shy, best kept in groups of 3–6 or more to reduce stress.

• Spends much time buried in soft sand with only its head visible.

• Good tankmates include peaceful community fish such as rasboras, barbs, loaches, and gouramis. Avoid aggressive or very large species.

Tank Conditions

• Tank size: 40 gallons minimum for a small group (larger preferred).

• Temperature: 75–82°F (24–28°C).

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

• Setup suggestions: Fine sand substrate (essential for burrowing), driftwood, rocks, and plants for cover. Provide dim lighting and gentle to moderate water flow.

Diet

Omnivorous: Feeds by sifting sand for small organisms. In aquariums, accepts sinking pellets, algae wafers, bloodworms, tubifex, brine shrimp, and finely chopped foods.

A varied diet ensures good health and activity.

Lifespan & Hardiness
