Hi Fin Chinese loach

Elegant, exotic, and wonderfully unique — the Hi Fin Chinese Loach (Leptobotia elongata or similar hillstream species) is a striking and rarely seen loach prized for its dramatically elongated, sail-like dorsal fin and beautifully patterned body. A true collector's fish that brings a touch of the exotic to any well-maintained aquarium.

Overview

Appearance

The Hi Fin Chinese Loach is distinguished by its spectacular elongated dorsal fin that rises dramatically above the body like a sail, giving it a regal, eye-catching silhouette. The body is typically patterned with bands or mottling in shades of brown, black, and cream, providing excellent camouflage in a natural riverbed setting. Their streamlined body and active nature make them a dynamic presence in any aquarium.

Water Parameters & Tank Setup

• Temperature: 65 – 75°F (18 – 24°C) — a cool-water species
• pH: 6.5 – 7.5
• General Hardness (GH): 4 – 15 dGH
• Tank Size: Minimum 40 gallons
• Flow: Moderate to strong — they come from well-oxygenated rivers
• Substrate: Smooth river gravel or sand with flat rocks and driftwood
• Decor: Caves, smooth rocks, and hiding spots; open swimming areas in the mid and lower water column

Diet & Feeding

• Staple: Sinking pellets, wafers, and loach-specific foods
• Treats: Frozen bloodworms, brine shrimp, daphnia, and blanched vegetables
• Natural grazing: Algae and biofilm on rocks and driftwood

Feed in the evening as they are most active at dusk and night.

Compatibility & Tank Mates

Peaceful and well-suited to cool-water community tanks. Good tank mates include:

• Other cool-water fish (White Cloud Mountain Minnows, Danios, Hillstream Loaches)
• Peaceful barbs
• Corydoras catfish

Avoid tropical fish requiring warm temperatures, and aggressive species that may damage their distinctive dorsal fin.

The Hi Fin Chinese Loach is a rare and captivating fish — its dramatic dorsal fin and active personality make it a standout addition to any cool-water aquarium. A true collector's species for the discerning aquarist.
