Kuhli Loach

Eel-like night shift workers that wriggle through sand and hide by day. Soft substrate, tight lids, and groups of five or more bring out their playful side.

• Minimum footprint: 20 gallons; a 30+ gallon tank gives real swimming room.
• Preferred swimming zone: bottom of the water column.
• Social — keep a group of at least 5.
• Care level: moderate.

• Temperature: 75–86°F
• pH: 5.5–7
• Hardness: 1–8 dGH (Soft)

Stable parameters matter more than perfect ones — aim for consistency before chasing an exact number.

Standard tanks at or above the recommended 30 gallons:

• 30 gallon 36 × 12 × 16″
• 40 gallon Breeder 36 × 18 × 16″
• 40 gallon Long 48 × 12 × 16″
• All tank sizes

• Start from a 20 gallon minimum and plan the full group size (5+) before you buy.
• Activity level is moderate, which affects how much of the tank it uses and how much it adds to the bioload.
• Zoning matters: this species lives mostly in the bottom zone, so choose tank mates that occupy other levels.

Compatibility depends on tank size, water chemistry, temperament, and adult size. Run a full check against any species in our database.
