Keeping Kuhli Loaches: The Peaceful Bottom Scavenger
A guide to keeping kuhli loaches - small, peaceful, eel-like striped loaches that scavenge the substrate, hide by day and come alive in groups, a charming community cleanup fish.
Kuhli loaches are the aquarium's shy, snake-like scavengers - small, banded, eel-shaped loaches that wriggle through the substrate hoovering up leftover food. Peaceful and social, they hide by day and grow bold in the company of their own kind, coming out to forage in a wriggling group. Over a soft substrate in a community tank, they are a charming and useful cleanup crew.
Is it right for you?
Kuhli loaches suit a community keeper who wants a peaceful, unusual bottom scavenger and doesn't mind a fish that hides. Kept in a group, they are easy, hardy and endearing.
System & Space
A planted community tank with a soft, fine substrate to burrow in and plenty of hiding spots suits them; they use the bottom and appreciate caves and dense plants.
Water & Temperature
They like warm, soft, slightly acidic water and stable, mature conditions; being scaleless, they are sensitive to poor water and some medications. Keep the tank clean and stable.
Stocking & Feeding
Keep several together and feed sinking foods, pellets and frozen treats that reach the bottom; they scavenge leftovers but need their own food too. A group brings them out of hiding.
Health & Care
Hardy in stable water but sensitive as scaleless fish to poor conditions and copper or harsh medications; a sharp substrate can injure them. Use fine sand and gentle treatments.
Harvest & Enjoying Them
Ornamental - the reward is a peaceful, entertaining group of scavengers that keeps the substrate clean and behaves fascinatingly in numbers.
Getting Started
Add a group of several to a mature, cycled, warm soft-water tank with fine sand and hiding spots, and give them time to settle and emerge.
Common Mistakes
Keeping too few (they hide and stress), sharp gravel (injuring them), and harsh medications on scaleless fish are the usual mistakes.
FAQ
Why do they hide? They are shy - a group over soft substrate brings them out.
Are they eels? No - they are loaches, just eel-shaped, and peaceful community fish.
