The Kuhli Loach is a slender, eel-like Southeast Asian loach with tiger-banded colouration.
Secretive and nocturnal, it spends the day hidden in sand or among decor, emerging to wriggle across the bottom in search of food.
Its intermediate rating comes from its sensitivity to water quality and its escape-artist tendencies, not from complex needs.
Patient keepers who provide the right substrate and a group are rewarded with a quirky, long-lived fish.
Housing
Provide a tank of at least 75 litres (20 gallons) with a soft sand substrate they can burrow into safely.
Maintain 24-28C (75-82F), pH 5.5-7.0, in a fully cycled, mature setup; these scaleless loaches react badly to ammonia, nitrite, and unstable water.
Dense plants, driftwood, and caves give the security they need to come out more often.
Every gap, filter intake, and lid opening must be sealed, as kuhlis are determined escapees that squeeze through surprisingly small openings.
Diet
Kuhli Loaches are bottom-feeding omnivores that forage in soft substrate.
Feed sinking pellets, wafers, and tablets, plus frozen or live bloodworm, daphnia, and brine shrimp, all delivered to the bottom where they can reach it.
Because they are shy and often feed at night, offer some food after lights-out so faster fish do not take everything.
They sift sand for morsels, so a fine substrate aids natural foraging and keeps these slim fish well fed.
Health
As scaleless fish, Kuhli Loaches are unusually sensitive to medications, salt, and copper, and to poor water quality and ammonia spikes.
They should only go into a fully matured, stable tank, and any treatment must be dosed cautiously, often at reduced strength.
Watch for skin irritation, faded banding, and lethargy as early warning signs.
Quarantine new fish, keep nitrate low, and avoid sharp substrate.
Given clean, stable water they are surprisingly long-lived, often reaching seven years or more.
Temperament
Kuhli Loaches are peaceful and timid, and are social animals that show natural behaviour only in groups of five or six or more.
Kept singly they hide constantly and are rarely seen, which keepers often mistake for the species simply being shy.
They ignore other fish and suit calm communities with small, non-aggressive tankmates such as rasboras, tetras, and corydoras.
Avoid large or predatory fish that might harass or eat these slender, defenceless loaches.
