Overview
The peppered kuhli loach is a peaceful kuhli for the sandy floor of a quiet blackwater tank. It is not a first fish, but it is not hard to keep.
Did you know
The peppered kuhli loach's species name, piperata, comes straight from the Latin word for pepper. The fish looks as if someone ground a peppermill over a plain tan kuhli.
Caring for the peppered kuhli loach
Give peppered kuhli loaches a tank of 20 gal (75 L) or more, with fine, soft sand and dense cover. Set it up as standard blackwater, with leaf litter, driftwood, shade and gentle flow.
Keep the water warm and acidic, at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.0. Feed them once the lights are low. Sinking foods and frozen bloodworm, daphnia and brine shrimp keep them in condition.
A band of six or more settles far better than one or two, and a generous group looks most natural. They will happily share a tank with other Pangio.
The peppered kuhli loach is peaceful and poses no threat to anything it cannot swallow. Pick small, quiet companions such as Boraras, small rasboras and dwarf gouramis. No dependable aquarium breeding has been reported.
Good to know
The peppered kuhli loach, Pangio piperata, is a slender eel-loach in the family Cobitidae. Its fine dark speckling takes the place of the bold bands of a typical kuhli. That peppered pattern is the easiest way to pick it out from its banded relatives in a mixed group.
In the wild
The peppered kuhli loach lives in soft, slow lowland waters of the Malay Peninsula and Sumatra. It is found in forest streams, swamps and backwaters stained dark with tannins. In nature, these loaches gather in large numbers.
