Alternative names
Coolie Loach, Kuhli Eel
Native range
Southeast Asia; P. kuhlii is recorded from the Sunda region.
Natural habitat
Slow forest streams and soft-bottomed waters with leaf litter and dense cover. Use sand, leaves, wood and gentle-to-moderate flow.
Diet & feeding
Feed small sinking pellets and varied frozen/live foods after or near lights-out. Ensure food reaches hidden fish.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
Sexing
Females become broader through the abdomen when mature; males may have more developed pectoral-fin rays, but sexing is subtle.
Breeding
Egg layer; aquarium spawning is uncommon and poorly predictable compared with common livebearers or Corys.
