Loricaria pumila is a small, slender whiptail catfish endemic to the lower Amazon basin. Named for its dwarfish size, it rarely exceeds 8cm. It is a highly camouflaged, peaceful bottom-dweller that inhabits deep river channels over silt and organic detritus. In the aquarium, it requires a soft sand substrate to sift through, along with driftwood and leaf litter. Unlike plecos, it is an omnivorous micropredator and detritivore, feeding on small insect larvae rather than relying heavily on algae or wood.

A slender, highly camouflaged whiptail catfish native to the deep, blackwater river channels of the Rio Negro and Rio Madeira basins. Unlike many suckermouth catfish, they are primarily insectivores and detritivores, actively sifting through the substrate for aquatic insect larvae rather than eating algae. They are peaceful, facultative air-breathers that require a soft sand substrate to prevent damage to their delicate mouths.
Loricaria spinulifera
Loricaria spinulifera
Loricaria spinulifera, sometimes known as the Spiny Whiptail Catfish, is a highly camouflaged, slender bottom-dweller endemic to the deep river channels of the Amazon and Rio Negro basins.
