Taxonomy & naming
This is an undescribed form: no scientific name, authority or type material stands behind it, and its identity and range are not documented in the sources the atlas uses. L475 is an L-number, the coding system DATZ magazine began in 1988 for imported loricariids that could not be identified. Imperial Tropicals sells it as the L475 Nhamunda zebra pleco and says the name refers to the Rio Nhamunda. It describes the fish as one of many look-alike Hypancistrus that are hard to tell apart from related forms such as the Colombian zebra and the chocolate zebra, and says they commonly hybridise with other species within their natural range in that river.
Morphology
Imperial Tropicals describes a dark grey, black or brown body covered in a pattern of lighter lines, shared with its look-alikes. Hypancistrus are small, compact, patterned plecos (genus-level).
Habitat
The seller names the Rio Nhamunda, a tributary of the lower Amazon in Brazil. Hypancistrus occur in rocky parts of South American rivers (genus-level).
Feeding
Hypancistrus are generally given meaty foods in the aquarium in addition to some vegetable matter (genus-level); this form's diet is not documented.
Mating
Hypancistrus are cave spawners in which the male guards the clutch (genus-level). Spawning of this form is not described.
Breeding
No captive-breeding record for this form is held by the atlas.
In the aquarium
Imperial Tropicals warns that identification within the zebra group is difficult and that hybrids occur, so a purchase labelled L475 is best bought from a seller who knows the source. No size, water or care figures are held beyond genus-level practice: clean, well-oxygenated water and cave hiding places.
Conservation
No IUCN assessment exists for this undescribed form. Its range and numbers are not documented, so its conservation status cannot be stated.
