|Scientific Name||Hemiancistrus guahiborum Werneke, Armbruster, Lujan & Taphorn, 2005|
|Common Names||L106, Spotted Orange Seam Pleco|
|Type Locality||Río Ventuari at raudales Tencua 56 km ESE of San Juan de Manapiare, Venezuela, Amazonas, 05.04968°, -065.62722°.|
|Etymology||Greek, hemi = the half. While the Greek, agkistron = hook, is thought to be the root of the term ancistrus, hemiancistrus can be taken to mean that these species have a part (not exactly HALF) of the features of the genus Ancistrus, but not ALL of the features. Named for the Guahibo, a tribe of people inhabiting parts of southern Venezuela and western Colombia for the help some members of the tribe provided in collecting specimens in the upper río Ventuari.|

|Temperature||25.0-31.0°C or 77-87.8°F (Show species within this range)|
|Other Parameters||Natural habitat: Rocky region of river, heterogeneous structure consisting of porous rocks interspersed with solid rocks. Example, the Rio Bita: Average temperature, 30.9 ± 0.3°C (maximum, 31.1°C; minimum, 30.1°C), highly oxygenated (8.2 ± 0.1 mg O2/L), and slightly acidic (pH 6.6 ± 0.1).|
|Feeding||Gut analysis indicates a diet consisting at least partly of bloodworms and other insect larvae/pupa.|
|Furniture||The natural habitat of this fish is crevices on rocky bottom.|
|Breeding||Unreported in captivity. In nature, breeds year-round; gravid females (typically carrying 48 ± 19 oocytes, minimum 39, maximum, 143) and juveniles are found all months of the year. Evidence suggests that spawning is not triggered by environmental changes such as flooding-induced decreases in water hardness. Males guard nests.|
|Breeding Reports||There is no breeding report.|
