Hemiancistrus is also known in some literature as Ancistomus but is also similar to the Peckoltia genera but has a longer body and a naked ventral region. Habitat: H. votouro is found in a 2-5 m wide stream, with rocky and sandy bottom, small rapids separated by pools and marginal vegetation moderately preserved. Description: Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays: 4. Distinguished from all other species of Hemiancistrus except H. chlorostictus, H. meizospilos, H. megacephalus and H. macrops by the presence of light dots on all fins and the lateral and dorsal portions of body. H. votouro differs from H. chlorostictus by having more premaxillary teeth (61-79 vs. 30-54), larger adipose-fin spine (9.0-10.4% SL vs. 5.8-8.0% SL), deeper caudal peduncle (11.0-11.8% SL vs. 9.6-10.4% SL), larger pectoral fin (36.2-41.3% SL vs. 30.6-35.4% SL); larger exposed portion of cleithrum (11.2-12.7% SL vs. 9.3-10.6% SL), narrower body at dorsal-fin origin (17.9-19.8% SL vs. 19.9-25.3% SL) and first anal-fin pterygiophore not exposed (vs. exposed). H. votouro differs from H. meizospilos by the smaller orbit diameter (14.5-16.7% HL vs. 16.7-21.0% HL) and much smaller light markings (one to three dots per plate vs. one large dot occupying one to three plates and skin between them). H. votouro is distinguished from H. megacephalus and H. macrops by the number of the light markings per body plate (one to three small dots per plate vs. only one large dot on each body plate). Aquarium Care: Good aquarium habitants for a medium to large tank and you can also house more than one species. They like water movement in the aquarium. Diet: Mainly a vegetarian diet but can also be fed tablet foods and frozen and live foods such as mosquito larvae, brine shrimp and shrimps. Etymology: The specific name votouro: Named for the Votouro Indian Reserve, situated on Benjamin Constant, Rio Grande do Sul, Brazil, type locality. Remarks: Hemiancistrus votouro is endemic to Brazil, occurring in the upper portion of the Uruguay River basin and in the Toropi River. The species is frequent and abundant, and as no significant threats have been detected that put its population at risk, Hemiancistrus votouro has been categorised as Least Concern (LC), (IUCN 2022). |
