Description: Dorsal spines (total): 1; Dorsal soft rays (total): 7-8; Anal spines: 1; Anal soft rays: 5. Can be distinguished by the following combination of characters: presence of heavy serrae along complete posterior pectoral spine margin; presence of narrow odontode free area along anterior margin of snout; anal fin with 5 branched rays; lateral line canal incomplete and discontinuous with an anterior field bearing 2-7 pores and posterior field with 8-19 pores. Habitat: Found in between aquatic plants (species of Ludwigia and Potamogeton) and on leaves of terrestrial plants hanging into the water. Occurs in a small, shallow creek with muddy soil and clear, slow-flowing water and also in creek with regions of rapid and slow flowing water, with loose stones, and gravel at the bottom and with dense vegetation in the margins. Reproduction: Scatters eggs throughout the aquarium and are not cared for by the parents. Aquarium Care: Said to be a bit more problematic in the aquarium if good water quality is not adhered to. They rest on aquatic vegetation in the aquarium so long leaved plants are recommended. Cooler temperatures and a strong filtration with adequate current will fare better for this species and for this genera overall. Diet: Will feed on flake, algae, tablet foods and algae wafers. Etymology: ringueleti; From the Spanish word candombe, referring to the African derived rhythm that was popularised in the nineteeth century by black slaves in the República Oriental del Uruguay. Remarks: The species depicted could be H. ringueleti or a very close relative (H. cf. ringueleti). It was captured by the image contributor in early 2016, in a urban sewer in the town of Yapeyú Corrientes, Argentina in the upper Uruguay river basin near to the border with Uruguay.
