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

Corrientes, Argentina in the upper Uruguay river basin
