Hisonotus charrua is diagnosed by the following
combination of characters, lateral plates 23-25, posterior
margin of pectoral spine smooth, 18 to 24plates bearing laterosensory canals, snout
with an anterior odontode free area, and caudal peduncle
depth 10.8-12.3% of SL. Colouration:
Ground colour of dorsolateral body surface brownish,
ventral surface of head and trunk pale brown. Narrow
light stripe from snout tip to eye. Dorsum of body
and upper third of flanks light, this area extending
from supraoccipital margin to caudal fin. Pectoral,
pelvic, dorsal, and anal fins pale brown with dots
forming series of darker bands. Caudal fin dark brown
with light scattered dots, and two light vertical
bars; first one at about middle fin, second one narrower,
placed near distal margin and sometimes less evident.
Caudal fin with light area on tip of three or four
uppermost rays.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.
South America:Rio de la Plata basin, and the lower Uruguay
basin in Republica Oriental del Uruguay.
