Description: Hisonotus charrua is diagnosed by the following combination of characters, lateral plates 23-25, posterior margin of pectoral spine smooth, 18 to 24 plates 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. Etymology: The specific epithet charrua is the name of the aborigines that lived in the Uruguayan coast of the Rio de la Plata; a noun in apposition.
