This species occurs in the
Amazon river basin in Peru (Ortega et al. 2012). Carvalho
et al. (2009) found it in a stream of the Upper Yuruá
River. Its type locality is the Ucayali River in Pucallpa,
Peru (Reis 1997). Unlike all other genera of subfamily
Callichthyinae, the species of Lepthoplosternum
are absent in the northern portion of the South American
continent, north of the Rio Amazonas. The species
are found in the upper Rio Amazonas in Peru (L.
altamazonicum), middle Rio Madeira and the Madre
de Dios, Peru (L. beni), Rio Paraguay (L.
pectorale), and in the laguna dos Patos drainage
(L. tordilho) in southern Brazil (Roberto E.Reis).
Aquarium Care: Peacfull species which
will do well in a planted tank with free swimming
place. They can be quite easily housed in your planted
community tank as they don't grow as large as thoracata
or littorale and don't show any aggressive
tendencies. Breeding: This small
species is a bubble-nester, where the female deposits
her eggs in floating plant material or a floating
polystyrene lid. Will attempt to spawn in a community
setup, but if they do it would be a good idea to move
the pair to their own breeding tank to make sure that
the spawning is successful, in that the fry will survive
the attentions of the rest of the tank inmates. Males
have thicker pectoral spnes. To read a report on breeding
this genera you can go to the breeding article
section for an indepth look at "how to do it".
Diet: As with most "Hoplo's" a
good varied diet of frozen, live and a good quality
flake food. It will eat most things given and of course
keeping up the water changes. Remarks:
Caudal peduncle comparatively deep (19.3–23.8%
SL); body and fins dark, with darker dots especially
Upper Amazon River drainage in Peru; range extended
to the area of confluence of the Rio Solimões
and Rio Japurá, Brazil. Type locality:
Peru: Pucallpa: Río Ucayali.
