species is common in the Guayas, Chone, Portoviejo
and Esmeraldas basins of western Ecuador.
Description: This species is distinguished
from other catfishes by having the anterior surface
of pectoral-fin spine without hooks, a prominent dark
brown stripe present laterally, maxillary barbells
extending well past the adipose-fin origin, and caudal-fin
lobes of equal length (Glodek, 1978). This genus has
been in confusion for a good number of years now especially
with another close member of the Pimelodidae family,
Pimelodus. These notes are the following distinguishing
characteristics from the two genus. Pimelodella:
Adipose fin long, low with a curved margin. The
humeral process is long and spiky. Body usually plain
with a dark lateral stripe; rather depressed body.
Pimelodus: Adipose fin short, high,
with a straight or sloping margin. Humeral
process broad, triangular. Body variously patterned,
usually quite deep, like the African genera Synodontis.
as you would do with any member of the Pimelodus in
that they will be predatory on small fishes in the
aquarium and it is also better to keep them in small
groups rather than singularly, as this will dilute
the aggression. Diet: Will eat any
aquarium prepared foods such as tablets, pellets,
frozen and live foods. Not fussy eaters. Remarks:
Can still be found on some online searches as Pimelodella
