This species has the following characters: pigmented
body; functional eyes; dorsal fin base 14.4-19.4%
of SL; origin of adipose fin anterior to the anus;
maxillary barbels extend beyond pelvic fin origin;
adipose fin insertion closer to the dorsal fin than
to the caudal fin. Colouration: Brown
body with a distinct lateral longitudinal dark band.
Rhamdia guatemalensis occupies
main channel of rivers and streams, either with turbid
waters and high sediment loads or with transparent
waters and few nutrients. It prefers pools and slow-flowing
waters of different depths and has plant material
deposits and heavy substrates such as rocks and stones
which serve as shelter for this fish during the day.
Aquarium Care:Treat 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.
