Distinguished from its congeners by a unique combination
of characters: two unpaired median pre-dorsal plates,
body width 10.0-13.0% of post-dorsal fin length, inter-orbital
distance between 10.6-13.0% of post-dorsal fin length,
inter-orbital distance between 25.0-29.0% of eye-to-dorsal
fin length; low number of jaw teeth (12-15 teeth in
upper left jaw, 9-13 in lower left jaw), and pre-dorsal
fin body pigmentation not formed into distinct lines
between longitudinal rows of odontodes. Aquarium
Care: Will need a fairly strong current in
the aquarium. Not the easiest to care for so really
a catfish for the more experienced Loricariid keeper,
so would be better in a species tank on their own.
Diet: Fine Vegetarian foods especially
algae and small meaty foods such as brine shrimp nauplii.
They rarely sit on the substrate but on leaf stalks
and branches so they are especially difficult to feed.
