Dorsal spines (total): 2; Dorsal soft rays (total):
7; Anal soft rays: 5. This species can be distinguished
from Lasiancistrus heteracanthus and L.
guacharote by having no plates on the abdomen;
differs from L. schomburgkii by having large
white spots on the head (vs. small white spots), with
plates of the body outlined in black (vs. entire body
uniformly dark), and absence of spots in the dorsal
and caudal fins (vs. usually with small white spots);
differs from L. tentaculatus by having whiskers
on the snout of nuptial males (vs. tentacules longer
than their associated odontodes); and from L.
caucanus and L. tentaculatus by lacking
dark spots in the dorsal and caudal fins (vs. with
dark spots). Habitat: Lasiancistrus
saetiger is known from a single collection of
fishes from the rio Guamá, a tributary of the
rio Capim, a drainage that enters the Atlantic just
southeast of the mouth
of the Amazon. Aquarium Care: Relatively
easy to keep but large males may tend to be territorial.
Sexual Differences: Males have longer
pectoral fins and have a heavier growth of odontodes
behind the gill covers and on the edges of the snout.
Diet: Omnivore. Pretty similar to
the Ancistrus genera with a vegetable diet.
