Was not placed in any genera at one time and was formerly
known as Ancistrinaesp.(L269)
but Chamon et. al. as of 2014 described this species
in their paper as Spectracanthicus immaculatus.
Dorsal soft rays (total): 8; Anal soft rays: 5; Vertebrae:
26. This species is distinguished from all species
of Spectracanthicus by its colour pattern
consisting of a dark grey body, without dots or spots,
and by having very slender teeth (vs. with small to
mid-sized yellowish dots in S.
murinus, and S. tocantinensis;
and large white spots in S.
zuanoni. This can be further differentiated
from S. punctatissimus and S. zuanoni
by having pointed snout in dorsal view (vs. snout
rounded). Additional characters useful to separate
this species from other congeners include the following:
nasal quadrangular (vs. nasal L-shaped); posterior
margin of pterotic-supracleithrum without contact
with posterior margin of orbit (vs. with large contact
with orbit in S. murinus and small contact
in remaining species); cartilage area of basipterygia
short (vs. elongate in remaining species, except in
S. murinus); anterior fenestrae of cartilage
area of basipterygia large in size (vs. small to median
size in remaining species, except in S. tocantinensis)
Aquarium Care: Peaceful, but they
do have a requirement for higher oxygen and prefer
currents in the water with a powerful filter. Sexual
Differences: Males have a longer and broader
head and a heavier growth of odontodes. Diet:
Carnivores and feed on snails in their natural habitat.
Feed live and frozen foods such as brine shrimp, mysis,
mussels and fish flesh. Tablet foods can also be fed.
