Spectracanthicus punctatissimus can be distinguished
from all congeners by having 12-14 vertebrae from
first neural spine not including hypural plate (vs.8-11
in remaining species). It further differs from its
congeners (except from S.
having yellowish bars on tip of dorsal and caudal
fins; from S. immaculatus and S.
zuanoni by having small yellowish
dots covering body (vs.colour pattern uniform, with
no dots or large white spots, respectively); and from
S. tocantinensis by having the rounded dorsal
profile of snout (vs.snout pointed). Spectracanthicus
punctatissimus differs from S. murinus
by presence of a bar-shaped eversible opercle with
conspicuous odontodes (vs. triangle-shaped opercle
not eversible, without conspicuous odontodes) and
by the presence of 4 unbranched anal-fin rays (vs.
3 anal-fin unbranched rays). Aquarium Care:
Should be no problem in the aquarium but would need
a strong current and oxygen rich water due to the
high temperatures enjoyed by this genus. Sexual
Differences: Males have a longer and broader
head and a larger growth of odontodes behind the gill
covers and on the pectoral fin spines. Diet:
Omnivore. A varied diet with both vegetable and other
foods such as tablet and frozen. Remarks:
As of 2019, L016 and L315 are now believed to be this
species and also the genus of Oligancistrus
is now a synonym of Spectracanthicus.
