Peckoltia lineola can be identified from all
other Peckoltia except P.
cavatica, and P. vermiculata
by having vermiculations on the head and snout. Peckoltia
lineola can be identified from P. braueri,
P. cavatica, and P. vermiculata by having
thick vermiculations almost as wide as the pupil on
the compound pterotics and snout (vs. thin vermiculations
much narrower than the pupil diameter and by also
having large spots on the compound pterotics and snout
(vs. no spots); from P. braueri and P.
cavatica by lacking an orange band in the dorsal
fin; from P. cavatica by having the vermiculations
cross the bones like the compound pterotic (vs. dark
lines only outlining the plates and bones of the head);
from P. caenosa by having dark bands in the
fins (vs. light spots), by having long, thick, longitudinal
lines on the abdomen (vs. vermiculations with a random
orientation), by having the light interspaces on the
snout of about the same width of the black spots and
lines (vs. light vermiculations narrower than dark
ones), and by having the light bands of the caudal
at least 50% width of dark bands (vs. 25%); and from
P. vermiculata by not having the vermiculations
coming from a central point on the parieto-supraoccipital.
Peckoltia lineola is similar to P.
brevisexcept that some of the spots on the head and
snout combine to form lines (vs. all spots separate)
and the spots on the abdomen combine to form long,
thick longitudinal lines (vs. spots separate). Aquarium
Care: Should be kept at slightly higher temperatures
and have a requirement for a higher oxygen intake.
Peacfull inhabitants of an aquarium. Sexual
Differences: The main collection consisted
of only nuptial males. Nuptial males with hypertrophied
odontodes on sides and posterior part of head; hypertrophied
odontodes becoming larger posteriorly. Hypertrophied
odontodes on upper caudal-fin spine and adipose spine.
Upper caudal-fin spine thickened. Odontodes on pectoral-fin
spine not noticeably larger. Remarks:
