ormerly
of the Hemiloricaria genera this months factsheet
(August 2014) boasts one of the prettiest members
of the Hemiloricaria/Rineloricaria
complex. Alongside R.
formosa
these two stand out from the run of the mill brown
and beige specimens that we are all accustomed to
in the hobby and in our local LFS.
Rineloricaria
lanceolata
The
name is sometomes accepted in some quarters as Hemiloricaria
lanceolata. Issbrücker (Issbrücker
in Issbrücker et al, 2001) declared the synonymity
of Rineloricaria and Hemiloricaria
as no longer valid, and the latter again as an independent
genus. The differences between the two genera are
based on the positions of the males bristles and the
top caudal filament on adult Hemiloricaria
which is absent on Rinelolricaria.
Rineloricaria
lanceolata
- head view
R. lancelota
is cataloged as coming from the upper Amazon basin
in Peru but the truth of the matter is that it is
found in various guises all throughout South America
and as such the colouration is highly variable.
Depending on the
origin of catchment, temperature values would differ
from the upper Amazon to the more southerly specimens
which would require lower values. The species depicted
in the images is the species from the Rio Huacamayo
in Peru which in my mind is the most striking of the
varieties.

(depending on origin)
p.H.

Characteristics
Typical species specific slim
shape. Ventral area covered with scutes. Upper caudal
fin ray greatly extended.
Colouration
Colour pattern highly variable.
Ground colour pale tan. Dorsum of head with medium
tan area from tip of snout to base of dorsal fin
spine. Two thick chocolate
coloured lines run on either side of this tan area
running through the eyes and
terminating at the base of the dorsal fin. This
line resumes and
is thinner and may reach the
full length of the body depending on the species.
There is a thick chocolate band to the front of
the dorsal fin.
Aquarium
Care & Compatibility
Reported
as quite an easy species to keep and breed although
it is prone to eating the eggs, so the eggs would
need to be hatched separately.They can be bred in
pipes in the aquarium with a 5-7cm diameter. Peacefull
species which can be kept with most unagressive fishes
in a mid to large aquarium. Best
kept in pairs although two males will get along fine
with each other.
Reproduction
Orange eggs are
laid in pipes. The males tend the spawn over a 12
day period. Sometimes the males will eat the eggs.
If successful the fry can be raised with good water
hygiene and the feeding of Artemia nauplii.
Sexual
Differences
The males have
cheek, head and pectoral bristles. The
females lack them and tend to have a more pointed
head.
Diet
Omnivore.
Vegetable food such as cucumber and other various
foods such as tablet, flake and frozen.
Glossary
of Terms
