lanceolata (Günther, 1868)
This very nice looking species is still
listed in Fishbase and the Catalog of Fishes as Rineloricaria
lanceolata but the name is currently 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and Hemiloricaria as no longer valid, and the latter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
ormerly of the Rineloricaria
genera this months factsheet (August 2014) boasts one of the
prettiest members of the Hemiloricaria/Rineloricaria
complex. Alongside H.
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.
H. 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.
the mouth and bristles
Typical species specific slim shape. Ventral
area covered with scutes. Upper caudal fin ray greatly extended.
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.
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
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.
|The males have cheek,
head and pectoral bristles. The
females lack them and tend to have a more pointed head.
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.
Vegetable food such as cucumber and other various foods such as
tablet, flake and frozen.
Lance-like, spear-like; armed with a pointed weapon.
The upper (dorsal) surface
of the head or body.
