way from the ongoing onslought of L-numbers we concentrate
this month on a species and genera that is not found
very often in the catfish hobby. Lamontichthys
llanero is currently shipped out of Colombia
on a regular basis, but never under it's correct name.
Usually it is traded as a Sturisoma species.
There are now
6 species (2010) in this genus with L. avacanoeiro
and L. parakana being added in the 2009 paper
by de Carvalho Paixão & Toledo-Piza. The
other four are L.
Monte, 1035), L. llanero Taphorn & Lilyestrom,
1984, L. maracaibero Taphorn & Lilyestrom,
1984 and L.
& Nijssen, 1978. They can be identified by their
round head, deep body, flattened caudal peduncleand the seven divided soft pectoral fin rays
which is inclusive to this genera.

This genus are
not the easiest to keep in captivity as they will
need to be fed on the right vegetarian food such as
algae paste on flat stones which can be a bit of a
hit and miss so would need to be tried on other veg
foods and also frozen foods and other aquarium prepared
foods. Water quality is also very important as any
lapse such as deficient oxygen content will prove
detrimental to this species. Will spend most of their
time attached to the aquarium glass sides and will
be difficult to feed as they will only move to the
substrate for a few moments. If kept with other Loricaria
species such as Sturisoma they will have
to compete for food and they will eventually lose
out. A Loricariid for the experienced catfish keeper.

are quite active , who constantly move around in their
aquarium on the search for food. Older, bigger specimens
appear much more elusive and shy. The rumour of them
being difficult to maintain may be caused by their
poor condition once they arrive in the trade and then
onto the aquarist who may struggle with them in this
llanero has been
collected near the margins of rivers varying from
less than 10 m until 1 km of width, in areas with
muddy waters, and sand or mud in the bottom.

head, deep body, flattened caudal peduncleand the seven divided soft pectoral fin rays
which is inclusive to this genera. Caudel filaments
very long and a high dorsal.
Eight to nine brown bands on
a cream body colouration. All fins with brown bands.
Dorsal with black leading band going right to the
tip. Caudal filaments with brown edgings one quarter
the length from the caudal peduncle.
Care & Compatibility
Would need a good sized tank
for a group with a sandy bottom or with no substrate
and good water movement. With no substrate they will
tend to move to the ground and can be fed easier.
Provide driftwood and rocks to mimic there natural
habitats. Possible tankmates could include peaceful
characins and other mid to surface non aggresive species
that can tolerate water movement but probably would
do better kept on their own so feeding could be easier.
The breeding of
this genera has been achieved but the raising of the
fry has been problematic. Eggs were scattered on the
aquarium floor and the fry did not survive in two
spawns due to difficulty in feeding them. The next
few spawns were a bit more successful due to sterile
conditions and the feeding of flake food. (M. Hemmann
Males tend to
have odontodes (hair like structures) on the first
ray of the pectoral fins and the head in males is
Vegetable and meat based foods.

The tail. Caudal peduncle:The narrow part of a fish's body to which
the caudal or tail fin is attached.
Dorsal fin:The primary
rayed fin(s) on top of the body. Odontodes: Hair - like stuctures
on the body. Pectoral fins: The paired fins just
behind the head.
