he Rineloricaria genera is by far the most
speciose in Loricariinae, and is widely distributed
on nearly the entire subcontinent, from Costa Rica
to Argentina, on both slopes of the Andes. The species
inhabit an extremely diverse array of environments.
Our factsheet of the month for May 2022 concentrates
on one member of this genus, the "Common Whiptail
The type species
for this genera is Rineloricaria lima Kner,
1853. The holotype from Brazil was probably lost according
to Natterer (Isbrücker, 1979). If the loss of
the holotype of R. lima is confirmed, a neotype
must be designated in order to permit all the necessary
clarifications for a detailed and much needed revision
of this genus. The characters given by Kner (1853),
although very detailed, are valid for almost all congeneric
species. Without the type locality, it is presently
impossible to decide which species represents R.

River basin: Venezuela and Colombia. Type
species from this genera is really quite challenging
and are sold often in aquarist stores and
auctions as Rineloricaria species.
You may never find out what the true specific
name is but if you can find out where they
originated from, such as Colombia or Venezuela,
you may have R. eigenmanni
and of course
theblack banding continuing on the
ventral surface would also
point to this species.
we have location markers for most of the Rineloricaria
species that we often see in the hobby. At
the time of this factsheet (May 2022) there
are 63 species of Rineloricaria described.
River basin: Venezuela and Colombia.Type
Slender body with no rostrum.
A postorbital notch is present. All dermal ossificatations
including scutes, fin spines and rays are covered
with odontodes, the body ridges being covered by somewhat
more prominent odontodes. The abdomen is covered with
a few scutes in front of the anal opening, covered
with numerous scutes on the posterior half, or completely
covered with several series of small pitelets. The
upper lip is narrow, the edge with short , rounded
papillae. A short rictal barbel is present. The strongly
bifid teeth are present in both jaws, those of the
upper jaw smaller than those in the lower. The dorsal
fin is located opposite or nearly opposite the origin
of the ventral fins and has a spine and 6 (rarely
5) rays. The anal fin has a spine and 4 rays.
Varies considerably from light
to dark brown with 5 to 6 black bars starting at the
insertion of the dorsal fin. These black bars continue
on the ventral surface. All fins have black bars and
the top of the head will sometimes sport a reticulated
pattern with further spots on the snout.
Care & Compatibility
An easy species to keep with
no excessive demands on water parameters. Provide
a sand substrate with hiding places such as pipes
are cavity brooders laying numerous green eggs (often
more than 100) that are laid attached to one another
in single layer masses in pipes, and are brooded by
males. Provide caves or pipe work where the females
will lay their eggs as in the wild they are laid in
hollow logs or branches. The male takes over the guarding
of the green coloured eggs and they hatch, depending
on water temperature, between 3 and 10 days.
Males show strong
secondary sexual dimorphism and develop ‘bristles’
along sides of snout, usually also on dorsum of pectoral
fin spine and rays, and often dorsum of head, on post-occipital
and predorsal scutes. (Isbrücker & Nijssen
1976a: pp. 110–111).
Omnivore. Vegetable food such
as cucumber and other various foods such as tablet,
flake and frozen.
Anal fin:The median, unpaired, ventrally located fin
that lies behind the anus, usually on the posterior
half of the fish.
Dorsal:The primary rayed
fin(s) on top of the body. Odontodes: Hair - like stuctures
on the body. Papilla:A small
fleshy projection, plural papillae. Pectoral fins: The paired fins just
behind the head. Rictal barbel: Pertaining to the
barbels on the corners of the mouth. Rostrum: Snout (usually applied to
long snouts). Scutes: Bony covering. Ventral fins: The paired fins, between
the pectorals and the anal fins.
