Dorsal soft rays (total): 8; Anal soft rays: 6. Spatuloricaria
tuira distinguished from all other congeners
except Spatuloricaria nudiventris by its
abdominal surface completely naked or rarely with
few, very small plates (vs. abdominal region covered
with plates) and by the absence of preanal plates
(vs. presence of one to four preanal plates). It can
be differentiated from S. nudiventris and
S. fimbriata by having five transversal dark
brown bands on the dorsal region (vs. four transversal
dark brown dorsal bands in S. nudiventris
and S. fimbriata) and by having dark-brown
irregular stripes on the dorsal region of the head
and predorsal area (vs. absence of such stripes in
S. nudiventris and S. fimbriata).
This species has the smallest males recorded among
species of Spatuloricaria, with mature individuals
ranging from 8.55 to 15.39 cm SL and seems to be the
only one in the genus where mature males are smaller
than mature females (the opposite is the case in other
species of Spatuloricaria). However, additional
materials of some of the other species are needed
to further verify these observations, (Fichberg et.al
on the bottom of medium to large rivers, in association
with rocky or sandy substrates in fast-flowing sectors.
Aquarium Care: The Spatuloricria
genera all grow to a considerable lengthand
are not the easiest Loricaria species to keep in the
home aquarium. Good water quality and a spacious tank
are a must and also the water needs to be well oxygenated.
Diet: A mixed diet, foods that will find
their way to the substrate including vegetables such
as lettuce, cucumber and cauliflower.
Tuira's Whiptail, Marbled Xingu
Brazil:Rio Xingu and the Rio Tapajós drainages.
