species in the current importation also
exhibit a whole multitude of color
variations: individuals with or without
shoulderspot,withorwithoutstripesonthe
caudal peduncle. Note that the strongly
metallic green-golden sheen exhibited by
freshly-imported specimens disappears
over time in theaquarium.
However, another saddle-nose (list name
"manu 6 batman") is clearly distinct from
C115/116 by virtue of its unpatterned fins.
Thisone isdefinitelya first import.Moreover
in thisspeciesof themale– recognizableby
the much-thickened pectoral spine - is
precisely the same sizeas the female,while
in "manu1,4,7,8" themale is considerably
larger than the female.The "Batman"canbe
regarded as the saddle-nose variant of a
gorgeous metallic mailed catfish from the
Madre de Dios that is imported under the
trade name "
Corydoras aeneus
Puerto
Maldonado".PuertoMaldonado isaporton
the Madre de Dios. At present all metallic
mailed catfishes are repeatedly lumped
together under the catch-all species
Corydoras aeneus
, although this is certainly
incorrect. The group is in urgent need of
revision. The "Puerto Maldonado" belongs
to the Gold Shoulder group of mailed
catfishes, formerly known as
Corydoras
schulzei
. In addition to the gold-colored
shoulder stripe the Puerto Maldonado
exhibits a large dark spot on the anterior
halfof thebody, just like the "Batman".
The attractive
Corydoras
sp. C91 has been
available for some time, albeit irregularly
andonly in small numbers.This species is a
typical
round-nose,
similar
in
its
maintenance to the species
Corydoras julii
and
C. trilineatus
, with which C91 is
undoubtedly closely related.And the long-
nose equivalent of C91 has now been
imported for the first time as well.
Unfortunately we have no information on
the collecting location for these fishes.C91
supposedly comes from theRioHuallaga,a
roughly 1,100 km long tributary of the
Maranon,which in turn is the larger of the
two headwaters of the Amazon. The
