Described
from tributaries of the lower course of río Putumayo in Peru,
close to the border with Brazil and Colombia. Related to Corydoras
reynoldsi, C.
weitzmani, C.
panda and C
.tukano, all of which share
a pattern composed of uniform light ground colour on body, dark
bar (“mask”) across orbit, and one or two large rounded
blotches midlaterally on trunk. C. ortegai is easily distinguished
from these species, except C. panda, mainly by the absence
of a midlateral trunk blotch at the dorsal-fin level, and the rounded
shape of the midlateral trunk blotch at the adipose-fin level. It
also differs from C. panda by its greater number of lateral
body plates, lack of dorsal-fin blotch, scattered chromatophores
surrounding midregion of cleithrum, caudal fin with series of small
blotches restricted to rays, slenderer body, and narrower intercleithral
area. C. ortegai belongs to a putatively monophyletic assemblage
of Corydoras that occurs mainly in the Western Amazon basin,
C. tukano excepted. The occurrence of C. tukano
in the Rio Tiquié (upper Negro basin) and its putative sister
species, C. ortegai, in the western Amazon, together with
similar distribution patterns shared by other groups of fishes,
suggest a biogeographic relationship between these areas. Occurs
mainly in lotic habitats characterised by muddy-brown colour, soft
bottom of clay and sand where it is relatively abundant. Aquarium
care: This is akin to most of this
genus, very peaceful, and would be best housed with small to medium
tank mates such as Tetras, Rasboras and Danios or
in a species tank for breeding purposes. Diet:
A good quality flake food and tablet food
for adults with sporadic feedings of frozen or live food will keep
your Corydoras in good health. |
