n reaching our 200th
factsheet on ScotCat we are returning to arguably the most popular
of the catfish families, namely the sub-family Corydoradinae and
the growth, which seems weekly, of the unidentifiable new catches
which are culminating in the CW numbers which have basically taken
over the mantle left by the C-numbers of the German Magazine,
Datz. These CW numbers have of course started online and originate
from the Corydorasworld
web site of Catfish
Study Group President Ian Fuller.
The tenth unidentified Corydoras
species is of course the beautiful CW010 from Peru commonly known
as the "Gold Laser" (sometimes referred to as the Orange
laser) which can be seen in the above picture showing the gold
shoulder stripe starting from the nape of the head and ending
at the caudal peduncle. Similar to CW009
(Green laser) but this species has a yellow shoulder stripe and
a light greener body.
May yet prove to be a variant of Corydoras
aeneus but these aeneus variants need
to be worked on by the scientists to determine one way or another.
Imported as Corydoras aeneus "Gold laser" there
are a few aquarists who think that this species is nearer Corydoras
melanataenia than C.aeneus but as stated earlier
work needs to be done on these "Laser" Cory's.
Can be a secretive species and will do
better if given plants or other shelter to hide away in.
Dorsal 1/7; Anal 1/6-7. Stocky built Corydoras.
Ground colour yellow with yellow fins.
Gold shoulder stripe starting from the nape of the head and ending
at the caudal peduncle, sometimes this stripe is all gold and
in other specimens there can be yellow further along on this stripe.
Dark green mid body band running along the full length of the
body. Gold patch on the operculum.
This is akin to most of this genus, very peaceful,
and would be best housed with small to medium sized tankmates such
as Tetras, Rasboras and Danios or in a species tank for breeding
purposes. Best to purchase 6 individuals or more as they will be
happier in a group.
Lays eggs in batches on the glass and plants
in the aquarium. The best for breeding ratio would be one male
to two females if given the choice.The first sign of intending spawning
activity is when you see the female with a heavier girth. If kept
in a community tank it would be better to house the specimens in
a species tank set up with the same water parameters as the main
tank. You can carry out 50% water changes
in this tank once or twice a week to encourage spawning.
