Aspidoras menezesi
Nijssen & Isbrücker, 1976 |

hese small 'Corydoras type' fish from the
Callichthyidae family are very similar to Corydoras
but are smaller and slimmer with smaller eyes and have one very
important distinct difference from the latter, of having a dual
fontanel (opening in the head bone), whereas the Corydoras
genus has a single fontanel.
To find out more about these differences you can go to The
Genus Aspidoras in the Ichthyology section of the
ScotCat articles page.
Identifying Aspidoras can be problematic as most of them
(apart from Aspidoras pauciradiatus) have body marking
of spots and blotches on a tan background and unless you know
the precise area in Brazil where they were collected it can be
very difficult. I have over the past few years taken drawings
of species I have kept, and also seen on the show bench, to differentiate
between each species, and will hopefully some day, to be able
to identify them from these sketches.
The picture depicted above shows what is believed to be A.
menezesi although the colouration is more golden with less
spots than the normal form. The fry of this form have black in
the leading rays of the dorsal fin and have carried this trait
into the juvenile stage.
Aspidoras
menezesi needs a little more
care to their husbandry than most Corydoras species, in
that the water parameters should stringently be adhered to, in
that regular water changes of the same chemistry to keep them
in good condition. These fish don't seem to do well in the hurly-burly
of a community tank and would be better placed in a species tank
with strong filtration and well planted, as they do tend to hide
and are nervous if there is no protection from the open spaces.
They also like the temperatures to be on the lower side of tropical
i.e. below 75°f.
If purchasing this nice little
catfish do buy at least four, (better six), as they do better
in their own company and tend not to sulk with their own kind
and of course you could have a better chance of breeding them.
Dorsal 1/7; Anal ii,5; Pectorals; 1/9; Ventrals
1/5. 26 Dorsolateral body scutes. 23 Ventrolateral body scutes.
6 pre-adipose scutes.
Row of elongate blotches along the side from
the gill cover to the caudal peduncle. The posterier blotches may
be united. The upper back is dusky, perhaps with some blotches or
showing a marbled pattern. The lower portion of the body is generally
unpigmented. The dorsal fin has some blackish markings and the caudal
fin is banded.
Inoffensive catfish which will suffer at the
hands of aggressive tank mates. Will
do well in a species tank or a community tank with smaller inmates
such as tetras and rasboras. Best to keep in a shoal of at least
four.
Has been bred. Similar to Corydoras
in this respect but they do tend to eat their eggs, so removing
parents or eggs after spawning is a good idea. They lay their eggs
in Java moss or on the aquarium glass and you can raise the young
as per the Corydoras genus.
Prefer live food such as newly hatched brine
shrimp but will also take frozen food and good quality flake food,
plus tablet food.
