Apistogramma viejita „Gold“

202009/api%20viejita%20gold%20mann1.jpg> 

For the first time we can offer now this beautiful dwarf cichlid in a golden
sport. This sport does not occur in nature. The contrasting golden and red
colours make the fish extremely attractive.

202009/api%20viejita%20gold%20frau.jpg> 

As Apistogramma viejita originates from Colombia it should be kept at higher
temperatures as usual, eg 26 – 28°C. Water should be clean, soft and
slightly acidic.

Lexicon: Apistogramma: from ancient Greek, meaning „with unreliable line“.
It is not known wether this refers to the lateral line or the dark lateral
stripe displayed by many species. viejita: diminutive of the Spain word
vieja, meaning crone. Vieja is a term given to cichlid species with brood
care in Spanish speaking parts of Latin America.

Corydoras narcissus 

<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2034%
202009/narcissus%20zusam.jpg> 

Corydoras narcissus is a beautiful, relatively large species of Corydoras
from Brazil. The maximum length is given with 10 cm. In Brazil, the species
occurs in the Rio Purus system. C. narcissus belongs to the group of
Corydoras with a saddle shaped snout. Like all members of this group it is
not a schooling fish at all. Breeding has not been described yet in
literature, but in any case one needs large tanks and has to look for the
fish carefully, as saddle snouted Corydoras are known to become very
aggressive during mating from time to time.

<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2034%
202009/IMG_1432.JPG> 

The unusual name was given to the beautiful and (despite mating) peaceful
species because the collectors wanted the scientists who described the
species as new to name the new fish after them (the collectors). This
impudently attack against the freedom of science was not acceptable for the
describers. So they named the fish after the Greek half god Narcissus who
fell in love with his own mirror image. Since that time the name of
Narcissus is a synonym of excessiv self-love.

A second, quite similar species is imported from Peru. This species is still
undescribed scientifically. It is called C. narcissus II in the hobby while
the original species is called C. narcissus I by aquarists. This is a bit
confusing, because both species are not close relatives to each other and
for sure will become placed even in different genera on the day the
catch-all genus Corydoras becomes revised. C. narcissus II belongs to the
long snouted group of Corydoras. It does not grow as big as C. narcissus I,
the body coloration is rather flesh-coloured (whitish in C. narcissus I), it
has a transparent dorsal spine (black in C. narcissus I) and the black
stripe over the back ends at the eye (runs over the snout in C. narcissus
I).

<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2034%
202009/IMG_1437.JPG> 

So it is quite easy to distinguish both species even without knowing their
origin.

For our customers: C. narcissus I has code 237104, C. narcissus II 237204 on
our stocklist. Please note that we exclusively supply to the wholesale
market.

Lexicon: Corydoras: from ancient greek, means „with helmet and spear“. This
refers to the strong armor and fin spines. narcissus: after the Greek
half-god Narcissus, who fell in love with his own mirror image.

Betta cf. imbellis „Vietnam Black“ 

<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2034%
202009/cf%20imbellis%20mann.jpg> 

We import from Vietnam a pretty wild collected Betta for some time now. The
exact determination of that species proofed to be quite complicated. There
are four scientifically described species from this complex: Betta imbellis,
B. smaragdina, B. splendens, and B. stiktos. An additional species is
already known in the hobby as B. sp. „Mahachai“, which looks very similar to
B. smaragdina.

Betta splendens is one of the most enigmatic specie of fish at all. Back in
1910 the scietific decrition based already on domesticated animals. This is
comparable as if the species „wolf“ would have been described on the basis
of a Yorkshire terrier and one would now try to reconstruct the appearance
of the wolf on the basis of the scientific description. So nobody on earth
really knows what exactly B. splendens is. Pragmatically speaking both
species are distinguished from each other in the hobyy by the coloration of
the operculum in males. Males of B. splendes develope two bright red stripes
on the operculum, whereas B. imbellis males have shining spots on the
operculum.

<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2034%
202009/cf%20imbellis%20frau.jpg> 

Our Vietnamese fish were initially termed Betta imbellis on the basis of
this. Some time later the scientific description of B. stiktos was
published. Checking our fish again, we found that they had the
species-specific spots described for B. stiktos. However, after all
experience, we know that preserved material does not allow to distinguish
species reliably in Betta. Nevertheless we decided to rename our fish to
Betta cf. stiktos. Some time later, aquarists made a trip to the type
locatlity of B. stiktos and were able to collect the species alive. Now it
became clear that our fish had nothing to do with it, as B. stiktos looks
almost identical to B. smaragdina.

The Vietnamese fish is distinguoished from most other varieties of Betta
imbellis by the lack of green or blue shing spots on the flanks. Thus
displaying males look deep black. We now have renamed them to B. cf.imbellis
to make clear that they are not identical to the fishes often imported from
the malayian region.

<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2034%
202009/kiemenhaute.jpg> 

What name applied to the fish in the future will be the correct one cannot
be predicted, but one thing is for sure: B. cf. imbellis are beautiful fish
which fit deally in any well planted community tank with peaceful tankmates.
Like in B. imbellis and B. smaragdina keeping more than one male per tank is
possible.

For our customers: The fish have code 391023 on our stocklist. Please note
that we supply to the wholesale trade only.

Lexikon: Betta: after an indigenous Indonesian term for one of the species.
imbellis: Latin for „peaceful“. smaragdina: Latin for „emerald colored“.
splendens: Latin for „splendid“. stiktos: ancient Greek for „spotted“.cf.:
from Latin „confer“ which means „compare with“.
