Caros colegas,

 

Desta vez não há vivíparos e ovovivíparos na " newsletter " da Glaser, mas
como sempre anunciam-se algumas raridades.

Acredito que para qualquer aquariófilo há aqui propostas que não deixarão
ninguém indiferente.

 

Um abraço

 

Miguel

Pseudocrenilabrus multicolor victoriae

This extreme beautiful small cichlid has changed its name quite often.
Initially it was introduced to the hobby under the name Pseudocrenilabrus
philander dispersus. The natural distribution area of this subspecies is
Uganda.

Only bred specimens are traded. The fish are agamous maternal mouthbrooders,
which means that the males and the females do not build up pairs for a
longer period and that the female alone takes care for the brood. In
contrast to many other species of mouthbrooding cichlids the female even
picks up the freeswimming youngsters in case of a potential danger. This
unique type of broodcare belongs to the things every enthusiast should have
observed at least once in life.

Pseudocrenilabrus multicolor victoriae becomes sexual active at a length
around 5 cm, but very old specimens might reach even 10 cm. Usually the size
of fully grown fish is in between the two extremes, e.g. 7-8 cm. The tank
for Pseudocrenilabrus should contain parts with fine sand, for here the male
builds up the nesting pit. Plants become destroyed only in case they are in
the way. Pseudocrenilabrus are completely undemanding regarding the water
chemistry and food, keeping and breeding thus is pretty easy and can be done
even by beginners.

For our customers: the fish have code 566403 on our stocklist. Please note
that we exclusively supply the wholesale trade.

Lexicon: Pseudocrenilabrus: from ancient Greek, means "false Crenilabrus".
Crenilabrus is another genus of fish. multicolor: Latin, means "with many
colours". victoriae: refers to Lake Victoria, where the species occurs.

Pseudomystus siamensis (= Leiocassis siamensis)

202%202010/423603-siamensis%20mann.jpg> 

It has been some time that we had this good old fashioned classic from
Southeast Asia in our fishhouse. Pseudomystus siamensis originates from
Thailand, Cambodia, and Laos and is  a smaller species of catfish. Maximum
length given in literature is 15 cm, but this length is hardly ever reached.
Against congeneers and other species of fish the Asian Bumblebee Cat  is
quite peaceful as long as they are big enough. Otherwise they are taken for
food. The catfish feed on anything available, may it be dry, frozen or live
food. Although the fish are most active at dawn, they are comparably smart
and learn to come out of their hiding place at any time of the day when food
is given. Regarding water parameters the animals are completely undemanding.
Water temperature should be between 22 and 26°C. Plants are ignored.

Lexicon: Pseudomystus: Ancient Greek, means "false Mystus". Mystus is

Leiocassis: Ancient Greek, means "with smooth helmet".

Barbus fasciatus, the Melon barb

In the south of the Indian subcontinent the age-old Deccan plateau is
situated, which was formed already in times when India was still a part of
Africa. Many rivers and brooks run from there directly in the Indian Ocean.
In many of them endemic varieties/subspecies/species of freshwater fish have
developed due to the geografic isolation. This is especially true for the
barbs and loaches. Most of these endemic forms have never been researched by
scientists. 

A typical member of the freshwater fish community of that region is Barbus
or Puntius fasciatus, the Melon barb. For this species all the things
mentioned above are applicable to. Many colour varieties exist in the
different rivers. Most wanted in the hobby are the red varieties, but there
are also yellow and orange ones.

202%202010/369523-barbus%20fasciatus%20white%20band.jpg> 

Currently we have very beautiful wild collected ones in stock, which have a
brilliant red basic coloration. The males litterally seem to glow from
inside. The Melon barb becomes around 8 cm long and is completely peaceful.
Like all barbs it nibbles on soft parts of plants when it is not fed
properly by the aquarist with vegetables. They are undemanding regarding
water chemistry and should be kept at temperature of around 26°C. A kind of
"winter rest period" at lower temperatures (18 - 22°C for 6-8 weeks) is very
positive for the fish´s health, but this is not indispensable.

fasciatus: Latin, means "striped".

Corydoras sp. C40 

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/2010/kw%
202%202010/245673-C40%20mann.jpg> 

This pretty cory comes from the Brazilian state of Rondonia. It is not
possible to distinguish the fish from Corydoras griseus externally. However,
Corydoras griseus comes from Guyana and between the collecting sites of both
species are serveral thoundands of kilometers. So it was decided to wait
until a scientist has researched the identity of both fish and to give the
fish from Rondonia the provisional name C40. So it is possible to avoid
unwanted crossings in the aquarium.

202%202010/245673-C40%20frau.jpg> 

Although Corydoras sp.C40 is not really colorful, it is a very attractive
species which developes a nice "fishbone-pattern" on the flanks. It is an
absolutely peaceful and undemanding species. As the fish belong to the
classical roundnoses they like to be in company of their kind and should be
kept in small schools (6 or more individuals).

202%202010/245673-C40%20gruppe.jpg> 

Lexicon: Corydoras: from ancient greek, means "with helmet and spear". This
refers to the strong armor and fin spines. griseus: Latin, means "grey".
