Caros colegas,

 

Após uma semana de ausência, estou de volta com este número da " newsletter " que
tinha ido parar à pasta do " spam ".

Como grande apreciador e defensor das populações de Guppy selvagens, este número em
particular é para guardar em arquivo.

Nos próximos dias vou-vos actualizar com o correio que entretanto chegou e juntar-lhe
algumas surpresas.

Um abraço

Miguel Andrade

Panoqolus sp. New Zebra Pleco Jutai

This extremely attractive new suckermouth cat was sent to us from Peru with the name
of a collecting site "Jutai". Currently the fish are around 4-6 cm long. There is no
doubt that they belong to the Panaqolus changae group (LDA 26, L206, L226). A very
astonishing matter in these fish is the fact that despite their small size they seem
to be sexually differentiated already. The presumed males have a whitish basic
colour, narrower bands and an irregular pattern on the caudal fin. The presumed
females have an orange basic colour with regular bands.

Has a dwarfish population been discovered? Panaqolus changae (typical form) reaches a
total size of approx. 12 cm and can be kept quite easily. As in all members of
Panaqolus soft wood forms an essential part of the food.

For our customers: the fish have code 275351 on our stocklist. Please note that we
exclusively supply the wholesale trade.

Lexicon: Panaqolus: diminuative of Panaque. Panaque is another genus of suckermouth
catfish. changae: in memory of Fonchii Fang, who was integrated in the discovery of
the species. She died by accident on the Amazon.

Guppy "Venezuela" Top Sword

Since quite a long time we receive wild guppy types from one of our breeders. These
wild types are much sought for, due to their brilliant colours, their lively temper
and their perfect adaptability to almost any aquarium conditions. Under the name of
guppy "Venezuela" recently wonderful fish in show size with top sword reached us. The
most attractive ones have a black eyespot in the white sword; this feature, however
cannot be found in each specimen, but it  surely can be fixed by selective breeding.

Hyphessobrycon peruvianus

Three species of tetra in northern South America are obviously close relatives to
each other and often confused: Hyphessobrycon loretoensis from Peru, H. metae from
Colombia, and H. peruvianus from Peru. From these, H. loretoensis has been portayed
here quite recently
(http://www.aquariumglaser.de/en/hyphessobrycon-loretoensis_de_1188.html).
 
Now we were able to import the second Peruvian species once more, H. peruvianus, in
wonderful, large specimens. This is the most elongated of the three species mentioned
above. It can be distinguished best from its close relative, H. loretoensis, by the
coloration of the caudal fin. In H. peruvianus the black longitudinal band extends
far in the caudal fin. Above and below it is covered by red spots. The lobes of the
caudal fin are hyaline. In H. loretoensis the black band ends shortly after the
caudal fin origin. The caudal fin is completely red.
 
Regarding the aquarium maintanace there is no great difference between the two
species, both are extremely beautiful fish that fit perfectly for any blackwater
community tank.
 
For our customers: the fish have code 261453 on our stocklist. Please note that we
exclusively supply the wholesale trade. 

Lexicon: Hyphessobrycon: ancient Greek, means "small Brycon". Brycon is another genus
of tetras. peruvianus: means "originating from Peru". loretoensis: after the Loreto
province in Peru. metae: after the Rio Meta.

Otocinclus vestitus "Paraguay" 

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/2010/kw%2027%2020
10/vestitus%20normal-ag.jpg> 

The season for this popular Otocinclus has started now. Otocinclus vestitus has a
very large distribution. It is found in Peru, Bolivia, and Paraguay. The species can
be easily identified by the typical pattern in the caudal fin.

Among the O. vestitus we received this week from Paraguay was one very unusual
xanthoristic specimen. It is a very rare occasion that such a conspicious animal
survives in the wild and grows to adult size!

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/2010/kw%2027%2020
10/vestitus%20lutino-ag.jpg> 

Keeping and breeding O. vestitus is very easy; it is a typical beginner´s species.
Especially lovers of well planted aquaria enjoy Otociclus vestitus very much, as it
is a perfect algae eaters that feeds the algae from the top of the leaves without
hurting them at all. For breeding a specis-specific tank should be used. Technically
speaking, breeding is very much alkie that of Corydoras species.

For our customers: the fish have code 273604 (old trade name: O. arnoldi) on our
stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Otocinclus; vestitus: Latin, means "dressed". Xanthorism: a mutation, in
which the cells with yellow pigment increase.
