Astroblepus from Peru imported!

The L-numbers or Loricariidae belong to the most popular species of catfish from
South America. But even very experienced aquarists will hardly ever had the
opportunity to see alive a specimen of the genus Astroblepus, although the family
Astroblepidae, which includes the single genus Astroblepus, is the closest relative
of the loricariids. Astroblepids are distinguished from loricariids by the naked
body, which is covered by bony plates in loricariids. So we are very proud that we
have been able to import two species of Astroblepus now for the first time ever,
although in very small numbers.

There are more than 50 species in Astroblepus and no scientific revision has been
done for over 100 years. So a determination of our species would have been virtually
impossible without the knowledge of the origin of the fish (thanks Carlos!). But we
were informed that our fish had been collected in the upper Rio Ucayali region, which
reduced the number of possible species to 6. Although such a determination cannot be
done without leaving some doubts our fish are at least very similar to the described
species Astroblepus mancoi and A. taczanowskii.

The most attractive species is Astroblepus mancoi with a variable tiger pattern,
whereas A. taczanowskii is more or less uniformly orange-brown with a fine marble
pattern. Both species become around 8 cm long.

11/208792-astroblepus-taczanowskii.jpg>
All species of Astroblepus feed on Aufwuchs. The structure of their mouth and teeth
reminds one strongly in loricariids. Astroblepus are adopted perfectly to strong
current. They do not have only a suckermouth, but also a moveable adhesive apparatus
on the belly. Both specializations allow the fish to climb even over the strongest
rapids existing. On the upper edge of the opercula is a small aperture that allows
the fish to breath althout the mouth is sucked to the ground.

11/208792-astroblepus-taczanowskii-maul.jpg>
These fascinating catfish should be kept under cool conditions (18-22°C) and a pump
for a strong current should be installed in the tank. Despite this keeping
Astroblepus can be compared with keeping Ancistrus species. Our specimens have
proofed so far to be very peaceful against each other.
For our customers: Astroblepus mancoi has code 208783, A. taczanowskii 208792 on our
stocklist. Please note that we exclusively supply the wholesale trade.
Lexicon: Astroblepus: from ancient Greek, means "stargazer". Mancoi: dedication name
"for the Inca Ayar Manco, colonizer of Cuzco, the "Moses of the Peruvian Indians",
who, about 1100 A.D. led the exodus from Tampu-tocco." (Eigenmann & Allen, 1942).
taczanowskii: dedication name for the former curator of the Warsaw museum.
Suggestion of common names: A. mancoi: Tiger stargazer catfish; A. taczanowskii:
Orange stargazer catfish.

Pterobunocephalus depressus
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/2011/kw%2030%2020
11/212922-pterobunocephalus-depressus.jpg>
This is by far the most attractive species of all banjo cats - and the rarest. We
recently received the fish for the first time from Peru. It is also one of the most
variably coloured species of banjo cat. Most specimens have a sharp black-and-white
contrasting pattern, being white anterior and black posterior. But there are also
variations, some specimens are almost completely black, others brownish.

11/212922-pterobunocephalus-depressus-trio1.jpg>
Maximum length of Pterobunocephlaus depressus is around 9 cm. Like all banjo cats the
species is absolutely peaceful against any tankmate. Fine sand that allows the fish
to borrow themselves is recommended, but not absolutely necessary. Banjo cats are
strictly night active fish, so one must feed - at least during acclimatisation - the
fish after the light has been switched off. The fish feed readily on any usual type
of live, frozen or dried food.

For our customers: the fish have code 212922 on our stocklist. Please note that we

Lexicon: Pterobunocephalus: from ancient Greek, means "Bunocephalus with a fin",
referring to the comparatively long anal fin; Bunocephalus is another genus of banjo
cat. depressus: Latin, means "flattened".
Suggestion of a common name: Domino banjo cat
