Yesterday we received for the first time ever this beautiful new Cory. Its fantastic
black-and-white-coloration will make it without any doubts to one of the favorite
species for Corydoras enthusiasts. Specialzed aquarists already know the fish under
the code CW49. More about this new entry next week!

Pinirampus sp. "Paraguay" 

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/2010/kw%2014%2020

The catfish family Pimelodidae is restricted to South America. It is a quite diverse
family. Although only about 90 species are known they could hardly be more
contrasting. The smallest species (a still undescribed one from the Amazon river)
becomes only 2.5 cm long, the largest (Brachyplatystoma filamentosum) becomes 2
metres long. Most species, however, reach 20 - 80 cm in length.

Determination of the species is not easy, because many of them look very different in
juvenile coloration compared with the adult coloration. Moreover, also the
proportions change drastically during the individual growth.

The species we currently imported from Argentina and Paraguay fits best to the genus
Pinirampus. Especially the very long adipose fin which orginates immediately behind
the dorsal fin reminds one of Pinirampus (other genera with a comparably adipose fin
are Calophysus, Exallodontus, Pimelodina and Propimelodus). The genus Pinirampus
contains only one accepted species, eg P. pirinampu, which has a very wide
distribution in South America. However, it is not reported so far from Argentina and
Paraguay. The fish were sent under the name of Megalonema platanum which has a much
deeper body and a different shape of the adipose fin. Due to these findings we name
the fish in question Pinirampus sp. "Paraguay".

The nice colored species seems to stay relatively small. Our largest ones are around
20 cm long. Among each other they are very peaceful. They have a very interesting way
of resting: they "sit" on their large ventral fins and the caudal. So they have an
angle (compared to the horizontal bottom) of about 30°. When one takes a look on the
very large caudal fin it seems plausible that the catfish lurk in this postion for
small fish, which they prey on by a "catapult start". In the aquarium the catfish
feed on any frozen food of the right size.

For our customers: the fish have code 280253 on our stocklist. Please note that we
exclusively supply to the wholesale trade.

Lexicon: Pinirampus: anagram to the specific name "pirinampu". pirinampu: not
explained in the original description, probably from an indigenous name for the fish.

Enneacanthus obesus 

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/2010/kw%2014%2020

The Banded Sunfish (Enneacanthus obesus) is a coldwater fish and a real oldtimer
among aquarium fish. Aquarists used to name the up to 7.5 cm long fish "working class
discus", due to its brillant colours and the nice behaviour. However, it was never as
expensive as the discus.

Banded Sunfish occur in nature along the southeastern coastal region of the US. Here
they live in ponds and slow moving rivers with clear water and a dense vegetation. In
the aquarium they are not undemanding. They need clean, clear and preferably soft and
slightly acidic water. Moreover they are said to be very anxious and can die when
shocked.

Neverless it is not a big problem to fulfill these demands and a tank with Banded
Sunfish belongs to the most beautiful looks one can have in the whole aquarium hobby.
Like all sunfish, the Banded Sunfish usually refuses flake food, it is better to feed
them on frozen and live food

The term "coldwater fish" is often misunderstood. In this case it does not mean that
the tank for sunfish has to be cooled in living rooms. These species have no problem
with temperatures as high as 26°C for some time. However, they need a cool period
during winter at 4-10°C, otherwise they will not breed. In Central Europe this
species will not survive extreme winters in the garden pond, so it is better to bring
them in a cool cellar room from December to March.

For our customers: the fish has code 415203 on our stocklist. Please note that we
exclusively supply the wholesale trade.

Lexicon: Enneacanthus: ancient Greek, means "with nine spines". This refers to the
structure of the dorsal fin. obesus: Latin, means "thick".

Parasphaerichthys lineatus

Once more we have the smallest anabatoid fish of the world in stock:
Parasphaerichthys ocellatus, the mini chocolate gorami. This tiny species hardly
reaches 2 cm in length. In contrast to all other chocolate gouramis this is a
bubblenester builder (all others are mouthbrooders) and should be kept and bred in
harder, slightly alcalic water (all other chocolate gouramis need soft, acidic
water).

The sexes are hardly to tell apart, except during the breeding season. Then the male
changes its coloration drastically and becomes bright orange-yellow.

Tankmates (which, however, must be also small and peaceful, for example Microdevario
nana, Microrasbora spp or Celestichthys spp. are suitable) will not be harmed. This
is also true for conspecifics. Despite the small size of the fish it is recommended
to keep them in larger tanks and in groups. Here all their fascinating behaviour can
be observed.

For our customers: the fish have code  441212 on our stocklist.Please note that we
exclusively supply the wholesale trade.

Lexicon: Parasphaerichthys: ancient Greek, means "similar to Sphaerichthys".
Sphaerichthys is another genus of fish. lineatus: Latin, means "lined", referring to
the coloration.
