L261a - Ancistrinae gen. sp. "Ventuari"

L261a - Ancistrinae gen. sp. "Ventuari"
L261a - Ancistrinae gen. sp. "Ventuari"

This species of fish is among the rarest of all L-numbers. It belongs not only to none of the species described so far, but also cannot be applied to any described genus.

L261 was imported initially from the Orinoco in Venezuela. The individual we were able to import now for sure belongs to the same species.

But due to minor difference in coloration (L261 has tiny white spots on the snout, our fish is lacking them) and the known collecting site

(the Rio Ventuari is a large tributary of the Orinoco in Venezuela) we have decided to place an "a" behind the L-number.

L261a - Ancistrinae gen. sp. "Ventuari"
L261a - Ancistrinae gen. sp. "Ventuari"

Maximum length of the species should be 20-25 cm. The large mouth with the very tiny teeth shows clearly that the species feeds on Aufwuchs?.

Thus keeping L261 should be comparable to that of Ancistrus spp., although the temperature should be slightly higher, as it is found in nature: 26-29°C.

For our customers: the fish has code 26480-L-261A-6 on our stocklist. Please note that we exclusively supply the wholesale trade.

Eigenmannia trilineata

Eigenmannia trilineata
Eigenmannia trilineata

We received wonderful specimens of Eigenmannia from Guyana. They show three black longitudinal stripes on a smokey ground. This fits perfectly

to the pattern described in the species E. trilineata, which is known so far only from the Paraguay-Paraná system (Argentina, Brazil, Paraguay, Uruguay).

May that be as it is: Eigenmannia are fantastic aquarium fish that show an incomparable elegance. Males can reach about 40 cm in length, which is double

 as long as females can become. Females have also a much shorter snout. Breeding of Eigenmannia is possible if a rainy season is imitated. As soon as the

fish are in the right condition, they spawn in the roots of swimming plants.

Knife fishes need well structured tanks with a good number of hiding places. Feeding them is pretty easy, for the fish accept readily any type of live and

frozen food. Many also accept granulates.

For our customers: the fish have code 252905 on our stocklist. Please note that we exclusively supply the wholesale trade.

Rachoviscus crassiceps

Rachoviscus crassiceps

Finally we are able to offer once more this beautiful, but sadly only very occasionally available tetra. However, even now we have only a limited

number of them.

Although the fish is really beautiful - one of the most attractive features is the deep red adipose fin - this is not the main excitement for the keeper of

Rachoviscus crassiceps. Each aquarist should have had at least once in a lifetime the opportunity to observe the fantastic dance the male performs

during displaying, may it be while having a harmless fight with another male or during courtship.

In nature, R. crassiceps inhabits brooks with soft and acidic water in the south of Brazil. This means that they are subtropical fish that need no additional

heater in indoor aquaria with the exception of breeding season. The regular water temperature can lie between 16 and 24°C.
The very peaceful tetras feed on any usual type of fish food.
For our customers: the animal has code 286902 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Rachoviscus: dedication name for Arthur Rachow. crassiceps: composed from a Latin and an ancient Greek word, means "with thick head".

Adontosternarchus clarkae

Adontosternarchus clarkae
Adontosternarchus clarkae

This small (maximum length up to 20 cm) knifefish from Venezuela is only rarely imported and again we were able to obtain only a few specimens. It is a very nice and peaceful species. The genus Adontosternarchus currently comprises four accepted species which can be distinguished best by differences in the head profile in combination with the shape of the mouth.
Like all South American knifefishes, this species is weakly electrical and communicates with conspecifics via electrical impulses. Of course, these impulses are also used for orientation. Knifefishes develop most activity at dawn and so the tank should not be too much illuminated and should contain a good number of hiding places.

The fish feed basically on Tubifex and frozen fishfood. Regarding the water chemistry they seem to be undemanding. However, soft and acid water should be preferred against hard and alcaline water. The water temperature should be a little higher than usual, about 26-28°C will do best.

For our customers: the fish have code 202782 on our stocklist. Please note that we exclusively supply the wholesale trade.

Panaque sp. L418 Shampupa

Panaque sp. L418 Shampupa
Panaque sp. L418 Shampupa

The magnificent Panaque species which belong to the P.-nigrolineatus-complex are much sought for ornamental fishes. All species seem to become around 40 cm long. One of the most spectacular ones originates from Peru and received the L-number 418. Characteristic features of the fish, which is called Shampupa by the exporters, is the broad light band in the caudal fin und the turquoise-green basic coloration.

Shampupa is a very rare fish and available only in very limited numbers. Like all Panaque, it is a specialized feeder that feeds in the wild almost exclusively on dead wood.

So it is absolutely necessary to decorate a Panaque tank with lots of roots. However, the fish take in captivity also a lot of different types of regular fishfood.
For our customers: the fish have code 26480-L-418-5 on our stocklist. Please note that we exclusively supply on the wholesale trade.

Characidae gen. sp. "Yellow Glass" - a new dwarf tetra

Characidae gen. sp. "Yellow Glass" - a new dwarf tetra
Characidae gen. sp. "Yellow Glass" - a new dwarf tetra

For the first time ever we were able to import this charming dwarf tetra from Peru, which cannot be placed in any known genus or species so far. Our largest specimens are about 1.5 cm long. Of course it is possible that our fish represent only juveniles of a larger species, but this thesis seems to be unlikely, as there can already some mating behaviour be observed. During displaying the specimens thought to be males change the colour of the lower lobe of the caudal fin, which becomes black. So the fish reminds one at times somewhat in the Penguin tetra (Thayeria boehlkei).

Keeping the new dwarf tetra proofed so far not very problematic. The charming fish dont like too much current. All in all the new species is a wonderful addition for the nano tank aquarium hobby.

For our customers: the fish has code 215513 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Thayeria: dedication name for N. Thayer, who sponsored an important ichtyological expedition through South America from 1865-1866. bohlkei: dedication name for James E. Böhlke, an american ichthyologist.
