A new, wonderful Congo Tetra!19.12.2014

We received in our current import from the Congo a beautiful species of CongoTetra under the name of "Phenacogrammus sp. Lukeni River". As the correct determination was impossible at first (the systematics of this group of tetra are quite complicated) we adopted that name for our stocklist. In the meantime we are quite sure that our fish belong to the species Alestopetersius hilgendorfi.

May this be as it is: the fish are really breathtaking beautiful! When we caught them to transfer the animals to the photo-tank they looked much deeper red than later. The solution of that enigma can be found in the magnification of one of the pictures. Here we see that all over the body small red cells are scattered, looking a bit like spread ink. These color-cells can be widened or contracted by the fish, depending on its mood. Obviously the lightning of the photo-tank was a bit too strong for the fish, so they contracted the color cells and looked less red.

These Congo Tetras can obtain a maximum length of 6-7 cm. They should be kept by experienced keepers only, as they need very clean, bacteria-poor water.

For our customers: the fish have code 159004 on our stocklist. Please note that we exclusively supply the wholesale trade.

A new Erythrinus!17.12.2014

We received for the first time ever a species of Erythrinus from Paraguay which we have never seen before: neither alive nor on pictures. The genus Erythrinus is in urgent need of revision. Currently only two species are recognized as valid. The one is spread almost over the whole of South America: Erythrinus erythrinus. The other one is known so far only from Bahia in Brazil: E. kessleri. However, no pictures are known to exist that show for sure E. kessleri. The scientific description of Steindacher (1877) based on the unique shape of a band of teeth in the palate; no external features are known to distinguish the species otherwise from E. erythrinus.

So we name this fish provisionally Erythrinus sp. Paraguay. The vertical bands in the hind half of the body are very characteristic for the species as well as the dark horizontal stripe on the back of the fish. They can be seen best in smaller individuals (8-10 cm). In our largest fish (12-14 cm, they seem to be fully grown) a broad dark horizontal band develops in the front half of the body. Then the fish look at the first glimpse very similar to Hoplerythrinus unifasciatus, which we obtained also from Paraguay. Leaving anatomical details aside, Hoplerythrinus can be best recognized by the dark stripes running from the eye backwards, whereas the also very characteristic dark horizontal band can fade when the fish is under stress. However, the swimming behaviour of Hoplerythrinus and Erythrinus is completely different. The former is found most of the time in open water, while Erythrinus prefers to sit on the bottom or in dense vegetation.

We could hardly find any sexual dimorphism in our new Eryrthrinus. Usually males of Erythrinus can be easily recognized by the much larger dorsal fin. However, we feel that the males in our new fish have a rather golden opercles (greenish-silvery in females). Moreover the head of the putatively females is more rounded.

Against conspecifics, Erythrinus are really aggressive. So don´t be fooled by the pictures. Such a harmony will hardly ever be seen when the fish are settled. In a long time sight one should keep each fish solitary. Erythrinus are obligatory predators and should be fed with fish.

Peckoltia sp. Alto Nhamunda17.12.2014

We are glad to be able to present to you another jewel by the end of the week again. We could import last year already a new species of Peckoltia from the upper Nhamunda River in Brazil, which is also famous for its pretty discus. This first importation contained only fully grown specimens (see

This time we received subadults of about 6-8 cm length. And these are really breathtaking beautiful!

We can offer only very rarely wild collected fishes from the USA. But currently we have some species of minnow in stock, among them the very pretty Chrosomus erythrogaster. These fish do not need a heater, but feel also very comfortable at temperatures over 24°C. Maximum size for that species is 10-12 cm, currently the fish are 5-7 cm long.

Congo-importation arrived!10.12.2014

Once more we were able to organize a wonderful, large importation from the Congo. Our proofed supplier sent us among others beautiful butterfly barbs (Barbus hulstaerti,, large Upside-Down-Cats (Synodontis nigriventris,, also the "Zebra-nigriventris" (, gorgeous Orange Bushfish (Microctenopoma ansorgii,,, healthy Hydrocynus goliath (, the beautiful and rare Congo-Barb (Clypeobarbus congicus,, banded bushfish (Microctenopoma fasciolatum,, and so on, and so on…

One of the most beautiful fish of the World, the six-striped Distichodus (Distichodus sexfasciatus) is also represented by a good number of specimens. We have no doubts that this species would be among the most wanted aquarium fish at all, were there not some characters that make the animals suitable only for the very long-suffering and extremly patient hobbyist: they grow (even in smaller tanks) to a length of more than 30 cm, are extremely quarrelsome and will - for sure! - eat any plant in the aquarium.

Usually this species has six stripes on the flanks. In our current shipment are also several specimens with other numbers of bars, most often seven. But do not think that these fish would represent other species; most often seven bars occur only on one side of the body while the other one has a regular number of stripes.


Seven is a lucky number: in any case it brought luck for our Congo importation, for all fish are healthy, stable and feel very well in their new environment!

For our customers: D. sexfasciatus has code 128001 (3-5 cm) and 128002 (5-7 cm) on our stocklist. Please note that we exclusively supply the wholesale trade.

Bagrus filamentosus04.12.2014

The African genus Bagrus contains large, predatory catfish. The maximum size of the different species is between 30 cm and more than one meter! Sadly the determination of the species is rather difficult, because most of the 11 species that are regarded as valid currently have been described before WW2. A modern revision does not exist.

Bagrus filamentosus is an exciting exception of this rule. The all in all comparatively slender species belongs to the smaller members of the genus. Against conspecifics and other fish Bagrus are usually peaceful, but one should never underestimate the size of the mouth. Every fish that fits that mouth will be eaten!

Our recent shipment of Bagrus filamentosus contains as bycatch another species of Bagrus, possibly Bagrus docmak. This species is much plumper and has a shorter head. One must estimate that these babies will grow to the size of real foodfish. So they should be kept in real large aquaria only.

For our customers: the fish have code 100554 on our stocklist. Please note that we exclusively supply the wholesale trade.

Synodontis clarias04.12.2014

This week we want to focus on unusual species of catfish from Nigeria. Today: Synodontis clarias. This is the first species of Synodontis that became known by scientists. The original scientific description dates back to 1758 and was done by Linnaeus. Nevertheless the species is exported only very occasionally for aquaristic purposes. The fish attains a length of more than 30 cm. It has an enormous distibution: the Nile, Chad, Niger, Volta, Gambia and Senegal. S. clarias is a food fish in all countries it occurs.

Juveniles, like the 6-8 cm long specimens we were able to import now, look very different to adults in respect of coloration. Adults have a slate-coloured body and a red caudal fin.

For our customers: the fish have code 174803 on our stocklist. Please note that we exclusively supply the wholesale trade.
