From the Guyana states (French Guiana, Guyana and Surinam) there are for various reasons hardly any commercial ornamental fish exports. The ornamental fish originating there, e.g. the glow-light tetra, are therefore practically exclusively traded as bred specimens. This is also true for Ancistrus leucostictus, which was brought back from a tributary of the Mazaruni River […]
From Peru we have received extremely pretty knife fish of the species Steatogenys elegans. The genus Steatogenys comprises three species, which are all zebra-like striped. With a total length of approximately 20 cm, they remain comparatively small, only S. ocellatus clearly becomes bigger with 30 cm. The three species are very similar in color. One […]
The magnificent licorice gouramis (Parosphromenus) are among the most threatened fish species on earth. This is due to the extensive destruction of the environment in their habitats. Most of the currently 20 scientifically described species have only been discovered in the last 40 years thanks to aquarium science, as the licorice gouramis differ mainly in […]
For the first time we received this splendid snakehead in the year 2011. It obviously represents a species unknown to science so far. I reminds one strongly to the far spread and variety rich species C. gachua, but the “Fireback” is much bigger, reaching 15 -20 cm (some sources give even 25 cm), it lacks […]
Some aquarium fish are more of a pet than just an observation object. They grow larger than usual and communicate with their keeper. It is often not clear who is observing whom more intensively: the vertebrate in front of the aquarium or the one behind it. Datnioides quadrifasciatus clearly belongs to this category of fish. […]
The Bolivian dwarf cichlid Apistogramma rubrolineata is one of the true rarities in the trade. The species was only discovered in 2001 and scientifically described in 2002. The scientific name of the species refers to the seven brown-red longitudinal stripes that this species has. However, they are to be seen in full expression only in […]
Breeding marbled swordtails with red basic colour is a challenge. With the “Tiger”, which we can offer for the first time, this goal has succeeded. In every “tiger” the body spotting is individually different. So far that type of swordtails were offered almost exclusively with whitish body-basic-coloring (then one calls them Marble). Many of the […]
Benitochromis are closely related to the Pelvicachromis species and can be compared regarding the aquarium biology quite good with these peaceful and colorful cichlids. In contrast to Pelvicachromis, which are cave brooders, Benitochromis are biparental, ovophilous mouthbrooders. This means that both parents take care for eggs and fry; eggs and fry are given from parent […]
The high number of varierties of Corydoras in the upper Rio Negro is very confusing and even Corydoras experts in some cases have great difficulty in addressing the very similar species. A controversial species from the beginning is Corydoras crypticus, which was described together with C. amandajanea in 1995. The main difference between C. crypticus […]
One of the most coveted Corydoras is the saddle-nosed Corydoras serratus from the upper Rio Negro area in Brazil. Because the saddle-nosed Corydoras are rather loners in contrast to the long- and round-nosed Corydoras, they cannot be collected in larger numbers. This and the fact that these fish were sometimes paid incredible prices in Japan […]
