From the Rio Nanay in Peru originates a species-flock of very similar looking corys. They are distinguished externally basically by the shape of the head and the snout. All of them are very beautiful and suited very well for the aquarium. All have an impressive dark mask over the eye and clear fins. The body […]
This is a very unusual species of tetra. For sure the placement in the genus Hasemania is only tentatively and needs further investigations, as is explicitly pointed out already by the describers (Bertaco and Malabarba, 2007). It was the combination of lacking adipose fin (very unusual in tetras) and certain features of the dentation that […]
The systematics of the wolf tetras from Africa remain unsatisfying. According to the most recent literature there do appear two species in Nigeria, namely Hydrocynus forskahlii and H. vittatus. Both are very similar to each other and at times they were regarded to be mere synonyms. However, currently they are (again) treated as valid species. […]
This species of cichlid from Lake Tanganyika lives in two different worlds. The fish attains a maximum length of about 20 cm; however, in the wild hardly ever specimens larger than 10-12 cm can be found. On the one hand this fish is a typical inhabitant of sandy areas. Here it feeds on small invertebrates. […]
Currently we can offer exclusively some top-rarities among the tetra family, all German bred. One of them is Hyphessobrycon piranga, which was introduced in the hobby by Peter and Martin Hoffmann in the German magazine Datz (issue 11/2017) under the unusual name of „Hyphessobrycon sp. non-red devil“. Despite the fact that the new tetra has […]
Among the small species of cichlid from Lake Tanganyika Neolamprologus cylindricus is one of the prettiest. The very obvious ringed pattern makes it unmistakable. In respect of behaviour N. cylindricus is best comparable with the species of the genus Julidochromis. Like these N. cylindricus form fixed pairs (in large aquaria a male may pair with […]
It was back in the 1980ies that a brick-red sport of whiptail catfish appeared in the former GDR. The real origin of the fish stays a mystery, but it was possible to cross it with Hemiloricaria (formerly Rineloricaria) lanceolata. The strains that exist nowadays are most probably all hybrids. The initial red whiptail catfish belonged […]
Among the most beautiful anabantoids or labyrinth fish from Africa is Ctenopoma acutirostre, the Leopard bushfish. It can become 15-20 cm long. Its natural habitat is the Congo. It is collected there for the ornamental fish trade in the Stanley Pool region. Here the fish live under the swimming meadows of the water hyacinth (Eichhornia […]
This charming free swimming dwarf loach originates from Vietnam. It attains a maximum length of about 3.5 cm. For quite a long time it was placed in the genus Yunnanilus, but currently mot scientists see them in the monotypical (this means the genus contains only one species) genus Micronemacheilus. These fish are totally peaceful and […]
Currently we can offer several species of the livebearing snails of the genus Brotia from Thailand. These snails are no hermaphrodites like many other snails, but the sexes cannot be told apart from external features. However, Brotia will never become a plague like many other snails do. They feed on algae and other Aufwuchs. Water […]
