Ageneiosus cf. atronasus

Ageneiosus cf. atronasus
Ageneiosus cf. atronasus

For the first time ever we received now this interesting doplhin catfish from Peru. In contrast to many of its congeneers this species stays relatively small and reaches only 12 cm in total length. Thus it is suitable also for normal sized home aquaria. However, one should always keep in mind that these catfishes are predatory fish and that tankmates must not be too small. Otherwise the dolphin cat is a peaceful species.
During breeding season the males develope very long dorsal spines that are used while mating to fix the female. There is an internal insemination, but most details regarding the natural history of these interesting fishes are still unknown.
For our customers: the fish have code 202902 on our stocklist.Please note that we exclusively supply the wholesale trade.
Lexicon: Ageneiosus: from ancient Greek, means "without a beard"; this refers to the fact hat the barbels are usually hidden and cannot be observed externally. atronasus: Latin, means "with a black nose".
Suggestion of a common name: smut nose dolphin cat

Erythrinus sp. TAHUAYO RIVER

Erythrinus sp. TAHUAYO RIVER
Erythrinus sp. TAHUAYO RIVER

Another recent first importation from Peru: a new species of Erythrinus! It is clearly distinguished from the other two species of Erythrinus known so far from Peru, eg Erythrinus erythrinus (see http://www.aquariumglaser.de/en/erythrinus-erythrinus-_de_1009.html) and E. sp. Madre de Dios (seehttp://www.aquariumglaser.de/en/erythrinus-sp-madre-de-dios_de_1324.html) by the fine, whiteish-blue seam Keeping Erythrinus is quite easy. The fish easily accept deep frozen fish (smelt) as main food item. As the fish have an accessory breathing organ, the water quality is of lesser meaning. Temperature should not raise over 25°C over a longer period, for at least the Peruvian Erythrinus are somewhat sensitive in this respect.
For our customers: the fish have code 253382 on our stocklist. Please note that we exclusively supply the wholesale trade.
Lexicon: Erythrinus: ancient Greek, means about "the reddish".

Tridensimilis brevis

Tridensimilis brevis
Tridensimilis brevis

Currently we received the cute freeswimming dwarf glass cat Tridensimilis brevis from Peru. The fish attains a maximum length of 3 cm. It belongs to the notorious candiru relationship, but is no blood sucker at all. This tiny catfish is that translucent that it is possible to observe the way of the food from the mouth to the vent. T. brevis can be kept problem free with small tetras, but one should better keep no Corydoras - especially C. pygmaeus - along with Tridensimilis. For our customers: the fish has code 298151 on our stocklist. Please note that we exclusively supply the wholesale trade.

Cichla kelberi

Cichla kelberi
Cichla kelberi

For the first time ever we have Cichla kelberi in stock, a species that was only recognized in 2006. The fish is available only in a very limited number. The species is distinguished from its closest relative, C. monoculus, by the presence of light spots in the pelvic fins, the anal fin and the lower lobe of the caudal fin in adults. Cichla kelberi attains a total length of about 30 cm which means that it is one of the smallest members of the genus. For our customers: the fish has code 636333 on our stocklist. Please note that we exclusively supply the wholesale trade.

Barbus rohani

Barbus rohani
Barbus rohani

It was only last year that this beautiful Indian barb has been described scientifically. It originates from the south of India. Presently it is only known from hill streams in the Kanyakumari District, Tamil Nadu. It differs from the other Indian barbs of its closer relationship (eg B. arulius, B. assimilis, B. exclamatio, B. filamentosus, and B. tambraparniei) by the coloration. Especially diagnostic is the shape of the caudal spot, which is teardrop-shaped in B. rohani and circular in B. assimilis and B. filamentosus, the two species that look most similiar to B. rohani. Moreover, the caudal fin of B. rohani has no pattern, whereas in B. assimilis an d B. filamentosus this fin has black markings.
Males and females can be easily distinguished by the shape of the dorsal fin which is filamentous in males. Like all these Indian barbs B. rohani is a wonderful schooling fish for larger aquaria. The species attains a length of around 8-12 cm.
For our customers: the fish has code 370914 on our stocklist. Please note that we exclusively supply the wholesale trade.
Lexicon: Barbus: Latin, means "the bearded". rohani: dedication name for Rohan Pethiyagoda, an ichthyologist that works mainly on the freshwater fishes of Sri Lanka and India.
Suggestion for a common name: Golden Scaled Indian Barb

Crenicichla lugubris "Orinoco"

Crenicichla lugubris "Orinoco"
Crenicichla lugubris "Orinoco"

We received beautiful Crenicichla lugubris from Venezuela in three sizes. It is astonishing how drastically these fishes change their coloration during their onotgenesis. Juveniles that show the typical "French fries pattern" are schooling fish that feel very unsafe when kept alone.Then the fish come in the age of puberty. Now they see congeneers only as competitors and try to bite and kill them whenever they have the opportunity to do that. Finally the fish become sexually mature. Now they form pairs that live most often in peace and harmony over long periods. The elder the fish become, they more beautiful they are. The Orinoco variety of C. lugubris has a high amount of red in the coloration. This population also has characteristically a lot of spots in the face which can lead to confusion with C. lenticulata that lives in the same area. C. lugubris "Orinoco" is one of the largest species of the genus and can attain a length of around 50 cm. So it is an magnificent subject for very large or public aquaria.Lexicon: Crenicichla: Crenicichla: ancient Greek, means "Cichla with a comb"; Cichla is another genus of cichlid. lugubris: Latin, means "the one that wears mournig", this refers to the coloration.

Suggestion of a common name: Giant Orinoco Pike Cichlid
