Ageneiosus lineatus (= sp. III Green Stripe)

12. September 2019

Update: es handelt sich um die Art Ageneiosus lineatus Ribeiro, Rapp Py-Daniel & Walsh 2017

The dolphin catfish were only recently revised and divided into two genera: Ageneiosus and Tympanopleura. Tympanopleura are the smaller species. They are characterized by a circular structure immediately behind the edge of the gill cover, which looks like a tympanum.

Unfortunately, the pretty dolphin catfish imported from Peru from time to time, which is called “Green Stripe”, is not included in the revision and apparently belongs to a scientifically undescribed species. We would classify it also rather in Tympanopleura than in Ageneiosus, especially since it reaches with – as far as known – only 15-20 cm length (usually over 40 cm with Ageneiosus). Among catfish friends this species is also known as sp. III. It has been (and still is) confused with Ageinosus vittatus, but this is a large species with a much rounder head profile and a different pattern.

Flexipenis vittatus

5. July 2019

Once more we are able to offer a beautiful dwarf livebearer that proofed to be a bit problematical in respect of breeding – not keeping! – in a long time sight under traditional aquarium conditions. However, under the open skies of Southeast Asia they breed pretty well.

Flexipenis vittatus is also often placed in Gambusia. Males become 2.5 – 4.5 cm, females 4 – 6 cm long. In nature, this livebearer inhabits Mexico (Atlantic slope).

In contrast to Gambusia Flexipenis has a highly developed courtship display, meanwhile the males present their pretty yellow-black dorsal fins in a very attractive way. It is wise not to keep these fishes year-in year-out at too high water temperatures. In living rooms no extra aquarium heater is necessary. Temperatures may lie between 18 and 26°C.

For our customers: the fish have code 415073 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Gambusia: derived from the Cuban term “Gambusino” for something unimportant. Flexipenis: means “with pliant sexual organ”. vittatus: Latin, means “Striped”.

Suggestion of a common name: Small flag livebearer, Blackline mosquitofish

Telmatochromis vittatus

8. August 2018

Only comparatively rarely Telmatochromis vittatus from Lake Tanganyika can be found in the trade, despite the fact that this dwarf cichlid – it becomes only about 8.5 cm long – is perfectly suited for keeping and breeding in home aquaria. Maybe this is due to the fact that the fish look somewhat similar but not as brillant as Julidochromis species.

Keeping this fish is easy and can be compared with that of the several Lamprologus species. Like these, T. vittatus is a biparental cave brooder which is kept best by pair. Males become larger than females and develop a small hump on the head. The aquarists dedicted to T. vittatus like it very much due to the fact that this fish loves to feed on small snails. This led to the misleading popular name „Striped Snail Telmatochromis“. However, hobbyists think that a snail cichlid is a species that prefers to breed in empty snail shells; T. vittatus does not usually.

Hydrocynus vittatus

16. June 2018

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. The most important distinguishing feature is the black seam in the caudal fin in H. vittatus, which is lacking in H. forskahlii.

Hydrocynus vittatus is, compared with other species of that genus, comparatively small and becomes „only“ about 60 cm long. Of course this fish is nevertheless only suited for owners of really big tanks. Against conspecifics the fish are rather peaceful, so if one has such a big tank and interest in keeping Hydrocynus it is best to try to keep it in groups. Hydrocynus feed exclusively on fish. Specimens that have adopted to the aquarium readily accept frozen fish.
