Vermehrung von Corydoras pantanalensis geglückt

Die folgenden Ausführungen wurden von unserem Mitglied Regina SPOTTI vor einiger Zeit online in einer Gruppe von Panzerwelsfreunden zur Verfügung gestellt. Da dort aber alles nur auf Englisch lesbar und der Zugang beschränkt ist, dachten wir uns, dieser Ort sei ideal für eine deutsche Version. Continue reading

Hypancistrus cf. margaritatus “L 136c”

Neither the species nor the particularly attractive form treated here, which became known in aquaristics with the addition “c”, is something really new. In the last two to three years, however, there have been some changes in selection and linebreeding, which is why a particularly beautiful specimen is presented here. Continue reading

Thayeria obliqua

In contrast to its close relative Thayeria boehlkei, Thayeria obliqua is only rarely found in trade. The third species of the genus Thayeria ifati is even rarer. I have not seen it myself yet, which might be due to its endemism in the rivers of Maroni and Approuague in French Guyana, from where no exports can be realized. The fourth, recently described species Thayeria tapajonica MOREIRA & LIMA, 2017 originating from Rio Tapajós in Brazil is not in trade either. Continue reading

Ein wissenschaftlich neuer Trugdornwels: Spinipterus moijiri

In der Familie der Trugdornwelse (Auchenepteridae) wurde im November 2019 eine neue Art beschrieben, die in der Aquaristik bereits länger bekannt ist: Der „Otorongo-Trugdornwels“ heißt jetzt Spinipterus moijiri. Continue reading

Big, rare and predatory: Piranhas at Wharf Aquatics

In September `19 the Preston Aquarist Society invited me over for their yearly Convention, an event I was really looking forward to and which I had attended in 2017 for the first time. Continue reading

Again and again: “L 56”

Constantly one encounters the designation “L 56” in stock lists, in shops as well as in many many lists of aquarists. This refers to Parancistrus aurantiacusthe “Golden Broad-headed Sucker Catfish”, but this species does not have an L-number and should never have been given one, because it was scientifically described by CASTELNAU in 1855 and therefore does not fall under the fish numbers were given to: a species that is indeterminable at the time of number assignment and therefore “deserves” an L-number.

Eine wahre Pracht: CW158

Aus einem Zufluss des brasilianischen Rio Negro konnte Pier Aquatics (Wigan, England) zu Beginn des Jahres einen neuen Corydoras importieren, der Anfang April eine neue CW-Nummer bekommen hat: CW158. Bis dahin wurde dieser ausgesprochen attraktive Panzerwels als Corydoras sp. “parallelus II” bezeichnet, in Anlehnung an die Ähnlichkeit der Flankenzeichnung. Continue reading
