Aquaristik Fachmagazin October/November 2016 – “Catfish Press Review”

Hello catfish freaks,

today I want to introduce you in two articles from the current issue of Aquaristik Fachmagazin

Daniel Konn-Vetterlein “Worm-line Hypancistrus from Rio Xingu – first time examined” (“Wurmlinien-Hypancistrus aus dem Rio Xingu – erstmals genau untersucht”)

For a long time it has been assumed that there are more closely related relationships between many Hypancistrus-forms from the Rio Xingú. Especially Hypancistrus sp. “L 236” and Hypancistrus sp. “L 173” always caused discussions.

Cardoso et. al. (Cardoso et. al. “Integrated Cytogenetic and Mitochondrial DNA Analyses Indicate That Two Different Phenotypes of Hypancistrus (L066 and L333) Belong to the Same Species”) examined the DNA of Hypancistrus sp. “L 66” and Hypancistrus sp. “L 333”. The investigated animals showed no differences on the morphological level in the examined 21st chromosome pair. On this basis, however, they can distinguish from Hypancistrus zebra (L 46).

Ingo Seidel “Tetranematichthys quadrifilis once again imported” (“Tetranematichthys quadrifilis mal wieder importiert”)

Tetranematichthys are driftwood catfishes, which are closely related to dolphin catfishes (Ageneiosus). Due to their appearance, they are also referred as leaf dolphin catfish. The import of Tetranematichthys quadrifilis was random. (It was ordered differently.)
Tetranematichthys are active at night. They eat live food and frozen food. Also they can eat small fishes.
