From time to time we receive a very flat-bodied Ancistrus from the Orinoco drainage in Colombia and Venezuela under the name of A. ranunculus/L 34. However, this species does not exist there, A. ranunculus is only known from the Amazon tributaries Xingu and Tocantins/Araguaia; the Orinoco species is Ancistrus macrophthalmus, which has received the LDA […]
This week we received a good number of the interesting frogmouth catfishes of the species Chaca bankanensis from Sumatra. In contrast to the rather reddish animals we could import earlier (https://www.aquariumglaser.de/en/fish-archives/chaca_bankanensis_en/), this time they are rather brown-black colored, probably an origin-related color characteristic. Very interesting is that some animals have striking white colored eyes. At […]
This beautiful Corydoras belongs to a scientifically undescribed species. It originates from the upper Rio Negro in Brazil. Because of the bright orange neck spot it is usually misidentified as Corydoras burgessi, which also comes from this region, especially as C. burgessi has a very variable pattern and there are also spotted colour variants of […]
Just as L-numbers are assigned for undetermined loricariids, C- and CW-numbers are assigned for undetermined Corydoras. One of the first species to receive such a number was Corydoras parallelus, which was assigned the number C2 in 1993. In the same year Burgess described it as C. parallelus. The species originates from the upper Rio Negro […]
There are two species of catfish in South America that look like siblings: Leiarus marmoratus (called “Achara” by the natives) and Leiarius (formerly: Perrunichthys) perruno. Both species attain a length of about 60 cm, have the very same leopard pattern and the long, ringed whiskers. But there does exist an easily recognizable difference: Leiarius marmoratus […]
For the first time we could (recognized) import this dolphin catfish from Peru. The small species (the biggest scientifically known animal had a standard-length – therefore without tail fin – of barely 8,5 cm) occurs in the area of the upper Amazon, where the river is still called Solimoes. Tympanopleura cryptica was described scientifically only […]
Unfortunately this interesting catfish from Venezuela is offered only very rarely. It lives in the tributaries of the middle Orinoco. With a maximum length of 10 cm (only very rarely some specimens reach this size, the normal size is 6-7 cm) the species remains relatively small. Pseudolithoxus species are all quite flat, but P. kelsorum […]
The armored catfishes of the closer relationship around Corydoras elegans belong to the most interesting species of this huge genus. They do not live as strongly bottom-bound as most other armored catfishes and are very nicely colored. Males and females differ relatively clearly in coloration. However, it is not easy to provide a color description […]
Squeakers or upside-down catfishes are a fish family occurring exclusively in Africa. The best known genus is Synodontis, which comprises over 130 species. Closely related to this genus is the genus Microsynodontis. The genus name means “small Synodontis” and is program, because these fish already become sexually mature with 3-4 cm of length, are thus […]
