09. Characoids: tetra relationship (368)

  • Erythrinus erythrinus PERU

    13. September 2019

    According to the current state of science, the predatory tetra species Erythrinus erythrinus is widespread throughout practically all of South America: Argentina, Brazil, Ecuador, Peru, Colombia, Paraguay, Bolivia, French Guiana, Guyana, Suriname, Trinidad and Tobago and Venezuela. However, they look somewhat different everywhere, so that one must assume that in case of a modern revision […]

  • Leporinus friderici

    7. August 2019

    One of the longest known Leporinus species is L. friderici. It was already described in 1794 under the name Salmo friderici. The author, Marcus Eliser Bloch, writes: “This fish is a resident of Surinam’s waters. I received it from the present governor, the Lord of Friderici, along with several other fish. He has an excellent […]

  • Hemigrammus cf. bellottii “Venezuela”

    17. July 2019

    One of the most common tetras from the Amazon and Orinoco is Hemigrammus bellottii. The species is easily recognizable by the golden longitudinal stripe and the red eye; other pattern elements (tail spot, fin coloration etc.) are usually missing. Only a shoulder spot can be present from time to time – depending on the mood. […]

  • Pyrrhulina spilota

    12. July 2019

    The tetras belonging to the genus Pyrrhulina combine the advantages of two basic groups of ornamental fish. The first group are the schooling species that are always visible and swim merely in the open water: tetras and barbs. The second group has a fascinating behaviour and takes care for the brood: the cichlids and the […]

  • Hoplias malabaricus “Venezuela”

    1. July 2019

    We have already mentioned it: currently we have three species of the genus Hoplias from Venezuela in our stock. The common wolf tetra (Hoplias malabaricus) has a huge distribution area, but it is very likely that this “species” proves to be a species complex consisting of several, at least partially undescribed species.  With the “Hoplias […]

  • Hoplias curupira

    28. June 2019

    Right now we have three Hoplias species from Venezuela in our stock. Hoplias curupira belongs to the real rarities and is accordingly sought after among predatory fish fans. With a final length of about 40 cm the stocky species remains relatively small. It belongs within the genus Hoplias to the so-called H.-lacerdae group, which besides […]

  • Moenkhausia simulata

    14. June 2019

    We obtained a somewhat irritating import of a very rare species of tetra last week from Peru. In all probability, it is Moenkhausia simulata; however, our new import differs slightly from the previously known M. simulata in coloration. All other tetra species with a pattern of several horizontal stripes (Astyanax lineatus, A. kullanderi, A. superbus, […]

  • Hyphessobrycon peruvianus

    27. May 2019

    Three species of tetra in northern South America are obviously close relatives to each other and often confused: Hyphessobrycon loretoensis from Peru, H. metae from Colombia, and H. peruvianus, again from Peru. From these, H. loretoensis has been portayed here: http://www.aquariumglaser.de/en/hyphessobrycon-loretoensis_de_1188.html. Currently we were able to import the second Peruvian species once more, H. peruvianus, […]

  • Synaptolaemus latofasciatus

    17. May 2019

    Finally we managed to import again some specimens of this unusual “striped sock” from Venezuela. The species – there is just the one in the genus Synaptolaemus – was long known under the name S. cingulatus, until Britzki et al. discovered that the species described as Leporinus latofasciatus by Steindachner in 1910 was identical with […]
