  • Potamotrygon wallacei

    29. March 2018

    This freshwater stingray lives endemically in the Rio Negro system in Brazil and is or was the most often imported species of Potamotrygon from Brazil at all. However until recently they fish were wrongly identified as P. histrix, a different species that is not kept in aquaria at all and occurs in southern South America. […]

  • Potamotrygon leopoldi Black Diamond German Bred

    We received extremely beautiful German bred Black Diamonds. Moreover the fish are sorted by pair! The Black Diamond is a variety of Potamotrygon leopoldi that originates from the upper Rio Xingu in Brazil. These splendid stingrays attain a maximum size of about 40-60 cm disc width. One should never forget that the poison of these […]

  • Potamotrygon

    5. May 2014

    Funny enough: some of the most popular species of a group in the trade are often totally unknown to science! This is for example the case in P. “hystrix” from the Rio Negro basin in Brazil. This species stays comparatively small – around 30 cm disc width – and is thus quite popular in the […]

  • Beautiful P14/Itaituba, bred specimens

    24. March 2014

    The taxonomy of the black river stingrays is very confusing. Three scientifically described species do exist: Potamotrygon henlei (described from the Rio Tocantins), P. leopoldi (described from the Rio Xingu), and P. garrapa (described from the Rio Branco). In P. henlei several varieties exist that possibly represent different, separate species. All specimens from the Rio […]

    We received German bred specimens of this comparatively small (about 35 cm disc width) freshwater stingray. The species is restricted – as far as known – to the Rio Tocantins in Brazil. For our customers: the animals have code 282012 on our stocklist. Please note that we exclusively supply the wholesale trade. Available in very […]

  • Potamotrygon sp.

    25. January 2011

    We have received two beautiful stingrays from Peru which were collected in the Rio Ucuyali. Both specimens have a disc width of about 15-20 cm and are males. According to the grade of development of their sexual organs the species grows to a much bigger size. The fish do not fit any scientific description published […]

  • Potamotrygon cf. falkneri

    18. March 2009

    Currently we have a great selection of wonderful river stingrays from Paraguay belonging to that species in stock. As in all river stingray species, each individual has its own colour pattern, which differs clearly from all other congeneers. This is one of the reasons why species can only be distinguished with great difficulties in Potamotrygon. […]

  • Great variety of freshwater stingrays available at Aquarium Glaser

    23. February 2009

    The export stop of freshwater stingrays (Potamotrygon) has ended and so the very much sought after black species (P. henlei and P. leopoldi) are regulary available now again. Beside these Brazilian black rays we have astonishing Flower rays (P. schroederi) from Colombia and Venezuela, fantastic „King Marble”and Fire Spot” from Colombia (called P. motoro in […]

  • Potamotrygon sp. „Mantilla ray“

    Potamotrygon sp. „Mantilla ray“

    6. July 2007

    This freshwater ray originates from Paraguay. The multitude of forms and colours never stops to amazes one. In the past the scientific description of freshwater rays used to be done according drawings without any conserved specimens from natural museum history collections. The classifications of live animals by such limited descriptions are almost impossible to make.(Photo: […]

  • Potamotrygon sp. „Maracaibo Ghost“

    Potamotrygon sp. „Maracaibo Ghost“

    6. July 2007

    The ghost of Maracaibo. So a novel by Gabriel Garcia Marquez could be named, here however it is about a newly imported ray. Few specimen of these with Potamotrygon yepezi related species reached us last week from Venezuela. There they inhabit muddy bank sections in shallow, clouded waters in the supplies of lake Maracaibo. They […]
