  • 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. […]

    We received extremely beautiful German bred Black Diamonds. Moreover the fish are sorted by pair!

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 […]

  • 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. […]

    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.

    Potamotrygon cf. schroederi

    6. July 2007

    Recently we could import this strongly at Potamotrygon schroederi reminding ray from Colombia. Similar as P. schroederi it possesses a strong tail and bright points, which resemble a flower pattern. The Orinoco and its tributaries are the origin of the so called Flower – Rays. Their maximum size might be approximately 60 – 70 cm, […]
