  • Potamotrygon orbignyi BRED and P. sp. Mantilla PERU

    24. February 2020

    For the first time we can offer a good number of German offspring of the freshwater stingray Potamotrygon orbignyi. Because of the extreme variability in colour this species, which was already scientifically described in 1855, is difficult to determine. The type specimen that Castelnau had at hand came from the Rio Tocantins in Brazil. As […]

  • 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

    9. September 2015

    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 […]

  • Potamotrygon scobina

    5. October 2012

    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 […]

  • stingray-babies

    6. July 2007

    July 2005: During the night from Sunday to Monday it was about time: We got three babies. About five weeks ago we had received a female from Pantanal River and we immediately noticed on arrival that this fish was not alone: It was pregnant. After five weeks now of intensive care, these three babies were […]

  • Dasyatis margarita

    Dasyatis margarita

    6. July 2007

    March 2002: Just today we got from west-africa a few pieces of DASYATIS MARGARITA, the daisy stingray. These are found in brackish & freshwater. The ones we got were caught in pure freshwater. It is for us, Aquarium Glaser, the first time that we got this fish!(Photo F. Schäfer, Text K. Diehl)

  • Himanthura signifer

    Himanthura signifer

    6. July 2007

    The white-rimmed-stingray is surely an untypical member of the stingray family. The tail of the shown stingray which have a disc-size of 20cm, is more than 85cm long!(Photo F. Schäfer, Text K. Diehl)

  • Potamotrygon cf. schroederi

    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, […]

  • Potamotrygon leopoldi

    Potamotrygon leopoldi

    6. July 2007

    The Black- or Eclipse-Ray is an endemic species from the Rio Xingu in Brazil. This is definitely one of the most beloved rays in the aquatic hobby. This ray is relatively easy to maintain. He will adapt fast to his new captive surroundings and will start eating quickly. This species can be housed very well […]

  • Potamotrygon menchacai

    Potamotrygon menchacai

    6. July 2007

    September 2006: From Potamotrygon menchacai, the tiger stingray, we could import a big, very beautifully patterned, female animal with approximately 60 cm in diameter. Tiger-rays can be colored quite differently and particularly can differ in the contrast. Our tiger rays come from Peru, through size and scrutiny, they certainly are among the most impressive “ornamental-fishes.” […]

  • 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 […]

  • Potamotrygon sp. „Pearl“

    6. July 2007

    From one of the most sought – after of the Amazonian stingrays in the hobby, Potamotrygon sp. “pearl” we could offer first European bred offsprings. Pearl rays got their names for the repeating pattern of pearl-like spots within black rings covering its dorsum. Their origin is the Rio Tapajos where it share its biotopes with […]
