Subject: Guyanese severum
Content-Type: text/plain; charset=ISO-8859-1
According fishbase.org & Eschmeyer's Catalog we have four Heros species
with such distribution:
Heros severus from Orinoco River basin, in the upper Orinoco River drainage
in Colombia and Venezuela; Amazon River basin, in the upper Negro River
Heros efasciatus (common name - Peruvian turquoise severum) from Rio
Amazonas basin, in tributaries of the Rio Ucayali and Rio Amazonas in Peru,
and Rio Solimoes-Amazonas in Brazil;
Heros notatus from Rio Amazonas basin, in the Rio Negro, Brazil;
Heros spurius from Amazon River basin, in the Guaporé River drainage;
... and no one from Guyana.
But the most wild severums in aquariums are typically imported from Guyana.
So what species the Guyanese severum is ?
Thanks in advance,
