More Freshwater Fish from Guyana

These are the other two stamps from a 2005 set showing freshwater fish that I used on a cover from Guyana last year. On the left is a red belly piranha and on the right is a velvet cichlid or oscar.

Freshwater Fish from Guyana

From the philatelic bureau in Georgetown, Guyana. The stamps are from a 2005 set showing freshwater fishes that live in the rivers and streams of Guyana. At least I think they live there. Pretty sure they do. On the left is a freshwater stingray and on the right, some splash tetras.
