Guppy Fish

Guppy fish were originally native to the Caribbean and to South America , but now they have been introduced in all the continents except Antarctic. Sometimes this has occurred accidentally, but most often as a means of mosquito control, the hope being that the guppies would eat the mosquito larvae slowing down the spread of malaria. This versatile fish can survive both in Fresh water and sea water even in salinity as high as 150% of that of the sea water.
For this photograph, the fish were placed in a transparent polythene bag and behind the bag a black board with a large opening was placed. Light was placed behind the backdrop, the idea being, the silver body of the fish would reflect the light and the black background would provide the contrast for the fish to be visible.
Photograph details: shutter 1/1000 sec , f/2.7 .
