Over 200 fish from three native species have been released into the Saigon River in Ho Chi Minh City in Vietnam, as part of an effort to protect the city's biodiversity.
The fish include two species that are very well-known to fishkeepers: Siamese fighter (Betta splendens) and Croaking gourami (Trichopsis vittata), along with the Sidestripe rasbora (Rasbora paviana), which is less commonly encountered in the hobby. They were bred by the city-based Wildlife at Risk organisation.
The fish were released in the river's Cau Den Canal in District 2 by a group of students belonging to the We Love Nature club, which is run by youth magazine Khan Quang Do.
The release was timed to mark the International Day for Biological Diversity (or World Biodiversity Day) on May 22, which is a United Nations–sanctioned international day for the promotion of biodiversity issues.
