The Mediterranean toothcarp, Aphanius fasciatus, occurs around much of the Mediterranean coast, from France and the Adriatic to Syria and Egypt. It mostly inhabits shallow lagoons, salt marshes and first order streams, and tolerates anything from freshwater to hypersaline conditions. Populations differ in colour and pattern but relatively little genetically, the exception being the isolated population in Lake Bafa, Turkey.

The grass carp, Ctenopharyngodon idella, is a large cyprinid native to the Amur River system in eastern Russia and northeastern China. Adults typically reach 800 to 1200 mm, making it a wholly unsuitable aquarium subject, though an albino form is traded. Widely introduced for aquaculture and weed control, it has caused serious damage to natural waters, and unwanted fish should never be released.
