Aphyocharax rubropinnis Pappenheim, 1922 A. rubripinnis Lowe, 1970 (lapsus calami) The bloodfin tetra (Aphyocharax anisitsi) is a species of characin from the Paraná River basin in South America.

[3] Its notable feature (as the name suggests) is the blood-red colouration of the tail, dorsal, anal and adipose fin, while the body is silver in color.

Bloodfin tetras are extremely hardy, making them popular with novice fish keepers.

They swim mainly in the upper and middle water layers and are highly sociable fishes, mixing well with other types of tetras and tropical fish in general, so are often kept (like many other tetras) in a community tank.

The eggs, being heavy, fall to the floor of the tank or water body.
