They also have a fl spot at the mid-point at the base of the dorsal fin.
Fast-moving, nippy fish such as Tiger Barbs and Head and Taillight Tetra or Black Widow Tetras are not recomended as tankmates unless they are kept in a largish school, as they will try and nip the trailling fins.
The main difference between these and the Silver is the intensity of fl patterning in the fins - giving a lace effect.
