Other than coloration, sexual dimorphism is slight, the female having a very slightly larger belly. During the night, the copper and black become silver as the fish rests - the color is reactivated once the fish becomes active in the morning. The fish are transparent except for the fact that their bodies have an overall copper sheen. Silvertip tetras have a black area at the base of their caudal fin. They differ from most other tetras by lacking a small second dorsal (adipose) fin. Both have white tips on the fins, hence the name. The males have a copper color, the females are more pale and silvery. This small fish reaches up to 3 cm (1.2 in) in standard length. Silvertip tetras are slightly more aggressive than other comparable smaller tetras, observed occasionally to nip other similarly sized tetras.
