This small tetra, in which the male exhibits a reflective blue sheen on the body, is a relatively new introduction when compared to most of the other tetras encountered in the hobby. It first appeared in Germany in 1977 and since then has been consistently available, although not in large numbers. It is a good choice for community aquaria that do not house robust, overactive species.
