The unusual term "Aphyoditeinae" is a collective term for small-sized tetra genera in the form of a subfamily, which could not be reasonably placed anywhere else. The world-renowned tetra specialist Jaques Géry introduced the term in 1972 in reference to the genus Aphyodite, but not as a subgenus, but as a vaguely defined term Aphyoditeini. The small Morse tetra, which is the subject here, is scientifically still undescribed. It has characteristics of many different genera, probably therefore even a new genus must be created for it. Until then, however, it needs a provisional name in the trade, because it must somehow be recorded in the merchandise management system. That's why we decided to group it in Aphyoditeinae when it was first imported in 2006. Others refer to it as Hemigrammus or Brittanichthys sp. - Frank Schaefer
