| Pseudorasbora parva | Male | Male sexual dimorphism | The sexual dimorphism becomes pronounced during spawning. In males breeding tubercles appear on the head. The greatest accumulation of sharp tubercles is located in the anterior part of the head, on the frons, near nostrils and below and above the eye. Few tubercles are observed also on the lower lip. In that period the males darken distinctly, and their fins become black while the operculum gets violet | Absent |
