Communication and Perception
Green neon tetras transmit sound energy to the auditory organ by the use of a Weberian apparatus. This structure allows these fish to have better hearing characterized by large bandwidths and high sensitivity.
In addition to their hearing, green neon tetras have eyes, and can perceive visual signals, although the role of such signals in their commmunication has not been documented. Tactile communication may have some role in mating.
Communication Channels: acoustic
