It occurs when two electric fish with wave discharges meet - if their discharge frequencies are very similar, each fish shifts its discharge frequency to increase the difference between the two. (wikipedia.org)
They found that when a sinusoidal electrical stimulus is emitted from an electrode near the fish, if the stimulus frequency is within 5 Hz of the fish's electric organ discharge (EOD) frequency, the fish alters its EOD frequency to increase the difference between its own frequency and the stimulus frequency. (wikipedia.org)
Stimuli above the fish's EOD frequency push the EOD frequency downwards, while frequencies below that of the fish push the EOD frequency upwards, with a maximum change of about ±6.5 Hz. (wikipedia.org)
