In aquaria,Pollimyrus isidori produce ‘grunts’, ‘moans’, ‘growls’, ‘pops’ and ‘hoots’ at various phases during nesting, courtship, and territory defense.
All five sounds are produced primarily at night. Territorial males produce grunts, moans and growls during courtship. Vocalizing is stimulated by the presence of a gravid female on the male's territory and decreases with the onset of spawning. Hoots and pops are given during agonistic behavior.
Grunts are bursts of acoustic pulses, stereotyped for an individual, with the potential as individual signatures.
The electric organ is silent during grunts and moans and is discharged at a reduced rate during growls.
The courtship and spawning ofPollimyrus isidori is described.
