I bought these two R. Imitators in March 2019, at which point they were ~4 months old. So they are roughly 16-17 months at this point.
I have never heard either of them calling.
I have observed them wrestling, so they are living separately under the assumption that they are both males fighting for territory.
Temps are between 69-74, and humidity in the 90s via misting system.
Can anyone determine if these are both in fact males?
Is there a way to promote or initiate calling?
Any input is greatly appreciated!
