Frenchy keeps making this noise! What does it mean?

I definitely also have three distinct vocalizations from my males including the one you're referring to. I don't speak RETF for the specifics, but for sure it's breeding/territorial as the males do the calling 'at' the females but also much more so at each other when fighting. (Incidentally RETF wrestling is absolutely hilarious, I'll try and get a video as mine are having some sort of world series at the moment).
They don't actually breed in water, but in the leaves above it of course. Mine tend to call most while jumping/charging around the leaves and branches chasing each other.

Ah okay! So either way, hes definitely male! Good to know. Question, have you ever witnessed territorial calls between an adult male and a younger red eye? Like would Frenchy make that call even towards a female if that female wasnt an adult yet?

Yes, they shout at everyone. Males, females, young, me, nothing, whatever
