Croaking sounds like chirping

So my pacman is around 6 months old and he's finally trying to croak but its sounds more like chirping is that normal?

I've heard some squeaky noises coming from Lump's tank too. I noticed the squeaking about 2 weeks before I heard him croak, but was never sure where it came from.

yeah when i hear it i look over and he's kinda bouncing up like when they croak so i know its coming from him
