I know that they can "croak", but i keep hearing this loud, chirping, whistling sort of sound emminating from my tank! At first i thought it was my bubbler, but its not as it still persists if its turned off. So i was wondering, can Sparkling gourami chirp? Because if they can, its the cutest noise ever from a fish 
If it helps, it sounds kinda like "pew pew pew peeeeeeew"
