I have seen just about every kind of fish I have kept yawn. I seem to
remember reading that it had to do with irritation, what kind I cannot
remember. Sunfish species, especially those with larger mouths, will often
after yawning snap their mouths shut several times and lurch forward at the
same time. I have even seen large and smallmouth bass do this in the wild.
So , apparently there is information out there on atleast theories to why
fish do this.
