Nice large conch there.
Wonder if schools are thinning to much and are hard to just dive through
and
capture some food on-the-fly?   Or is this just  'great fun'...?

Makes me wonder if they gathered a dead shell or was able to empty it.

Perhaps a rapid assent would expand the gasses within the shell cavity used
to buoy the conch normally and expel the snail. - It might have been the
first food, then the small fish swam in to get what was left - leaving what
we see as the 'game is on' mode.

They are smart and learned the method somehow.  Likely watching a
Captain Nemo show on underwater TV !
