How about a hawkfish of some kind? Flame, long nose or a smaller one like a geometric pygmy hawk (actually an anthais).
All fish have the potential to jump. Something as simple as car lights passing through a window or someone walking in front of a tank at night causing a shaddow will spook a fish.
