All about spell-like abilities part two

A spell-like ability has no verbal, somatic, material, focus, or XP components. Using a spell-like ability is a purely mental action, albeit one that requires enough concentration to provoke attacks of opportunity. It is quite possible, however, that a creature using a spell-like ability might add some gesture, word, or flourish just for dramatic effect.

So without verbal and somatic components and without any visible effect you didn't have any chance to identify a spell-like ability.
