First of all, well done for your pics. Yes amny times as I live in Malta and also used to work partime as diving inst. Have to check about that fish as in Malta there is one which is very similar but has a poisionous part.
<font color='#0000FF'>John 100% spot on. Now I think that I can point out which is which, we call it narly same Tracna in Maltese (Trachinus) The lizard fish as in the pic has a bigger mouth and more pointed in front.
