This is hilarious. You've made a good acquarium capture (those are not easy for various reasons) of a hideous looking giant fish with a severe underbite and jutting jaw nose first into a compositional triangle. On the lower left you have two gentlemen with underbites and jutting jaws looking back at him with suspicion but the same expression. The eerie blue toning common to aquarium lighting is well caught and adds to the authenticity of the scene. Would not be as interesting if you'd tried to correct that lighting. Made me smile.
