Perhaps it is just the picture angle giving the wrong color but that does not look like a true cuban gar( Atractosteus tristoechus) but a tropical gar ( Atractosteus tropicus). It you want to count his lateral lines, if it has less than 56 it is a tropical gar. If it has around 70, it is a cuban . Of course a cuban has a very wide bite and is more olive in coloring.
