/fishbase.org/Photos/PicturesSummary...mp;what=species Look carefuly at the dorsal and caudal (though this one's very pale - top one, BTW, the bottom one's female). Some thick-lipped gouramies also have this little black line where their mouth is but, again, it's impossible for me to see whether yours has it. Finaly, size - thick-lipped gouramies stay about 1" smaller than bandeds. How large is he? If he's over 3-3.5", he can't be a thick-lipped.
