possible hybrid, but whats the size? my xingu went through various colour stages, doesnt seem to wanna stick to one. at the moment he is full of spangles and the black line all but disappeared, hopefully it will come back. but he did look kind of like yours just not ass intense green, more yellow. the solid line and the slight barring is familiar to my xingu though. more spangles though, which is what makes me think it may have some orino in it. money is on xingu though.
