I would say its a female Mota.. Compare to the healthy female Mota pictured below it. Notice the black splotches near the gill plates?
I would also say it might of been neglected at one point in time because look at how large the eyes are in comparison with the body.. Possibly stunted growth? This could also be the cause of the awkward mouth and body structure. It looks very hungry, with torn fins.. All signs of neglect.
Could also be a JD/Mota cross... and then neglected.
Hope you feed it well and it bounces back to full health!!
