looks like a female.
I used to breed these guys and I noticed that not only was the female alot more of a deep red color with bright blue blotches,
The male tends to be more slender, more of a terracotta color fading to a scarlet red on his sides, smaller blue dots and less of them, and mostly of all the male I had when fully mature had a small somewhat noticeable nuchal hump. not like an american cichlid or anything but enough for it to be counted as sexual dimorphism.
And of the pair I had my female looked more like yours. do you have a picture of the whole fish from the side?
I guess if it is the only one you have it will start digging pits if it is a female. It is a beatiful jewel either way, do you keep it with community fish?
