Female Thoracochromis brauschi

[freshwaterfishfan]

Do the female T. brauschi have a little bit of red in the throat? I ask because I have 4 T. brauschi. Two are obviously males, very bright red throats, clearly visible single egg spot. The other two were suppose to be females but I wonder if they aren't sub-males. They have a bit of red on the throat. I can't reallly make out an egg spot, but I have been told this is a species with poorly developed egg spots, if at all.
Thanks
Steve
