Now i have one question here, if your male is yellow with a big spot in the middle of your body, are you sure you have a male. I have females with lyre points on the caudal fin like a male would have. My male also has black on his pelvic fins, but never turns yellow during breeding.. I have 2 groups of 1 male and 3 females in seperate tanks. My fry are at about 3/4 inch and i cant tell the sexes yet. I have found Bitaeniata to be the hardest apisto i have to sex at this size. The only one i've found worse is Resticulosa . My thinking here is you have all females. I hope for your sake im wrong.
