Females, IME, are quite aggressive to each other. Much worse than males, unlike Frank's experiences.
Are they still not eating? High nitrates & generally poor water conditions can inhibit appetite sometimes & lead to diseases. What mare your water params & maintenance schedule like? How long have you had them?
I would say don't add a male in such a small tank with all those females...it's barely big enough for 1 female (ok...maybe 2) & 1 male to breed...at best. Females are small but feisty, males wimpy but larger...& you're overstocked if they do breed & you get fry.
But fish that don't eat don't breed either...tell us more...what do you try to feed, how often, water changes?
