these are my last spawn, and I am 90% sure they are both female. and they just had a nice meal so their bellys are a bit full. and I just realised that they are 3 months old today 
this one I am fairly sure is female
this one...fish on left, I first thought might be male, but now is starting to look very girly to me, also keeps jumping the divider to hang out with the other one, thus the together picture before I seperated them again.
