Well this pair spawned again only a couple of days after their last lot of fry became free-swimming and my female has been back to stealing fry again.
She has a couple of very young fry that she has been mouthing and keeping watching on. She sometimes accidentally gets one of the older fry in her mouth and the poor thing probably thinks it is being eaten.
Going to put an IAL in to see if she doesn't build a nest again. I have to say they are very good parents but I am getting a little overrun. Hopefully they don't spawn again for a while or I may have to separate them.
