I’ve never kept festae but my experience with aggressive cichlids tells me that no hiding spot will be safe for the female if he decides he wants to kill her. The hiding spot would work with the catfish because the level of aggression towards the catfish would most likely be less than towards another cichlid, especially the same speciesI’m thinking If I make hiding spaces for the female where the male cant get in would that be ok and I’ll see if I can find a breeding pare then If that doesn’t work I could get red terror with silver dollors maybe
