So I've decided that I am going to add my new apistos to my 29 gallon with one sole angelfish. My next concern since my hope is to breed them is how to i get a pair to form? My LFS doesn't have them old enough to sex yet so would it be best to buy several and allow them to pair on their own and rehome the others once I have an established pair? Or do they prefer harems? My other concern would be is this pairing of apistos and my angel be acceptable, should I be worried for aggression towards wither my apistos or angel? If anyone has any advice it would be much appreciated!
