Thanks for the offers guys I was able to get some PVC elbows big enough for her to escape into but not allow him in. I got lucky at petsmart and scored a 20 long with a very minor scratch on one of the sides for $28 after asking the manager to discount it. Just got the 20 set up and moved some media over. It's nice when you get to the point of having everything to set up an extra aquarium. The only thing I was missing this time was the aquarium! I will not be adding any more fish into cichlid tanks without having dividers or a rescue tank available from now on.
