>>How long do you think they will co-exist in a well rocked and planted 55. Eventually the angels (why did I buy them) will get too big but do you think I have a while?<< FWIW, I have a mated pair of Gold Angelfish (5-6 inch) in a 29 gallon tall tank with 5 A. gibbiceps (1 1/2 inch) and 6 A. borelli (1/2 inch), and a trio of Aplocheilus lineatus (killifish). The killies stay right at the surface, the Angels in the middle to upper region, and the apistos at the bottom. The bottom has lots of rock caves, some plastic plants and a few small terra cotta pots. Everything is amicable except when the Angels spawn. There have been so serious altercations when this happens. All of the Apistos just stay under cover for a few days. It's important to note that there has been no breeding behavior or attempts by the apistos. This may be in part to the presence of the Angel as well as other factors, such as water and food. I am not playing with the water chemistry and I feed mostly dry food with some live. Of course, YMMV.
