They should. Consider adding a school of tetras and perhaps some corys. Unless you want to spawn them in which case leave the tank devoid of tankmates except perhaps a bristlenose pleco or some otos. Angels will eat their eggs before letting other fish do so. They will also seek to drive off other fish to protect them. Tetras, corys, otos and bristles all should be able to stay out of their way.
That tank is about 40 in. x 20 in. x 40 in- a 65 gal is 36x18x25.
Your angels should be fine in such a tank. Sounds like a really good tank with lots of plants.
Angels are really gorgeous fish when they are adult. Mine are about 20 cm tall with fins. They also live long, my oldest was about 14 years.
