That should be plenty big enough. Just a good rule of thumb test for nitrates about once a week. If the nitrates are running high you are probably over stocked. But don't panic, just vacuum the gravel more often and perform more water changes. Angels are usually picky on water conditions so you might want to do a water change every other week just to keep them happy. Great looking fish btw lol.
