You should go with only one of them. Personally, I would choose angels over red tails anytime. The red tail is a known fin-nipper and will do so whenver he gets the chance. Angels on the other hand are typically calm and peaceful. They are very pretty too, with many different color variations to choose from. You can keep one angel fish in your 28 gallon along with a shoal of 3 bleeding heart tetras and 4 small corydoras species, or a bristlenose plecostomus.
