Your angels will quickly outgrow your tank- I hope you plan to upgrade. For now, I agree with the suggestion for otos, or you could add some tetras or rasboras instead, or a group of small corys.
at least in my tanks..all my angels will eat oto's..and I have seen the results f angels that could not quite fit an oto in ...ever seen the oto's defense mechanism?

there really isnt such thing as a "small angel." all angels that are commonly found in stores will easily make it to 6 inches, and will attempt to eat small fish such as neons, cardinals, small guppies, and otos.
