A Rotkiel Severum or a Mouth Brooding Severum could work with the Angels but dont get Greens or Golds as they get bigger and be careful not to get Orange Shoulders as they grow large also.
Angels get to 6/7 inches and realistically your not going to get anything much bigger than them in that size tank its not really deep enough.
A group of Cupid Cichlids would be nice if you have sand
