Aquarius Rising

Do you all find that a person with an aquarius rising will exhibit the same characteristics as a Aquarius sun? This person has a scorpio sun, how would that affect his general personality, he is a commitment phobe, has an intense need for space, is very fixed

no that's similar to scorp - scorpio needs a lot of privacy, secretive... when you first meet them, they may exhibit aqua sun characteristics but after talking to them for a while, the sun/mercury, etc takes over.

they might be commitment phobe if you don't fit their idea of a partner or the feeling hasn't moved them enough - same as all fixed signs... they will not adapt.
