Are you sure it is an SAE? (please do not be offended, just asking). Here is a good article on identifying them.
SAE's
Some of the fish that are similar are known to be aggresive. I have two SAE's in a 72 gallon with neons, cardinals, and rummys and they just spend most of the time with each other. They do not harrass any of the other fish. My pushy fish are my torpedo barbs.
