Hi Ryan,
I loved having a Gold Severum when I was younger, they are great fish to keep. However, like many Cichlids, they can be extremely aggressive at times and I wouldn't reccommend you keeping anything smaller than your Severum in the same tank with it.
I had to keep a single species aquarium when I kept Severums, as I found them to be too territorial to keep with other fish. This said, I have known people that have successfully kept Plecs, Pictus and Danios(although be prepared for an occasional loss) with Severums.
Good luck with your tank....I hope maybe you'll be able to post a pic or two of your severums when you have them settled.
