The thing about cichlids is that your community harmony can change at any moment. With the demosoni being a juvie, he's not going to show aggression until he gets a bit bigger.. more numbers keep this down.
You may have a demosoni that will never bother anyone, but, it's a risky endeavor. I've heard horror stories of them taking out all the fish until he's the only one left. With Mbuna or other aggressive fish, it's better safe than sorry IMO.
