The foxface and the powder blue should be fine with either of the two mentioned. Once you decide which one add it last and I would make sure it is smaller. Lions aren't real aggressive they will just eat anything it can fit in its mouth but they won't chase other fish around. The picasso can be aggressive - kinda a case by case thing - get a smaller one! I almost bought a powder blue tonight but they can be rather aggressive so I am going to wait awhile.
