Then it's good for the pictus because they like open space for swimming but you would need more hiding spots for the Synodontis if there are a lot of them. They like hiding spots more than the Pictus do. ( Note that these Synodontis do not get to 6" and the Pictus max out at 6" in the wild so you will have them for quite a while for them to get to that size.
For what it's worth, a nice school of Pictus, 12-15+ fish, is an amazing sight to see as they generally school together and when it's feeding time, they become a "whirling dervish" of spots and antennae during the frenzy. A real competitor to Piranha in the feeding frenzy department.
