Synodontis multipunctatus will grow to seven inches(easily) and keeping rooted plant's in place could be problematic due to the fishes habit of rooting around the substrate in search of food's.
The Synodontis petricola stay much smaller, and would create less issues IME.

My Condolences.
Lost my own sainted mother six years ago and a kinder ,gentler soul, I have never known.
Lost a sister last month, and my brother is currently on ventilator after bypass surgery.
Were it not for the serenity I get from fishing, and piddling with my aquarium's well...
