I do have 5 fish tanks with different fish, but right now, my heart beats mostly for the cats

A quick list about the most important ones:
2 Ameiurus nebulosus (brown bullhead) both about 30cm (11.8") each of them has a 90 gallon (330L) tank for itself.
10 Synodontis Grandiops (most of them are children of wild caught grandiops) about 7-10cm (2.75-3.9")
5 Synodontis Grandiops (bred them myself) about 4cm (1.5") kept separate in a 130 liter (50 gallon) grower tank.
1 Synodontis Schoutendeni (looking for 4 more)
1 Synodontis Pardalis about 15cm (5.9")
1 Synodontis Hybrid about 20cm (7.8")
2 L 114 about 6cm (2.3") they will go into a bigger tank as they grow big
3 Agamyxis pectinifrons 1x 20cm (7.8"), 1x 15cm (5.9") and 1x 8cm (3")
Most of the synodontis are in one 90 gallon tank, but I will put the S. Grandiops separate, probably with the younger ones, cause I think it's too much for a 130cm (51") long tank. And the rest of the Synodontis will go to a 720Liter (194 gallon) tank.
I got the Synodontis Hybrid and the agamyxis pectinifrons from an owner who had to give up his tank (health issues). He told me that the Synodontis should be an eupterus, which obviously is not the case.
I love this hybrid, especially because he is like my young synodontis grandiops. not shy at all! He is out during the day, coming up to the surface and plays with my hand when I do the weekly waterchange. He has several hiding spots, which he uses, but comes out if he sees me near the tank. I know his behaviour is not normal, but I have to say, I kinda like it.
Lets get to my question/problem, shall we ^^
I read a lot in this forum, also to identify my synodontis hybrid. I guess it's not possible, but I still wanne give it a shot. Maybe you do have an idea what blood could be in its veins.
Here are some pictures...(not just of the hybrid)
