Not sure I follow everything...where are the fry grow-out tanks? And where are the large Synodontis going?

One empty 10G is not going to allow you to raise fry for food $$. And I would not put larger synodontis in a 40 breeder...a trio of lucipinnis would be the max for a 40 breeder.

I did not figure out all your filters...you want 8X to 10X GPH for the African tanks.

Saulosi works in a 40 breeder.

The Tangs work.

IDK CA and SA and Asian stocking.

Note although a lot of Synodontis (lucipinnis and others) are sold as Petricola in the US I have maybe once in 10 years found them sold here despite many guarantees of true petricola. Likely you have lucipinnis which go for $10 around here.
