I don't have any in this list, but out of curiosity. Technically speaking, can all of these species be kept together, if all of them are at their maximum size?

-Redtail Catfish
-Tiger Shovelnose Catfish
-Redtail-Tiger Shovelnose hybrid
-Piraiba Catfish
-Jau Catfish
-Iridescent Shark
-Paroon Shark/normal and short bodied variant.
-Giant Mekong Catfish
-Bagarius Bagarius
-Bagarius Yarrelli
-Channel Catfish
-Blue Catfish
-Flathead Catfish
-Sharptooth Catfish
-Wallago Attu
-Wallagonia Micropogon
-Wallagonia Leerii
-European Wels Catfish

Remember, this is just a hypothesis. Don't house all of these together unless you have a literal private lake. Firstly, I'm not talking about Water Parameter Requirements differences here. Secondly, what do you think will happen keeping all of theses together? Lastly, do you think all of them, each at their maximum size, will be able to eat each other? If so, which eats which?
 
If we ignore water parameters and assume you keep them as adults, that tend to mellow out a bit in captivity, and don't reach their maximum size in the wild for the true monsters on that list, list what is typical in captivity, then, given a massive space, it should be doable for most if you find a way that everyone gets enough food as some on that list are way more greedy thak others.

If we assume full size potential and wild instincts, the larger ones like the Piraiba or Wels will eat the smaller ones like the sharptooth on the first day. I remember seeing a clip of Wels fishers having a 2m animal try to eat their 1m animal on the hook. A 2,5m beast will eat a lot of the cats on that list.

Bagarius Bagarius is a dwarf in this list and will be eaten either way.
