I could be wrong, but I think the name sheatfish refers to the Eurasian wels
catfish (Silurus glanis)... and they get really, really big (4m, 200+kg ?).

I think the largest known FW fish is the Chinese paddlefish, (Psephurus
gladius). Maximum length is reputed to be in the range of 7m (21+ ft),
although that has been disputed by some authors. They have a sword-shaped
rostrum and are piscivores, in contrast to the NA paddlefish.

A close runner up are the various large sturgeon- Huso huso, Acipenser
transmontanus, and Acipenser oxyrinchus (and others, I think) are all known
to approach or break the 6m mark.
