I did not realize they could be predatory.
I sure know they are territorial, but this is usually directed toward other Anabantoids that want to share the surface area.
Occasionally I have heard about Dwarf Gouramis being so aggressive they need to be kept in a separate container, like a Betta. I do not know if the aggression being reported was territorial or predatory behavior. Separating the Gourami stopped the problem.
