This actually applies to many of the characins--tetra, pencilfish, hatchetfish. Compared to the barbs and danios, most (but not all) characins are not particularly active swimming fish. In the cyprinids, most of the rasbora species are much the same.
The key is their natural habitat, which is indicated in the profile of each species. They naturally occur around aquatic vegetation, branches, overhanding vegetation. They obviously swim, but fairly sedately, with no where near the racing around the tank that more active fish exhibit.
As for tetra species, most in the Rosy clade of Hyphessobrycon will spend most of their time in shaded areas under floating plant cover or under the leaves of the larger sword plants. Rosy Tetra, Roberts Tetra, Black Phantom Tetra, Red Phantom Tetra, Bleeding Heart Tetra are in our profiles [click the shaded names]. The Paracheirodon species are also quiet and prefer being among plants: Neon Tetra, Cardinal Tetra, Green Neon Tetra.
