First, gourami and angelfish are fine--with suitable tankmates. Among the tetra there are varying behaviours. It is simply a matter of selecting the right species. And this can work both ways: one has to guard against tetra that are more likely to nip the fins of sedate fish, and also be aware that linear tetra are more likley to be stalked by gourami (the larger species) and angelfish.
This is really going to be applicable with any "centrepiece" fish, if by this term one is thinking of somewhat larger fish which will almost always be sedate. For example, any South or Central American cichlid falls into this category, as do the anabantids.
But "centrepiece" can also mean some of the larger shoaling fish from the characins, atherinids (rainbowfish), peaceful barbs, etc. But here too one just has to select the smaller shoaling fish (tetra) carefully. Activity level is a very important criteria. I also consider water currents (not all fish are equal here, and this can be very stressful) as well as the more obvious temperature and other parameters.
