I might set up my old 29gal tank cause I planned on getting a bigger one but I cannot right now

.I wanted a convict and 1 tankmate. I need advice. There are 2 options will one of these work or will both of my plans work.
1 convict, 1 firemouth, some tiger barbs(or some smaller other schooling fish)
or
1 convict, 1 salvini, and schooling fish.
The schooling fish are to act as somewhat target fish to help with aggresion.
thanks
