Fish Compatibility

HI

I was wondering which fish i can mix with my current fish that i have, and i do not want agressive fish hehe.
I have...

1 red eye tetra
4 Platy(2 male 2 female)

First id add some more of the tetra, there fish that need to be in larger groups to feel secure. Secondly it also depends on tanks size, most likely some other forms of tetra, danio, guppy's, cory's etc.

i have a 20gal, also is that why my only tetra is agressive towards one of the female platy.. he seams to chase her and tries to nibble at her. so ANY type of tetra or the same red eye?

This could be the reason, somtimes fish that feel insecure may lash out at others (much like any other living thing), id go for maybe 5 more red eyes? You'll then have a nice shoal of them and can concider a few (not alot) other small fish to finish the community
