I agree with N0body Of The Goat's suggestions.
Peaceful cichlids will likely be bullied by the RTS or possibly even the opaline and you don't really get the interesting behaviour of the larger cichlids. Firemouths are relatively peaceful (especially for a CA cichlid!) but will still hold their ground. Sajica cichlids are also an option.
As for shoaling fish, Colombian Tetras or Buenos Aires Tetras should be fine as will anything that grows to at least 3inches
Your stock should look something like this
-1 RTS
-1 Opaline Gourami
-1 Bristlenose
-1/2 cichlids of choice (depending on size)
-6/8 shoaling fish of choice
