Adding many of these fish to an established planted tank is rather different than adding baby plants & hoping they establish in the face of the ravening horde
Fish can make life difficult for plants just due to vigorous activity around plants - substrate digging (clowns & cories on your list) & grazing for interesting food stuff - not the actual leafs (likely everyone on your list) & vegetation grazing ie the actual leafs, especially new developing shoots (likely rosy barbs & adult SAE & occasionally clowns) & swim gymnastics (larger rainbows, clowns, rosy barbs, SAE)
so it might be worthwhile to set up a plant "nursery" tank (who doesn't want another tank
)
If you're good/practised at growing plants, it's much easier to maintain a (non-ragged) planted tank even with your current fish group ... what sort of lighting, CO2, fertilizer, substrate do you have? maintenance schedule? tank size? fish numbers?
- I'm imagining a 150cm tank at least given the fish list
Hygrophila species are generally fast (easy) growers, the
Bacopas are smaller leafed, Vallisneria, Sagittaria, Microsorum comes in a range of leaf size, color, shape,
C calamistratum is generally not considered "tasty" (but a large plant can be expensive, it often takes some time to acclimate then grows steadily) ... plant heavily & you improve the chances for individual plants, starting with larger sized pots (older stronger individual plants) can also help.
Given the fish list, I doubt you'd have much success establishing any ground cover.
Also look at fish diet, providing fresh veg (try a range to find out what everyone likes), also spirulina enriched food (sometimes palatability is an issue)
