Plant safe cichlids

Depends on tank size.
But angelfish, most apistogramma species, keyholes, and discus won't touch plants.

i'll take it that you want to keep it with the rams, wich excludes some small but more aggressive species. I Could suggest Anomalochromis thomasi wich is easy to keep, beautiful and plant friendly.

or perhaps Dicrossus filamentosa or other dwarf pikes. these fishes areharder to keep but very intressting and leaves the plants alone. just a few suggestions. There are many more.
