C. parva is a painfully slow grower and makes Anubias growth look like Sunset Hygro or Hyrgophila sp. Ceylon in comparison
I had it for 6 months or so and if my memory is correct, I had one maybe two new leaves grow on each plant in this time. I think I had it planted in 2 year old Eco Complete that was in my current 75g tank at the time.
It may do grow a little faster in a more acidic substrate than I typically use. If you can add some peat pellets underneath them to acidify the substrate around them they may grow a little faster but this is just a guess.
