This is one reason I do not like or use stem plants much. The other reason is that they grow fast (once established, my Pennywort took weeks then bang) and you are continually trimming them to keep them tidy. With rooted plants like swords, crypts, vallisneria, etc., they stay as you plant them and their root systems are sufficient to keep them anchored once they take hold. No fish like you or I have can uproot one of my Echinodorus bleherae with its 12-inch wide root system that goes down through 5-6 inches of gravel.
