I saw you posted on another thread that you have some Moneywart with new growth that is thin. When I moved and my plants went from a tank with water of 6.4 PH to a tank with water of 7.8 PH the growth rate of my Rotala Indica slowed drastically and the little bit of new growth was almost microscopic green leaves instead of the lush reddish green leaves it used to produce. I gave it a couple months to rebound but it never did. The Moneywort may be reacting to a change in PH in your tank from the lake it came from. It doesn't sound as drastic as my plants so even if they don't bounce back and grow a little thicker they look like they are producing healthy growth that will look good in your tank.
