I think most plants are going to go into the intake
and baby tears grow tall. they are no carpeting plant.
HC baby tears carpet best in high light and CO2 injection with fine substrate.
I remember keeping
Hygrophila corymbosa before. if you rip off the lowest leaves, it will leave a thick stem and all the foliage should be at the top, hopefully out of the filter intake reach. any broad leaf hygrophila should have a thick enough stem.
