Hmmm. I have 80 watts over a 29 tall. Maybe not enough light? I'll shop
around and see.
Anybody want to trade E. parviflorus for Brazilian pennywort or rotala
indica? Got plenty of that....

Don't remember what they are. Might very well be quadricostatus.
As for crowding, now we may be on to something. The chain swords are
more crowded in the center of the tank, where there is more light and
they grow quickly. In the corners, where the bulbs do not extend all the
way to the edge of the tank, and it is shady, the chain swords are 2-3
inches as described.
So I need either more light or less light. My head is swimming.
