Nothing much, just a link to pictures of Heteranthera Zosterifolia in natural habitat.
I'm surprised they grow in sand, and in bushy form without anyone's pruning,
unlike what I have read and imagined.

I suspect the water is somewhat hard too. Since a tributary, Rio Olho d'Água,
is from a (limestone) spring, even itself is also a spring.
Again, unlike what I've read that HZ likes softwater.
