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.

Hi Nipat,

Good find. :cool:

It is fascinating to see the natural habitat.

Though your point is well taken, I suspect you underestimate the amount of “pruning” that goes on! The prey for those big prey fish are feeding on something. Those Pacu are omnivores and consume a lot of whatever is available.

Then there are the 'Serpae’ Tetra wherever they are, there will be all kinds of small invertebrates.

Interesting the plentiful CO2 at around 8-ppm later scrubbed by the rapids. Hard water is of course from the same source as the high CO2, limestone. :)

If you click on part 1 all the vascular plants and an interesting comment about cyanobacteria.

I liked the massive amount Echinodorus macrophyllus, which is a nice aquarium plant though is primarily harvested as a medicinal plant. :cool:

Thanks,
Biollante

Glad you like it. :eek:

I was too excited to look at part 1 and also overlooked the water parameter below each page.

It echoes Tom's advice: most plants do fine in hard and soft water.
