Playing around with my new lens... and for a quick update
I took out this echinodorus uruguayensis out of my tank. The plant takes up so much space and would be better in the pond.
If I have the chance, perhaps one day I will make again a setup but looking more to something like this, something combined with outside garden. Living room or dining room next to such view would be very nice.

This setup is taken from Singapore zoo. It is the new proboscis monkey display if you wonder.
Monkey on the dry land, and simple underwater view by the bottom.
