Archer fish?
I happen to have some pics of archer fish display, palud style. This one is mangrove setup with a fake mangrove trees. I guess they got good headache growing mangrove tree in high light level without spoiling the tank with algae, so they resolve to low light and artificial trees instead.
There are two connected display, L shaped with individual viewing windows.
Back to the pond...
Here you go, a full shot after some finishing job and the top part finished.
Water is a bit tainted, a good thing that you can see it filled around halfway of the windows. The windows frame is now also shaped to blend in with the rest of the cliff.
