Thanks for the generous comments.
Time for an update:
The riparium plants are all growing really well
The Alternanthera reineckii is growing well but unfortunately the new growth is no longer red. I guess my lighting is not bright enough or is missing some part of the spectrum. I'm currently only using a 50/50 mix of warm white and cool white LEDs.
There's slow but steady growth happening underwater too
The red and green tiger lotus in the back corner are putting out new leaves
I'm still having algae issues with the anubias but I'm getting lots of new leaves there too
Some shots of some of the inhabitants
SAE
Steatocranus tinanti
One of the my three Synodontis flavitaeniatus who are really hard to photograph because they're reclusive and also blend into the rocks and wood really well
Archers and my really cool hybrid synodontis
