Here is a video update, it is not as sharp as I thought, maybe the quality has degraded a bit.
Fish always hang around the front part of the tank when im in the room half expecting some food.
Still ongoing and evolving tweaking here and there, but generally far more wild than when it was a few months old. Sometimes i prefer the eariler stages when the balance of biomass to hardscape was more equal. Yet jungles suit rainbows well.
