Nice tank! Love the plants you have.
My main concern would be that window, I know you've blacked out 3 sides, any chance you can black out the top with full on canopy?
My fully planted tank was all blacked out on 3 sides like yours, there was one corner on the top, maybe 10% that allowed light in from a nearby window, low and behold algae sprouted from that corner, I cleaned and cleaned.. snails shrimp all nogo w/in 2 weeks of blacking out the top, it was all under control.
This is just my experience though. I'm sure our tanks are night and day so, grain of salt 🙂
Looks great! You want some bully discus?
