Another one!
Great photographs Rocco. That bright blue piping is interesting. Here in Canada it's either white or a pale beige colour. In England white or grey but you can get black through certain specialist suppliers.
I think I see a Black Ghost Knifefish in the tube thing? I'm not sure how they are with lots of current and you may find those Glowlight Tetras are at risk as it grows. And they grow quickly!
My only criticism would be the substrate. I would use that in a Hillstream Loach setup but Botiid species and
Corydoras are better on a sand substrate as it allows them to dig easier without damaging their delicate barbels.
