Cheers dude!nice tank, the rocks on the left look great. on the right it looks like multiple rocks are lined up front to back? it lacks a bit of interest and that makes the tank look less balanced in my opinion.
I also think the scape would benefit from a midground plant around the rocks, making a more gradual transition from the carpet to the vallisneria. Otherwise it is a really nice and healthy looking tank, well done!
they have the shade of the rocks and the Valis, that's where the cory's chill mostlyAfraid I can't help feeling sorry for the fish in Iwagumi Aquariums, must be like being in the California sun all day with your shirt off. Is it a cardinal sin to add a few floating plants?
Tank on the whole looks nice though!
