Loving your Goonch mate, love it. Cracking looking specimen and awesome that it's taking pellets.
You queried tank depth, how deep it should be?
I don't know if depth is a major issue to the species, imagine the smaller specimens keep to shallower water/pools perhaps to avoid becoming dinner for the larger catfish around - on river monsters Jeremy goes snorkelling amongst rocks looking for pretty big specimens and the depth must be around 6' give or take.
I think the width you've got in the upgrade is excellent, plenty of scope to provide both lots of hiding space and also open space on the bottom.
You could put two pumps either end of the tank to create more turbulent mixing waters, just an idea, probably the wrong one lol!
