He is beautiful and you have a great set up...BUT IMO his tank is just too large for him right now. Maybe you could divide it in half for awhile or add even more plants for cover? But I personally would temporarily move him into a small tub til he was eating and less shy? And maybe try a really small live mouse after he settles first to jump start his appetite? I also have the same hide but my girl is a whopping 450g and its stuffed with moss so she feels secure, so maybe a much smaller hide to start. They like it to be small enough that they touch the sides.
But I'm just starting out this year so maybe some more experienced keepers could suggest something.
