Happy to hear everyone is eating, it's always the first meal that is the hardest when they're settling in. (Unless you're an albino Sen haha)
Re: the big tank scape - maybe you could add some driftwood to your tank? I had a really large amount of rocks in my tank when I first set it up and it was fine. How much rock are you talking?
Check the QT tank every day for ammonia and nitrites so you can do a WC as needed.
