How's the circulation in your QT tank. I have found some fish skittish as heck if the flow is low. I call it TPS or Tidal Pool Syndrome, where the fish thinks it got trapped in a tidal pool and is easy pickings for any predatory bird ect.
Even lots of hiding spots aren't enough in my opinion. I have a couple of tangs and anytime I reduced flow, they will pretty much panic.
