Mine is still tucked away in a PVC fitting. (I know he comes out sometimes, he's pointed in different directions when I peek in... but I've only _seen_ him come out once. Took a look around and went back in.)
He's in a 75 gallon tank set up as a QT, with a small bit of liverock that's got some caulerpa and chaetomorpha rubberbanded to it. I've taped black plastic bags over most of the tank, leaving just a couple of places that I can peek in through. Kept the lights dim for a couple of days, but the last couple of days I've brought the lights up - thinking that this is a diurnal fish, an algae-grazer who has need of sunlight in his world. Yesterday, I also added a trio of small (3/4") black-bar chromis as "dither" fish, hoping to increase the parrotfish's confidence that there aren't any big scary things about to pounce. I've offered blended foods such as Rod's and LRS, mysis, brine, NLS and Ocean Nutrition pellets, flake and fresh clams on the half . . . and no obvious movement so far.
