Well just my opinion... On ur next purchase, maybe u would consider putting him directly to ur MD? I don't have a QT so all my fish always go straight to MD, when I first got the regal he didn't eat for about a week, he did a very small amount of nipping on everything I threw in that first week, not nearly enough to survive a week I think. He did however pick my rock non stop, or maybe u can try live feed but seems like it loved pods. Still constantly picks rock in between all the feedings
