I don't know enough about this particular species to know what's normal for them but generally speaking it's not unusual for a new fish to take a week or even two before it starts eating regularly.
What do you mean exactly by pouty and barrel rolls? Is the fish bloated? Is the fish scratching up against things?--if so, how often? If it seems to be constant, like several times or more in an hour then I would take a close look at the fish's skin. Use a flashlight and shine it from different angles and look at the fish from different angles: do you see any kind of coating on it's skin?
Please post back with more information
