ACtually, there not that bad to feed, keep lots of phytoplankton available, live phyto preferably, like DT's Live Phytoplankton or culture your own. (very easy to do) As for him jumping around alot and getting wedged in the rocks and stuff....this is normal. He'll keep moving until he finds a spot that nice and shaded for him and not too high a current but enough to bring food to him....if you are not target feeding him, he'll keep moving looking for food though. Also might add that the first flame scallop i purchased hid from sight for several months. They do not like the bright lighting and will hide from it, even if it means behind all your rockwork where you'lln ever see him. They do not utilize the light at all for feeding, such as clams and corals do so you much provide food. MUST! And they can eat alot too, so keep that in mind.
