not pm to me. i'm pretty sure that if you target feed the i siphon the clam will immediately retract, and send everything through the e siphon. unless you can do it so gently that it creates extremely low flow. if you're determined to use more than Reef Chili daily, water column is best\ imo
I'm glad to hear you don't see the pinched mantle - in fact, possibly with some embarrassment, I think I might have figured that out. Flow is high along the glass since I put those rocks there, and perhaps the clam is just avoiding haven't its mantle flap around.
I don't think a rock is adhered to the bottom of the clam, but I'm not sure. This is all I see when it leans to the side (bad pic):

I'll think on the feeding for a bit.
