HELP! Have a sad Elegance

[RC775]

I've had my elegance for about 6 weeks. He seemed pretty happy at first, but is clearly not happy now. I've tried repositioning him to adjust flow and light, but I can't seem to get a good combo. Everyone else (Buttons, Hammers, Torches, etc.) seems very happy, so I don't think I've got a water issue. Does anyone have any suggestions?

Here's the latest on him. Pretty well tucked in. This is normal after a feeding, but he's just not coming out anymore. It's been a little worse each day for the last 5 days.

Well, I read all the articles I could find and I'll just hope it improves. It is now in a fairly well shaded area with low-moderate flow. I'm going to step up my calcium dosing a bit in hopes that it might also help.
