Thank you!
Things seem to be going ok. The one that flops itself over on its face at night has an immediate reaction to light and starts righting itself. I'm just going to let it be... was considering trying to prevent it from slouching but it doesn't seem to be doing any harm. The other one's foot is much more attached to the rock today and no more gunk flew off when I blew water at it.
I let them get more light today and they don't seem worse for it. Still on a reduced lighting regimen though.
I'm much more hopeful now than I was Tuesday when I injured it.
