Had the same thing happen to me a while back. I should shade mine to see if it will change color too. Where did you get yours from?
I found which rock mine slept in and pulled it out at night while it was sleeping. Sometimes they will bury themselves for the night and you can snatch them there.
Tentacles on the disk? Or the whole polyp? I once siphoned a good sized chunch of a hammer coral and popped a bunch of it's tentacles. It healed in about a month and now it's twice as big. You shouldn't have anything to worry about.
That's more like it. My parents found it while claming and neither of them had their fishing licence, only their shellfish licence, so I told them that they should probably just let it go.
3 polyps.
75 gallon DT and 25-ish gallon sump, 2 x 20K 250w MH and 1 54w t5. Mine opened during the car ride home from Salem and stayed open until the lights went out last night; I'm feeling lucky.
