Bubble coral letting out red stuff!

it's closed shut now is this normal as well

 

i have a mj 1200 and vortech mp20 set in reef crest. I have two other spots that i can move the coral to iff needed, one of the spots i was planning on saving for a future clam, as it's a large spot near the middle of the tank, the other one is in a small corner on the right up front, and it's on the opposite end of the powerheads where it's currently inbetween the two powerheads down on the sand, i liked that spot because it was big and open.

Think i should move it or give it until tomorrow and see how it is?

 

its back open, so strange, kind of reminds me of a clam with how they open and close

 

hmm im thinking i may have to sacrafice my future clam's spot, i dont know if it would be low flow or not though on the sandbed

 

i dont think its happy at all, its closed up again

 

here's some pics

FTS only a few other open space in the sand

closed shut bubble coral

inbetween both powerheads

 

now its open again, im so confused

 

I haven't had one so I don't no if it is normal, but I do know a lot of LPS coral will do that as part of their normal activities. I would think that the bubble coral is no different. It could be cleaning itself off or just trying to get used to the flow in your tank. Give it time and observe it's reactions before moving it around.
