Most corals tend to be slimy to the touch. I would not worry about the leaning it is probably going with the flow, sort to speak if it continues to lean on that LR it will probably attach itself to it, which is a good thing. That is how they spread. I do not think the polyps are fully extended, give it some time, they will!
Still looks similar to mine . When closed it has a beautiful blue/green color and when open more pink and brown.
here is some pics of mine open and semi closed you can see on the closed picture that some of the branches ressemble yours.
I bet buy the end of the day yours will be open in its full glory!
