Looking good. Hopefully it will move to the front side of the rock for you at some point.
Might have to play w/ PH to get proper flow towards it, maybe even move to side of tank, or bring it more towards center and bounce off front panel
My vorts were originally in back, but I ended up having to move mine to side for better flow dispersion and not blasting nem, though it was putting up w/ it, it did make minor shifts at that time.
Now it sits exact(fingers always crossed as I say that)
I'm pretty confident it looks happy and well sit though
If it stays settled on the back like that for a few days and the foot is only on one rock I'd try just spinning the rock around. I did that with one of mine and it still stayed in the same position on the rock after I moved it. I kind of feel like once they find the spot on the rock they like they sort of set a firmer grip on the rock and won't move as long as the conditions you place them in are still good. That's been my experience at least.
You need to load it somewhere online, like YouTube, then link it to your post here.
I like to place the PH opposite to each other rather than on the back wall. It give better random back and forth flow. Random reef crest not synchronized with each other.
