New nem hiding

[KingReef]

I got a new nem from the lfs yesterday. In the store it was stretching out and huge. In my tank it keeps "walking" to the underside of a rock. The lfs tank had pretty fun lighting. Mine was very intense. Should I leave it alone for a couple days to adjust? I just tested my water, 1.026, ammonia 0, nitrite 0, nitrate 5, phosphate .25 and pH 8.0. it is attaching to the rocks and it's arms are extending.

I also just bought a rose BTA myself. It’s doing the exact same thing. Everything I have read and heard is just leave it be it will move where it is happy. It came partly out of hiding 5 hours later. Sorry pic is very blue took with phone
