In another thread a while back I found out that Sebae's usually dwell in the sand. They typically don't extend their foot into the rockwork because their foot is much larger and less sticky than other anemone's that prefer to reside on rocks, like BTA's. Sebae's rely on their disk more for stability, so high flow might not be desirable. Ultimately it will move to where is feels most comfortable in your tank.

If it helps, I bought my sebae about 3 months ago and placed it in the sand where the rocks form a kind of bowl around it, it has stayed in that very spot ever since. There isn't exactly a tonne of light where it is, so I feed it a bit of mysis once or twice a week. It took about a week for my clowns to make their home in it. Their tenticles are quite sticky so it must have taken some getting used to for them.
