I have the orange and black lined clowns. Percs?

Three days and it still is in the upper rear corner of my tank. I fed it last night a chunk of HEB shrimp. She devoured it readily and seems happier for it.

I have a long tentacle that rolls around like a tumbleweed. I've placed it within crevices, within a rocky moat, within a cave that it can reach out for light to no avail. She sticks for a minute and within the day is loose rolling around the tank. She looks healthy but quite frankly I've run out of places to put her.
