Too much light for a bubbletip?

[MitchM]

I've got a couple of BTA clones in my sump, which is lit by a single 150w DE Aqualine, and they've been residing there for more than a few months. They have been the darkest BTA's I've seen for a while, and in the last week, one of them looked like it was dying. One day it started moving from it's position on some rubble, and then started onto the sand.(which, as far as I know, BTA's do not like)
On a hunch, I picked it up and placed it with some larger pieces of LR, and it promptly moved out of the light and into some shade. It's in an area now where it could move toward the light again, or stay in the shade.
It's nice and plump again, and I imagine it will be fine.
I didn't realize that BTA's needed a break from the light every now and then, but I've never had them living on rubble before, either.
I've probably never noticed their movement within the main tank to that degree.
