Ever since I got my first BTA she has stayed in the same place. Always happy, extended out of her little hole to show off, ate great, got mad on occasion when a hermit got close, but today she looked like this.

100 1046 - Does this look like a BTA split?

Her foot is still very well attached by the looks of it. I read that they will stay attached to one rock and stretch to another rock to split. I was curious if this seems like that? I am not sure exactly what brought this on though, I didn't have time to test my water levels, but everything else in the tank is doing great when I left.
