I had been planning on getting a BTA for awhile, but I just finally got the appropriate lighting in last week. Stopped in the LFS to pick up some food, and saw they had just gotten a fresh shipment of BTAs in. Took right to the rock, and moved only a few inches overnight. Unfortunately, it happened to move directly over the crevice that my emerald crab hides in, so I had to move the rockwork this morning to rescue him.
