My rose BTA likes crevices but never tucked itself away. As soon as I put my green BTA in the tank it was on the move like the fast and the furious. Now it’s hiding out in the back of the rock on the sand. I thought this was out of character for anemones being that they typically like light. Does anyone else have a green bta or any anemone for that matter that is hiding out in a dark location and/or on the sandbed?
