BB did become more unsettled with the additional Bluespot, but neither of them have ever jumped and they were to the point that they were swapping holes regularly without battles. They have more than a half-dozen spots in various locations throughout the tank. My mandarin, Pyle Wrasses, cucumber, and Palani regularly inspect all of these as well. Last night, my cucumber was invading GG's place and I was more worried about her than BB. BB was at the bottom back left side of the tank when I went to bed. There isn't a place already there, but two spots are within a foot of where she was. I just assumed she was checking out whether she wanted to go back to these places or that she would build another one. Sometimes the Palani will make a sudden dart across the tank. I wonder if that startled BB. I am still puzzled, she had to have morphed the netting enough for her to pass through it. I need to develop a net top with an escape route (like deer-fencing has ways they can get back to the other side).
