When I look at both of them they both seem fine. Waving in the the current banging and weaving with each other. Both don't shrivel or show signs of stress. I was scared the Xenia would release some toxins if it was stressed or something. I'm going to upload a picture of the BTA later because it is in a crazy spot. The space that is has shoved itself into has 2 small openings formed by two rocks that are close together. It makes a figure 8 opening (little bridge in the middle). Half is sticking out one opening and half out the other. Seems like a very uncomfortable position, but it seems happy there. I got lucky that it is right up front though, I've read that these things sometimes like to head to the back where you can't see them.
