Okay, bear with me. Here goes my try at uploading photos to show the BTA in my tank.
First photo is a full tank shot, the nem is barely visible behind the rock just about dead center (the vague orange higher up is my coral beauty).
Next shot is a closer front view.
Here is a front view close up.
Finally, a top down shot (the nem extends up between the rock work and back wall to get into the light when they are on).
So there they are, my Rose and Percula. A bit shy, perhaps, but cute, huh?
