I get home today and the damn Xenia's I've been asking you guys about are GONE!!!! just a small clump of the base and a few extensions (which seem to be pulsing btw) My question is who's the culprit?!?! Current residents are 1 clown, 1 Banggai Cardinal, 1 Yellow Tang, 1 Porcupine puffer, 1 pygmy...
