Xanthus just passed... I am frustrated and sad right now, it seems like I am battling a mysterious, fast moving disease that causes the fish to become lethargic, then, the next day, dropsy and die. I created a thread in the emergencies/disease section. When this happened to my female I waved it off as a random event but now that pretty much the same thing happened to another one of my fish, I don't think it is coincidental. I don't know what to do and am deathly afraid that I will lose another since at least eight other fish have been exposed to a fish that died of this. Sip Xanthus, you were a beautiful, fun fish who was full of personality.
