I have had three apparently healthy fish die and I'm trying to find a cause without success. The first was about a month ago, a blue-faced angel that I got from MACNA. He was eating well, no signs of ich, looking quite lovely and adapted well to the tank (he'd been in for about three months). One day I found him stuck to the overflow, not quite dead. I removed him, but he died shortly after. Two days ago, I came home to my blue (hippo) tang dead. He had died recently because none of my CUC had started on him yet. It seemed like he might have choked himself to death by eating too big a piece or algae, because there was some hanging out of his mouth and I pulled on it and a rather massive piece came out. The blue was a rescue from Petco who was recovering splendidly from a case of HLLE. No signs of ich, ate like a pig (obviously), and he had been in my tank about a month and a half. Finally, I came home from work yesterday to find one of my baby snowflake clowns stuck to me vortech. Again, no signs of ich, eating well; I got him at MACNA so he'd been in the tank almost 6 months and seemed fat and happy. I will test all my parameters when I get home, since I know that will be asked, but things have been stable for quite a while. I have a ton of other livestock that seems fine but if there is a problem that is systemic I'd like to take care of it before it kills again! Please help, I am feeling very discouraged by this, and it comes right before I was planning on getting back into the coral side of the hobby!
