Anthony - a day later and I lost my copperband too. I found him a short time ago sucked up against the Vortech. I'm not sure if the Vortech got him or if he was already weakened by not eating. I think most likely both, although he appeared fine earlier today. I removed him from the suction of the Vortech and he was still alive, just barely, but the upflow from the pump kept pulling him back. Put him in a separate container but he only lasted a few minutes after that. No sign of any disease - probably weakened by starvation. I knew ahead it wasn't a good fish choice, as they're known to be difficult to keep, so I can only blame myself.
