Well... Big Blue died today. Not sure if it was old age or if he picked at the Foxface Rabbitfish one too many times and he poked em....... I got a pic of his very last swim. He swam to the back of the tank and then went sideways. I pulled him out and had some s.w. in a bucket, so I put him in there with a small filter and an air stone. A few hours(maybe 2) I went to look again and he was almost black in color and on his side, not breathing. Whatever killed him, did it quick. He seemed fine this morning and the rest of them seem fine too Actually the Foxface is looking a little weird right now. Hiding under a rock he's never gone under before. Maybe Big Blue just wouldn't let him under there before...hmmm
