I got mine about a week ago and it turned purple and wilted all the first day and that night. I got on here and flower assured me that it was probably Ok becuase they are somewhat hard to kill. She was right. mine shrivles up to nothing every night after an hour with no light and then about an hour after the light is turned on in the morning its right back fully streched out again. Mine still havnt started pulsing like they did in the fish store, but I think my parameters are still a bit wacky for it to be totally in its element. I dodnt know about the smell, but unless it has melted away Im gonna go with Flowers advice and say its probably fine.
