I am very upset since Shuffle was one of my favorite fish, and only my 2nd death and first unknown death. He is an albino bristlenose pleco in my 29 gallon subtropical tank. It has been looking much chubbier than usual, but I assumed that was just him eating more than usual, since I have been dropping a bit more food in than usual (I was worried about the corydora eating all of his food). Now I am thinking he could have had impaction from sand? I changed the substrate from gravel to sand and he has gotten much more shy, but also much more chubby since. He was pretty active earlier today (I thought he was finally getting used to the new arrangement). Then I found him dead about 15 min ago. He couldn't have been there long since I was taking fish pics about an hour ago. I am checking my water parameters right now. I am very upset since he was one of my favorites.
