Hello everyone, I've had a serrasalmus sanchezi for over 20 years. I got him when he was about the size of a quarter in early 2005. He lived his whole life in a 90 gallon planted display tank. He had a great personality he would usually hide behind his favorite log unless I was out and about then he would come out (he could recognize me versus my roommates since I was the only one who fed him and would come and pace the glass when he saw me).
He hasn't been eating for the past month, I usually would feed him mainly shrimp and Mahi Mahi, with carnivore pellets pushed into the meat to subsidize his nutrition. But for the past month he just hasn't been the same not coming out from behind his log and completely uninterested in food, usually he would grab the food before it hit the bottom. After a month of no eating I even tried to feed him some live guppies (I usually never feed live because of disease risks) he had no interest.
Yesterday he was breathing really heavy all day all water parameters are fine temperature is at 77. When I got home from work late last night he was laying on his side flopped over on a piece of the log barely breathing so I pulled him out and put him in a small bucket of aquarium water mixed with clove oil and then euthanized him. I was sad, and honestly wish I had done it sooner before he was in such a state, but I kept thinking he would come back around.
