I didn’t notice but it’s possible, sadly no post mortem as I’m out of town, and had the fish sitter dispose of it.Sorry for the loss. Did you notice its belly. Was it sunken in? Leopards can have a sunken belly pretty fast after eating.
I see what people were saying about them being heartbreakers. Beautiful fish but sad to lose it seemingly out of the blue. Everything else, including the chrysus shipped with it are doing great.
