My elegance is a stone cold killer

[JOEfromHAWAII]

I've had a pair of mandarin goby for over 2+ year and they have been fat and happy without any thing picking on them. Then today I came home to this!!! Has anyone have any experience with this? This fish has had any issues and I've had the elegance in the tank for well over a year now.

Btw my clowns have never picked on my mandarins. So I'm at a total loss on how this happened

Did you lose both or just the one? I'm thinking maybe he died (looks like a "large" male to me) and floated into the Elegance.
