Unknown Killer?

I have / had a pink spotted and blue spotted goby in my 90gal. Today I was just watching my tank and saw what i think is the body of my Blue Spot Goby. I went to go grab a flashlight and camera but now it’s gone…

My pink spotted goby won’t go back into the rocks. It stays behind my overflow or my frag holder. It’s dorsal and tail are extremely damaged. I thought he might have fin rot? Or something is after them in the rockwork.

Any ideas?

Rock Hiding Ninja fish?

Maybe not seen but heard

Not necessarily either, but he said that he hasnt lost any other fish before… and hasnt added anything new for quite a while.

I’m stumped, unless one of the other fish decided it was going to pick a fight. Or maybe you have crabzilla in there…

No idea no spike in readings either.
