My Trigger is gone????

[Marlin65]

Not sure what happened to my little buddy he always comes out to eat.
I checked the floor and ripped the whole tank apart but am unable to find him.
He was about 3" so not a small fish. My parameters are good after 3 days so I don't think he is dead in the tank. Unless he is wedged in some hole but I checked almost all the rocks. He could of jumped but I can't find a body. I do have a cat though Hhhmmmmm.
Them maybe my nems ate them I never thought they got that big.
