Missing duzzy dwarf lionfish

[Lilxxwojo1]

I have been missing my fuzzy dwarf for like a week. I've looked all around my tank and aside from moving all of the rock I've checked the overflow and everything and still no dwarf. Does anyone know if they bury themselves or something? It used to come out all the time and it doesn't even make an appearance for live food.

What else is in the tank? I think a fish like that would have a hard time hiding for that long. He might not be in there anymore.
