Mysterious Disappearance!?!?

Within the past year i have lost two fish mysteriously! Ive never questioned it, but recently ive been looking for an answer. I know for a fact the fishes, a clown and damsel, didn't not jump out of the tank. One day they would fine, swimming and eating regularly, and then the next morning they were no where to be found!? No body and no evidence! These fish were lost at different times. Has anyone else had a similar situation? Maybe someone can close the books on this disaperence? Also, each time tank perameters checked out normal.

Thanks guys!

 

I have heard of clean up crews finishing off a fish in a matter of hours. My lone large hermit crab finished off a dead turbo snail in two days.

 

That is insane! I figured it was the hermits or the worms overnight.
