Fish Rapture

Ok guys, this is the weirdest thing...I have now lost 2 fish from our tank. Yes, this is another reason why the fish get no names. However, this is just plain bizarre. The first was an Upside-down Catfish. One day he just vanished...no floater, no little half eaten corpse on the tank bottom...NOTHING! Well, it's happened again. I can't find one of the Angel fish we just bought. He is white so, I may just be not seeing him...however, it's been 2 days since I've seen him. There is no evidence of foul play...again NOTHING! This must be what it's going to be like for those who are non-believers when the rapture occurs. Something to think about.
