WELL Unless their being Abducted by Alien Fish from a Paralel Universe/Another Planet.
I've got a possiable Solution for you. I've never had this happen Myself.
But I remember reading, in a book, Which I still have.
That sometimes especally if you live in the country and have an OPEN Well where you get your Water From.
There are small things Called "Hydras" that can live in the water of the well, they aren't very big, that WITHOUT a Magnafying Glass they are almost impossiable to see, They come out in the Dead of Night when your Lights aren't on and Attack a Fish and are capable of eating one in a Very short Period of Time.
I know this seems Stpid, and I'll probably get plenty of Laughs over it. (BUT)
I just thought it was WORTH something Checking Into...
GOOD LUCK and KEEP US POSTED...
