We had this phirahna one time and we used to feed it goldfish. Well, the bastard would eat like 5 or 6 at a time, then he would get full and quit. One time he ate a couple of em, then when he went to eat one, it got half chewed up and somehow escaped out of the thing's mouth. The escaped goldfish was gimpy, but didn't die. He was swimming around with only one fin for like 3 days until the phirahna ate his arse.
