A large number of fish from the Potomac River have been pulling a RuPaul and changing their sex.

Scientists from the U.S. Geological Survey pulled a bunch of male sea bass from the river and found they were producing eggs—something boy fish don't usually do. The culprits of the Victor/Victoria change: chemicals in the water that affect the lil' swimmers' hormone levels.

Oddly enough, this isn't the first time the fishy flipflop has befallen; intersex fish have popped up in Chesapeake Bay and off the San Diego coast.

The Potomac supplies drinking water to thousands of D.C.-area residents, who understandably fret that downing a glass of water might cause Johnny to change to Jenny. Water officials swear, however, that there's no cause for alarm.

“There is no indication that people should not drink the water,” says Thomas Jacobus, general manager of the Washington Aqueduct. The fish were unavailable for comment.
