Kids, no way. They are always supervised and unable to get to the tank even if they weren't. They don't really bother with the fish anyway, to busy playing with toys and being kids. Again, I do understand the fish can't be 100% accurately sexed at this age, just looking for guesses. This site can get way too mathmatical sometimes, just go with what you feel if you feel like it. I love speculation, it helps with me deal with the anticipation for their growth. I do believe that this wang jumped out of the tank though, the murder scenario seems more far fetched every time I think about it. No smell as of yet, so the mystery still persists.
