Hello Jackie. Sorry to hear about that. Seems someone has some growing up to do along with learning the meaning of respecting someone's property. I would have been soooooooo upset as you obviously were. I won't go into detail as to what I would have done. Let's just say it wouldn't have been pretty

I think your fish will be fine. Too, I hope you get the apology that you and your fish deserve.
Stunts like this really make me angry. There is "no" excuse for this type of behavior. Ok, my rant is over lol
